Best top 5 300Ah energy storage cell companies in China

Looking at the development trend of the energy storage industry, the pursuit of larger battery capacity seems to have become the "standard configuration" of technology competition. Since last year, the pursuit of large-capacity batteries in the field of energy storage has become a trend.

According to statistics, more than 20 types of 300Ah energy storage cells have been released in the field of energy storage. At present, more than half of the cell manufacturers have 300Ah and above capacity cells, and the size of the cells is still 71173. This article sorts out the top 5 300Ah energy storage cell companies in China, including HiTHIUM, REPT, FEB, Higee and GREAT POWER, in no particular order.

1. Top 5 300Ah energy storage cell companies in China list

① HiTHIUM

HiTHIUM 320Ah battery is expected to cycle to 70% EOL up to 10,000 times according to the reliability model, and has obtained GB/T36276 certification in March 2023. The HiTHIUM 320Ah special battery for electric energy storage will be sampled globally in the third quarter of 2023 and delivered globally in the first quarter of 2024.

② REPT

REPT is mainly engaged in the R&D, production and sales of lithium-ion batteries, providing solutions for new energy vehicle power and smart energy storage.

REPT launched a new generation of energy storage cells in September last year - 320Ah energy storage cells, which will be officially launched in Q2 2023. Since 2022, REPT's shipments of energy storage cells have been rising steadily, and it will rank among the top three in the global energy storage battery list in Q1 of 2023, and it has realized the supply of cells to POWIN, an American system integrator.

③ FEB

FEB's main business covers energy storage, light travel, electric tools, smart home and other sectors, and is committed to becoming the world's leading service provider of lithium batteries (including lifepo4 battery and ternary lithium battery) and energy storage systems. The company is a vertically integrated manufacturer with core production links such as lithium batteries, modules, and system integration.

FEB 305Ah batteries will be mass-produced in August-September this year, with a planned capacity of 5GWh and a size of 71173. This product uses a composite conductive agent combining point, line and surface and an exclusive self-developed electrolyte formula, which has the advantages of long life, low temperature resistance and high cost performance.

The rated capacity is up to 305Ah, the weight specific energy is ≥180Wh/kg, the volume specific energy is ≥383Wh/L, the normal temperature cycle life is up to 10,000 times, and the high temperature cycle is up to 5,000 times. At the same time, it can meet the charging at -10°C and fully reduce the energy consumption of battery heating or environmental temperature control.

④ Higee

Higee is mainly engaged in the R&D, production, sales and service of lithium-ion batteries, battery packs and systems for energy storage. The product is positioned in the field of energy storage applications, and its downstream applications cover multiple application fields such as large-scale containerized energy storage systems, industrial and commercial energy storage products, household energy storage equipment, and communication backup power.

In February, Higee launched a 375Ah large-capacity energy storage cell, which adopts a laminated winding process, has a capacity of 1.2KWh, exceeds 10,000 long cycles, and is compatible with 0.5Cp and 1Cp operating ratios.

According to the parameters released by Higee, the heat dissipation area of the product has increased by 106%, and there is no need for a liquid cooling design, and the traditional forced air cooling can meet the needs of use. The number of system parts is reduced by 30%, the production efficiency is increased by 25%, the volume utilization rate is increased by 16.5%, the 40-foot container can accommodate up to 7MWh, and the overall total cost is expected to be reduced by 9%.

⑤ GREAT POWER

GREAT POWER is one of the top 10 energy storage lithium battery companies in China. It provides batteries, packs, battery clusters and other products, which are used in power generation and grid energy storage, industrial and commercial user-side energy storage, UPS communication base station backup power supply, household energy storage & portable energy storage.

GREAT POWER 320Ah energy storage cell, compared with the previous generation of cell products, the single capacity has increased by 14%, and the system energy has increased by 14% in the 280Ah cell with the same size (71173), its cycle life is >8000 times, and its service life exceeds 20 years. At the same time, it has excellent performance in low temperature capability, which can satisfy storage at -40°C and discharge at -30°C.

2. Conclusion

Besides these top 5 300Ah energy storage cell companies in China, there are a lot of other 300Ah energy storage cell companies and other large capacity energy storage battery cells. The choice of company and energy storage battery cells depends on the needed applications.
