According to statistics, the proportion of 280Ah large capacity square cells in the energy savings market has exceeded 80%. It is noteworthy that there are currently over 20types 300Ah energy storage battery cells available on the market.

More notably, in the competitive field of over 500Ah, EVE Lithium Energy has launched 560Ah energy storage cells, while VISION Group has developed 580Ah energy storage cells, demonstrating a strong competitive trend.

Last year, EVE Energy Storage released a 560Ah energy storage battery - LF560K, with a battery capacity of 560Ah and a single battery energy of 1.792kWh. LF560K is twice the common size of 280Ah square cells, equivalent to two 280Ah cells placed horizontally side by side, with a single cell weight of 10.95kg. Global delivery is expected to begin in Q2 2024.

2.2. VISION Shares 580Ah

5. Great PowerEnergy 320Ah

Compared to the previous generation of battery cells, Great Power Energy's 320Ah single cell capacity has increased by 14%. Among products with the same size of 280Ah battery cells (71173), the system energy has increased by 14%, with a cycle life of>8000 times and a service life of over 20 years. At the same time, it performs excellently in low temperature capacity and can meet the requirements of -40 ℃ storage and -30 ℃ discharge.

This new product has a volume energy density of 385Wh/L, 10000 cycles, and high compatibility (performance, size, and thermal management compatibility), which can significantly reduce the initial purchase cost and full lifecycle electricity cost of the system.

Through technological innovation, the new generation of 320Ah electric energy storage dedicated batteries are more suitable for the development model of the electric energy storage market in terms of cell cost, system cost, and full box standard configuration.

One of the star products of Hithium Energy Storage, the 300Ah electric energy storage dedicated battery has attracted attention for its excellent safety and reliability. Through unique technological innovation, this battery has maintained "zero" attenuation during the first 1000 charging cycles, with a cycle life of up to 12000 times. This ultra long lifespan not only reduces product costs throughout the entire lifecycle, but also brings significant benefits to customers.

This is a thousand ampere hour ultra large capacity battery specially designed for the long-term energy storage market, aimed at the trend of large-scale development of electric energy storage by Hithium Energy Storage.

The volumetric energy density of MIC1130Ah reaches 400Wh/L, an increase of over 15%, which can help reduce the cost of energy storage DC side systems by 25% (compared to 280Ah products). Simultaneously meeting the needs of ultra large capacity, ultra long lifespan, ultra-high safety, and ultra-low cost for long-term energy storage.

Last year, with a focus on reducing the cost of energy consumption (LCOS), we successfully developed a Trina chip with a long cycle life of 300Ah. In April of this year, we launched a new generation of 306Ah energy storage cells, which, through the collaboration of multiple technologies, further increased the cycle life of the cells to 12000 times.

Relying on its own energy storage battery research and development platform, Trina discovered 97.5% of the password for battery life decay during the self-developed battery cell process. That is, 97.5% of the cyclic decay of the battery cell is irreversible loss, and 97.5% of these losses come from active lithium loss.

The Far East Battery 305Ah was mass-produced from August to September this year, with a planned production capacity of 5GWh and a main size of 71173. This product uses a composite conductive agent that combines dots, lines, and surfaces, as well as an exclusive self-developed electrolyte formula. With the advantages of long lifespan, low temperature resistance, and high cost-effectiveness, it has a rated capacity of 305Ah, a weight to energy ratio of ≥ 180Wh/kg, a volume to energy ratio of ≥ 383Wh/L, a normal temperature cycle life of 10000 times, and a high temperature cycle of 5000 times. At the same time, it can meet -10 ℃ charging, fully reducing energy consumption for battery heating or environmental temperature control.

As an upgraded version of 280Ah energy storage cells, the 314Ah cells launched by Battero TECH New Energy are expected to be mass-produced by the end of September 2023, using a winding process. The actual capacity can reach about 330Ah, with a size of 71173.

It is revealed that the 314Ah battery cells of Battero TECH New Energy have passed multiple certifications. Battero TECH New Energy plans to build a new 45GWh battery production line and lithium-ion battery cell modules, with an expected annual output value of over 40 billion yuan after reaching production capacity.

CORNEX New Energy has established three major bases in Jiangxia, Yichang, and Xiaogan, Wuhan, and has started construction and production in stages. The total investment in the next few years will exceed 100 billion yuan, of which the fixed assets investment will exceed 50 billion yuan, and the planned total capacity will exceed 400GWh.

Gotion High tech has exhibited 300Ah energy storage battery cells, and currently, the order volume of Gotion High tech's 300Ah battery cells is relatively saturated. The size of Gotion High tech 300Ah energy storage battery cells is the 81 size series, which is different from the 71 size series that is currently popular in the energy storage market. The considerations mainly stem from the insistence on one's own technology, as well as its ability to co wire with 340Ah power cells.

Gotion High Tech stated that the current energy storage market is large enough and it is unlikely that one size can be unified. Gotion High tech will adhere to the 81 size series in the future, and the next generation of energy storage cells will reach at least 330Ah.

The upgraded version of 305Ah has a thickness that is half thinner than the first generation of 305Ah battery cells, and its length has doubled, forming a "long and thin" short knife shape. As of now, the annual production capacity has reached 12GWh, and 4GWh of energy storage projects have been put into operation worldwide.
