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.

  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

Game Changer : Diesel vs Electric Trucks

Thanks to the Fully Charged YouTube channel and an innovative Australian company, you will finally have some really good evidence to tell all your friends. Why an Electric Truck is better than Diesel.

Don’t have time to watch a full YouTube video? Here is a summary

Janus Trucks – Janus Electric based in NSW is doing Electric Truck conversions.

90+ Tonne Rated – Twice the ability of the Tesla Semi
720HP – 540Kw Electric Motor
Uses the Original Transmission
RE-GEN Braking
1.5-1.7Kwh per Kilometer
Battery Pack Size – 620Kwh – Equivalent to 8 Tesla Model 3 vehicles

Removes 3.5 Tonnes of existing Motor and other parts.
Add 4 Tonnes for Motor, Battery and Drivetrain

Electric Truck Cost – 60cents a Kilometer at Grid Pricing
Can be as low as 6 cents a Kilometer from your own Solar installation.
Diesel Truck Cost – $1- a Kilometer
THAT is up to 18 times cheaper than Diesel

Maintenance Costs are vastly reduced. As low as 4 cents a Kilometer
Multi Million Kilometer Lifespan for the Electric Motor
Gearbox – reduced vibrations and other wear and tear, expecting double the lifespan when using Electric motor vs the diesel.

The Motor can REGEN up to 540kw of power when Braking.

No Pollution in Urban area’s

Total cost is only $150,000-$170,000 when battery is AS A SERVICE model. That mean’s they pay to rent the battery per Kilometer

After the battery has reached 80% of original capacity it can then be used for storage applications such as on and off grid commercial, or housing applications.

Are second life Lithium Batteries safe?

Are you considering repurposing battery cells and building your own Powerwall or similar Energy storage system?

We are going to take a look at what you must understand before starting a project of this type.

The Chemistry

NMC or NCA

Both of these chemistries are considered dangerous, and they should be avoided, especially in any second life application. And even more importantly in any residential application. There is a real risk of a short circuit, leading to thermal runaway. Both of these chemistries will be extremely difficult to extinguish. And may explode, and burn anything and everything around it down to ashes, Firefighters will not try to extinguish a Lithium Battery fire, as they know they have no option but to wait for the

The capacity loss of LiBs is generally considered to be linear, with end of life typically around 75% to 80% state of health (SoH) and the final end-of-life stage around 50% to 60% SoH. However, at some point a severe and potentially dangerous deterioration can occur and lead to an increased ageing rate. The time at which this occurs, referred to as the “knee,” is difficult to predict. It can occur at a higher SoH than expected, thereby increasing the risk of thermal runaway, internal short circuits, and joule heating, according to the report.

Lithium Iron Phosphate

Although it is possible for LFP to enter thermal runaway, it is very unlikely, and usually only happens when external heat is present, it can also happen when the cell is at 100% SOC and is supplied with a very high current, such as

News Sodium Ion
The Sodium Ion Battery is here

CATL the world’s largest Lithium battery manufacturer is now manufacturing the Sodium Ion Battery cell. It has the same energy density as LFP at 160Wh/Kg, however it’s even safer, and eventually it will be cheaper to manufacture due to not needing the expensive Lithium. And it wont require expensive shipping options to get to the end user, as it wont be a class 9 Dangerous Good.

Although it won’t be available to purchase until at least 2025. It is here, and it will likely be the Battery technology of choice for ESS. Such as homes, RV, and other similar use.

We see LiFePo4 being the dominant battery choice for the majority of users until late in the decade. The demand for Sodium Ion batteries will be very high, and although CATL has designed the battery to be able to be manufactured with the majority of the same machines and factory lines, it will still take a number of years for other companies to catch up to CATL. There are a number of companies already also manufacturing Sodium ion batteries. Which we will cover soon, and we will likely be posting more and more about this ground-breaking battery technology.
