New LiFePo4 Prismatic Cells sizes 306ah 314ah 320ah and more in 2024

Breaking this is likely the most important news to hit the DIY Solar and Lithium Lifepo4 Battery Off Grid community in 10 years. This really is going to upset the YouTube community apple cart. Especially that guy that lives in Australia who isn’t even Australian.

Currently, 280Ah and 300ah cells are the mainstream in Lifepo4 Batteries, but with the acceleration of technological iteration, the improvement to battery cathode and electrolyte technology in the past few years, over 20 types of high-capacity cells above 300Ah have emerged, these cells will take considerable time to enter the retail and B grade markets, but they are coming in 2024 and 2025. Some of these cells can be purchased now in very large quantity, but for the average joe, building batteries at home DIY style the best mix of value and performance still likes in the 280ah capacity cells over the next few months.

Super Large Capacity LiFePO4 Cells

With the rapid development of the energy storage industry, the market demand for cells continues to outpace supply. Many companies are increasing cell capacity through technological iteration. Cell capacity is growing larger, from 306ah to 314Ah, 320Ah, 340ah and 360ah and then to 500ah 560Ah and 580ah cells

The LF560K battery represents EVE Energy’s relentless pursuit of innovation and quality, built upon over 21 years of extensive experience in the battery industry and the strong R&D capabilities of its 3,100-member research team.

Currently, the mainstream energy storage cells on the market are 280Ah rectangular aluminum-cased cells. Many manufacturers are also reducing costs for downstream customers by improving cell volumetric density – that is, increasing capacity density per unit volume.

The 560Ah cell essentially doubles the common 280Ah rectangular cell size, equivalent to placing two 280Ah cells side-by-side. This aims to reduce PACK components and achieve cost reduction.

Although the 560Ah cell is not yet EVE Energy’s primary product, it has embarked on the path to commercialization. On February 1 this year, EVE Energy broke ground on its new “60 GWh Power Energy Storage Battery Super Factory” in Jingmen, Hubei, with 10.8 billion RMB investment. This factory will mass-produce the 560Ah energy storage cell. The 560Ah cell is expected to commence global delivery in Q2 2024.

Vision 580Ah LiFePOP4 Cell

On May 16, China’s largest battery exhibition, CIBF 2023, opened in Shenzhen. Thunder Corporation prominently displayed an ultra-high capacity cell.

The 580Ah ultra-large single-cell released by Thunder Corp is the largest capacity single-cell emerged so far globally.

Although the exhibit at CIBF appeared high-profile, it only showcased partial specs. The company claims 10,000 cycle life, 11kg weight per cell, 1856Wh nominal capacity, and 0.5C charge/discharge rate. But details such as packaging technology, mass production timeline, and delivery schedule remain unclear.

With over 10,000 cycle life, the 580Ah cell represents a two-pronged upgrade at both the cell and system levels, providing customers robust safety assurance and performance guarantee. Technologies such as low-expansion anode materials, full tab design, electrode surface treatment, and flexible electrode forming help resolve liquid infiltration challenges for large cells, enabling comprehensive safety protection and high cycle life through heat insulation, diffusion prevention, pressure relief, and more. This will better meet application requirements for grid-scale energy storage, greatly improving system safety, lifespan, and lowering life-cycle electricity costs.

Seeking the “Triangle Balance Point”

At the 320Ah capacity level, internal cell temperatures can surpass 800°C, exceeding the decomposition temperature of lithium iron phosphate and posing challenges to cell safety, energy density, manufacturing processes, and more.

Cell R&D also faces the classic ‘impossible trinity’ of high energy density, long cycle life, and high safety. Energy density is a priority consideration in nearly all cell design. Pursuing higher energy density requires thinner membranes and high pressure and areal density electrode materials. On one hand, such extremities make liquid infiltration more difficult, undermining cycling performance. On the other hand, thinner membranes and higher energy density materials also mean poorer safety. There is no avoiding the trade-off between energy density and performance. Prioritizing energy density may jeopardize cycle life and safety. Whereas uncompromising cycle life and safety comes at the cost of lower energy density and weaker competitiveness. Most companies aim for a balanced sweet spot.

Cell manufacturers often tout cycle life figures of 6,000, 8,000, 10,000 even 18,000 based on specific controlled test conditions and model extrapolation. But actual cycle life is lower when cells are packaged into battery packs and deployed in energy storage systems. We expect a lifespan of about 3-18 years depending on the Depth of discharge, C rate, thermal and Battery Management put into place by each individual builder. That is a significant difference, because batteries are not invincible, but LiFePo4 is really versatile.

The 280Ah cells released in 2020 were produced by less than three manufacturers in 2021. Becoming mainstream in energy storage power stations in 2022, failure rate issues can be expected to surge around 2025 after initial installations complete their lifespan. Time will tell.

Safety Depends on Multiple Factors

Larger cells are a double-edged sword – cost reduction and accelerated market growth come with technical challenges and safety concerns. At the system level, safety depends on factors including cell design, thermal propagation isolation, early warning systems, fire prevention systems, and more.

Looking narrowly at the cell perspective, rising manufacturing automation enables producers to strengthen quality control capabilities. Meanwhile, breakthroughs in automated inspection equipment and methodologies screen cell safety before leaving factories.

Advancements in materials such as more thermally/chemically stable membrane systems and additives will also continuously improve battery safety and stability. But from an electrochemical standpoint, absolute safety remains elusive for lithium-ion batteries given inherent risks requiring mitigation through system design, monitoring, emergency response, and other management strategies. Therefore, a systematic approach will define future safety design.

Ultra Low Voltage Electrical Safety: Ensuring Safe Work Practices

Introduction

Electrical safety is a top concern in both industrial and residential environments. With the increased use of low voltage and ultra-low voltage (ULV) systems, it is essential to understand the safety measures required to prevent accidents and injuries. This blog post will discuss ultra-low voltage electrical safety, including the definition of ultra-low voltage, the benefits of using ULV systems, potential hazards, and best practices for ensuring safety.

What is Ultra Low Voltage?

Ultra-low voltage (ULV) refers to electrical systems that operate at or below 50 volts of alternating current (AC) or 120 volts of direct current (DC). These systems are designed to minimize the risk of electrical shock while still delivering adequate power to devices and appliances. ULV systems are commonly used in applications such as lighting, telecommunications, and control circuits, as well as in consumer electronics like laptops and smartphones.

Benefits of Using Ultra Low Voltage Systems

  1. Reduced risk of electrical shock: ULV systems significantly reduce the risk of electrical shock, as the voltages involved are much lower than those in conventional electrical systems. This makes ULV systems ideal for applications where the risk of electrical shock must be minimized, such as in medical equipment and devices.
  2. Energy efficiency: ULV systems are more energy-efficient than traditional electrical systems, leading to reduced energy consumption and lower utility bills. This is especially important in today’s world, where conserving energy and reducing greenhouse gas emissions are critical.
  3. Compact design: ULV systems generally require less space than conventional electrical systems, allowing for more compact and lightweight device designs. This is particularly beneficial in applications such as portable electronic devices and space-constrained installations.

Potential Hazards of Ultra Low Voltage Systems

While ULV systems pose a reduced risk of electrical shock, they are not entirely risk-free. Some potential hazards associated with ultra-low voltage electrical systems include:

  1. Fire hazards: Poorly designed or improperly installed ULV systems can generate heat, which may lead to a fire if not adequately managed.
  2. Electromagnetic interference: ULV systems can emit electromagnetic radiation, which can interfere with nearby electronic devices or communication systems.
  3. Component failure: Like any electrical system, ULV components can fail, leading to the malfunction or loss of functionality of the connected devices.

Best Practices for Ultra Low Voltage Electrical Safety

To ensure the safe operation of ULV systems, it is essential to follow these best practices:

  1. Training and awareness: Ensure that individuals working with ULV systems have received proper training in electrical safety, and are aware of the potential hazards associated with these systems.
  2. Installation and maintenance: ULV systems should be installed and maintained by qualified professionals, following the manufacturer’s guidelines and local electrical codes.
  3. Inspection and testing: Regularly inspect and test ULV systems to ensure their proper function and to identify any potential issues before they become critical.
  4. Proper grounding: Grounding is crucial for any electrical system, including ULV systems. Ensure that all grounding connections are secure and that grounding conductors are appropriately sized.
  5. Use of appropriate components: Always use ULV-rated components and devices when working with ULV systems, and ensure that they are compatible with the specific voltages and currents of the system.
  6. Labeling: Clearly label ULV systems and components to ensure that individuals working with or near the systems are aware of the voltage levels and any associated risks.

Conclusion

Ultra-low voltage systems offer many advantages in terms of safety and efficiency. However, it is crucial to be aware of the potential hazards associated with these systems and to follow best practices to ensure their safe operation. By implementing proper training, installation, maintenance, inspection, and labeling, ULV systems can provide a safe and efficient

Hithium 280ah 12000 cycle LFP cells used in 400MWh The largest standalone battery storage project in China

The 200MW/400MWh battery energy storage system (BESS) is live in Ningxia, China, equipped with Hithium lithium iron phosphate (LFP) cells.

Established 3 years ago in 2019 is already ramping up to a target of more than 135GWh of annual battery cell production capacity by 2025 for a total investment value of about US$4.71 billion.

The project was connected to the grid earlier this month, through a system integrator called ROBESTEC, about which little information appears publicly available. However, it is understood that although Hithium makes and provides complete BESS solutions as well as cells, in this case, it was the cell supplier.

200MW/400MWh HITHIUM LFP BESS in China

China 400MWh Hithium 12000 cycle LFP Battery 1

The facility stores energy at times of abundant generation from solar PV and wind, putting it into the grid during times of peak demand. It will also help regulate grid frequency.

If you are interested in these new 280AH cells, which Hithium and CATL currently can produce specifically for ESS use, let us know, as we have access to the cells when the demand is slightly lower. As these are actually in high demand for commercial applications, and they technically are hard to get for the DIY community.

it’s expected this giant LFP battery will cut CO2 emissions by 501,000 tons per year

Hithium specializes in the R&D, production, and sales of LFP energy storage batteries and systems. With strong customer orientation, they are committed to providing safe, efficient, clean, and sustainable energy storage solutions for the world. Hithium now has over 4400 employees globally including over 1000 R&D engineers with extensive experience in energy storage. With a planned 4.71 billion USD total investment and 1,400,000m2 factory space to achieve 135GWh production capacity of the energy storage battery in 2025.

Next-Generation Automotive M3P Batteries by CATL

CATL, the world’s largest Lithium Battery Manufacturer, has recently announced a new battery type, with a modified version of the LMFP chemistry, LMFP stands for Lithium Maganese Ferro Phosphate, its very similar to the LFP (LiFePo4) chemistry only that the manganese allows for the voltage to rise from the 3.2 to around 4.1v, this means there is higher energy inside the same form factor or another way to say that is the higher energy density.

CATL doesn’t do things unless they are tested, thought out, and ready for mass production.

Why Voltage matters

My two cents, what do we know about voltage and the effect it has on every type of Lithium Battery cells?

We know that the lower the nominal and fully charged voltage the longer the lifespan, if you look at LTO (Lithium Titanium oxide aka Li2TiO3) the nominal voltage lies at 2.3v and the lifespan can reach 20000 cycles with the fully charged voltage at only 2.8v.

Or if we look at what’s called ternary lithium cells, such as NMC (Lithium Nickel Manganese Cobalt Oxide aka LiNiMnCoO2 and NCA (Lithium Nickel Cobalt Aluminum Oxide aka LiNiCoAlO2) chemistry, the ones currently used by most Tesla’s (excluding the Chinese made Tesla’s that are not performance models) the nominal voltage is 3.7, but the full charged voltage is 4.2v, which is high, and it’s known that higher voltages translate into lower lifespans, which is why LFP does pretty well and can reach 6000 or even 10,000 cycles if treated well. It is also reported that Tesla will be one of the largest customers of CATL for the new M3P battery, with reports that the Tesla Semi will also use them.

So with rumors of the new M3P battery being manufactured by CATL, what have they managed to do, that gives a lifespan similar to LFP but still with the higher operating voltage? At this point we don’t know, as the information is not known, at least from my research I can’t find any further details on what they have added to the chemistry to enable the lifespan such as LFP.

According to CNEVPost, the M3P cells use the same olivine structure as LFP batteries. However, they replace iron with magnesium, zinc, and aluminum. There is speculation as to whether the Chinese website meant manganese instead of magnesium, but the information has not been corrected according to Autoevolution, so we are left to speculation.

Official data shows that the energy density of the CATL (LiMnZnAl) batteries will be about 15-20% higher than that of the LFP types, which hovers around 210 kWh/kg. This is a huge increase, and it’s believed it’s at a similar cost as the LFP battery.

It is also reported that Sunwoda and Eve Energy are all in the early stages of producing LMFP, with samples already being delivered to their partners for testing.

At this stage, we believe at first it will be very hard to get your hands on these cells, so I would estimate 2024 or even 2025 before this cell could be used for energy storage like we do today with the LFP cells.

And we still believe that LFP will have a longer lifespan, simply because of the voltage. We also now recommend a 90% DOD charge profile. 2.8v bottom and 3.45v top for your battery pack. We also believe keeping the draw at under 0.5C is a really good idea if you are wanting to achieve the huge cycle numbers and still have a good battery a few years from now.
