Top Ten Manufacturers of Energy Storage Large-capacity battery cell 3.0 era is approaching
2022-01-09
1.Hithium 1175Ah
1175Ah, as a battery designed for 4-8 hours of long-time energy storage, has four major advantages: large capacity, long life, high safety and low cost.
It fills the gap of the lack of specialized batteries for medium- and long-term energy storage, and also sets a new upper limit for the capacity of a single cell in the industry. For downstream customers in the energy storage industry, this cell will greatly reduce the number of large-capacity long-duration power station management cells, simplify the difficulty of operation and maintenance, and reduce system costs.
2.CATL 587Ah
The 587Ah cell takes into account the optimal balance between station matching, system integration, and electrochemical characteristics. CATL points out that the use of CATL 587Ah batteries and integration in energy storage projects can further optimize the “kWh cost” and bring higher returns for project investment.
In terms of size design, the 587Ah embodies a scientific balance: the height realizes the best combination of energy density and service life; the width ensures the uniformity of current distribution and improves product reliability.

3.REPT 392Ah
Compared with the 500+Ah mega-capacity cell, the 392Ah energy storage cell is more balanced in terms of safety, manufacturability, long life, high energy density and low cost, and is one of the products with better overall performance at this stage: the high compatibility of the production line process strongly guarantees rapid mass production.
Among the 300+Ah series, the 392Ah energy storage cell has very small size change, strong compatibility, low transformation cost, short cycle and fast production ramp-up, which is the new generation of energy storage cells that can realize mass production in the industry at the fastest pace, and can meet the market's urgent demand.
It not only has a long cycle life and high energy efficiency, realizing long-lasting range and efficient conversion, but also enjoys high energy density and safety and reliability, with excellent thermal runaway protection.
4.Svolt 770Ah
770Ah upgraded the traditional stacking process into a "3D printing" mode, with the third generation of stacking machine, the production efficiency directly take off the cycle life of up to 10,000-15,000 times, energy density is further enhanced to 435Wh / L.
The key is to solve the production of large-size battery cells, yield rate is guaranteed at the same time.
5.AESC 500Ah+
A new generation of battery cell products with RTE of 96%, energy density of 440+Wh/L, and more than 15,000 cycles.
The high energy density energy storage cell combined with the intensive system design allows AESC 8MWh+ energy storage system to reach an energy density of 541kWh/㎡ per unit area, setting a new record in the industry.
6.Narada 690Ah
Compared with the 280/314Ah battery solution common in the industry, Narada's 690Ah ultra-large energy storage battery realizes cost reduction and efficiency in three dimensions: cell, system, and manufacturing, which improves the overall benefit of the energy storage project.
At the battery level, the number of structural parts such as battery shells and foils of Narada's 690Ah ultra-large energy storage battery can be reduced by 50%, and the stacking efficiency can be increased by 150%;
From the system design point of view, due to the significant reduction in the number of batteries connected in series and parallel, the number of system electrical connection parts can be reduced by 50%, which is compatible with capacities ranging from 650Ah to 750Ah. The capacity of a 20-foot energy storage system equipped with this battery can reach 6MWh.
7.Cornex 688Ah
The actual volumetric energy density exceeds 430Wh/L, the energy efficiency can reach 95%~96%, the cycle life is expected to exceed 10,000 weeks, and the safety tests such as thermal runaway, shallow puncture, and overcharging have all been passed.
Compared with the current mainstream 314Ah energy storage cell, 688Ah cell adopts advanced material technology and manufacturing technology in the industry, the capacity of single cell is increased by 119%, volumetric energy density is increased by 7.5%, the cost of cell is expected to be reduced by more than 6%, and the capacity of 20-foot single-compartment energy storage system is increased by 37.6% to 6.9MWh, and the system cost can be further reduced.
8.Gotion 688Ah
The energy density of the cell is up to more than 435Wh/L, compared with the current mainstream 314Ah cell. The performance has been significantly improved, and the capacity of a single cell has reached 2.2 degrees of electricity, with a cycle life of more than 10,000 times and a calendar life of more than 20 years.
The 20-foot standard cabin equipped with 688Ah cells can increase the system capacity to more than 6.9MWh, which can save about 20% of floor space, reduce the number
