World first energy storage unit demonstrates zero degradation over 5 years
China's CATL – the world's largest EV battery producer – has launched TENER, which is described as the "world's first mass-producible energy storage system with zero degradation in the first five years of use."
TENER is a bit like Tesla's Megapack, in that it's a big battery pack housed within a metal box that's designed to store energy from intermittent renewables such as solar and wind. This is reported to translate into a 30% energy density increase per unit compared to previous iterations, which should mean a smaller footprint for new multi-unit installs or more juice for existing power stations. A platform to test the safety of its energy storage systems across different power grid setups has been developed, and will continuously monitor projects post-installation with the help of AI.
