CATL launches energy storage system with ‘zero degradation in first five years’

April 17, 2024

Chinese battery manufacturer CATL has launched what it says is the world’s “first mass-producible energy storage system with zero degradation in the first five years of use”.

The system called ‘TENER’ has a capacity of 6.25 MWh will “accelerate large-scale adoption of new energy storage technologies as well as the high-quality advancement of the sector,”the company said.

A CATL statement added: “Leveraging biomimetic SEI (solid electrolyte interphase) and self-assembled electrolyte technologies, TENER has cleared roadblocks for the movement of lithium ions and achieved zero degradation for both power and capacity, ensuring zero growth of auxiliary power consumption throughout full life cycle, thereby creating an ‘ageless’ energy storage system.”

Powered by cutting-edge technologies and extreme manufacturing capabilities, CATL has resolved the challenges caused by highly active lithium metals in zero-degradation batteries, which effectively helps prevent thermal runaway caused by oxidation reaction.

CATL says TENER’s 6.25 MWh capacity in the TEU [twenty-foot equivalent unit] container represents a 30 per cent increase in energy density per unit area and a 20 per cent reduction in the “overall station footprint, thus enhancing energy density and efficiency through innovative design within a limited space”.
