The Chinese battery manufacturer and technology company CATL launched TENER – the first energy storage with zero degradation over the first 5 years of operation. It is also described as the world’s first mass-producible energy storage system with zero degradation in the first five years of use. Hence, the company managed to create an “ageless” energy storage unit.
The battery is positioned in a 20-ft-equivalent container and has a capacity of 6.25 MWh. Hence, the TENER is similar to Tesla’s Megapack, which is also positioned in a metal box. According to reports, CATL managed to achieve 30% more energy density per unit area in comparison to previous versions. The batteries used utilize lithium iron phosphate (LFP) chemistry, resulting in an energy density of 430 Wh/L, which is significantly higher than the typical industry range.
It is also reported that the number of charge/discharge cycles exceeds 15,000, resulting in an estimated 20 years of operation. Moreover, estimated is also a 20% reduction in the overall station footprint. Zero degradation is achieved through the utilization of biomimetic SEI (solid electrolyte interphase) and self-assembled electrolyte technologies, which enable the movement of lithium ions without roadblocks.
Furthermore, via a quality management system, the company has achieved the ultimate safety of energy storage systems. This system includes technology development, proof testing, operation monitoring, and safety failure analysis.
However, the price of the energy storage unit is still not revealed.
CATL (Contemporary Amperex Technology Co., Limited) was founded in 2011 and is headquartered in Ningde, China. The company is the biggest manufacturer of lithium-ion battery cells in the world.
