With the popularization of renewable energy and the rapid development of distributed energy systems, energy storage technology is increasingly receiving global attention. According to data from GGII, the penetration rate of 280Ah battery products in China's power storage projects has exceeded 80% in 2022. In the second half of 2023, most energy storage companies will launch high-capacity battery cells with a capacity of 300+Ah or more, and achieve mass production and delivery, officially launching a race for high-capacity battery cells.

However, Ouyang Minggao, an academician of the CAS Member, mentioned that the 300+Ah high-capacity lithium iron phosphate energy storage cell has certain hidden dangers in intrinsic safety. The safety accidents of energy storage power stations that occurred in many parts of the world this year have once again attracted people's attention. In the field of energy storage, the safety performance of battery cells has become the foundation of all performance.

 

Great Power's 314Ah large energy storage cell, with its outstanding safety technology innovation, has set a new safety benchmark for the energy storage industry. This 314Ah large storage battery cell has excellent safety performance and has passed more than 20 safety regulations tests such as needle puncture, thermal runaway, impact, and injection. Moreover, it does not experience thermal runaway even under overcharge conditions.

 

This 314Ah large storage battery cell has a stable system, safe and reliable quality, and meets certification requirements such as UL1943, UL9540A, IEC62619, UN38.3, ROHS&REACH, etc. In terms of materials, advanced nano coating technology is also adopted, greatly improving the strength of the electrode and separator, ensuring the stability of the battery. In addition, the realization of in-situ gel of electrolyte makes the 314Ah large storage core form a safe and stable interface between the positive and negative electrodes and electrolyte, effectively avoiding the occurrence of thermal runaway.

 

 

The mass production of Great Power's 314Ah large storage battery cells has further promoted the development and application of 300Ah+large capacity battery cells in the industry, providing better battery cell solutions for large-scale energy storage scenarios.
