This video made in 2023, shows the EVE factory, with some of its most advanced manufacturing equipment in full operation. We are see in the space of just 4 or 5 years, the speed and yield has increased dramatically. The combination of many technologies has increased the lifespan of a LFP cell.
We currently recommend the use of the MB30 and MB31 cells for 300+ah cells. They are the most advanced cells for Energy Storage made by EVE.
EVE makes more than 50 cells that I am aware of, probably more than 100 if you include some of the lesser known cell types and variants.

One of the best videos we have ever seen to explain what is really happening in the newest generation of LFP cells is this one made by CATL in 2024.

https://youtu.be/0cyz5vXd-xY – It was made private by CATL recently on their YOUTUBE channel. We found a copy of the video in the wayback machine. And though its low resolution, Its still good enough to see the tech in laymans terms.

EVE Lithium LFP Cells List 3.2v

A list of cells manufactured by EVE in July 2024.
It details the capacity, energy density, estimated cycle life, weight, and Internal resistance of each cell.

Using this information you might be able to decide what cells suit your application best.
For example the LF50k cell is rated for 7000 cycles at 1C charge and discharge. But its energy density is very low. The main reason it gets such a good rating is because it can be actively cooled or heated in the right application, which can help tremendously with lifespan.
However you will also note that cycle life is now mostly spoken about at 0.5C or P. Meaning much of the information previously released has been further corrected over time.
All of these numbers are best case scenario, and usually at 25 degrees Celsius. So these numbers are basically unattainable in most cases.

The company focused on developing and producing batteries for Nissan’s electric and hybrid vehicles, such as the Nissan Leaf, using innovative materials to increase energy density and decrease cost. [1] [2]
In 2018, Nissan sold its battery businesses, including AESC, to Envision Group, a Chinese renewable energy company that also owns Envision Digital, a global leader in AIoT (artificial intelligence of things) solutions. Envision Group renamed AESC as Envision AESC and acquired the 49% stake held by NEC. The deal was valued at around $1 billion. [3] [4]
Envision AESC has four battery production plants around the world: in Zama, Japan; Sunderland, UK; Smyrna, USA; and Wuxi, China. The company also has two R&D centers in Japan and the USA. The company employs around 5,000 people globally and has an annual production capacity of 7.5 GWh. [5] [6]
Envision AESC’s batteries use a lithium manganese oxide (LMO) chemistry with a manganese spinel cathode, which offers high power density, long cycle life, safety and low cost. The company also uses laminated cells, which have better thermal management and packaging efficiency than cylindrical or prismatic cells. The company’s flagship product is the Gen5 battery, which has a gravimetric energy density of 265 Wh/kg and a volumetric energy density of 700 Wh/L. [7] [8]
Envision AESC’s vision is to turn electric vehicles into green mobile personal energy sources that can participate in the renewable energy eco-system. The company leverages Envision Group’s AIoT platform, EnOS, to connect its batteries with smart grids, smart charging networks, renewable energy sources and other devices. The company aims to create a dynamic balance between supply and demand of clean energy and enable vehicle-to-grid (V2G) and vehicle-to-home (V2H) applications. [9] [10]
Envision AESC is also working on developing next-generation batteries that can offer higher energy density, lower cost and longer range for EVs. The company expects to start producing batteries that can give EVs a range of at least 1,000 km (620 miles) in 2024. The company also plans to expand its production capacity to 30 GWh by 2025 and 110 GWh by 2030. [11] [12]
Envision makes a 300ah LFP format cell named the Envision 305 which has been for sale in 2023 for about $75USD wholesale.

Envision AESC is a battery technology company that has a rich history, a global presence, a unique chemistry, a visionary strategy and an ambitious roadmap. The company is poised to play a key role in the electrification of mobility and the decarbonization of energy.
