Maxell Has Elucidated the Capacity Degradation Mechanism to extend the Life of All-Solid-State Batteries
Development of All-Solid-State Batteries with Superior Safety and Reliability for the Realization of a Sustainable Society
Maxell’s detailed analysis of the capacity degradation mechanism of all-solid-state batteries has elucidated that their materials themselves hardly degrade, and that the main cause of the capacity reduction is the SOC (State of Charge) imbalance between the electrodes. Additionally, the experiments using symmetric cells have successfully quantified the electrode-specific side-reaction rate, demonstrating that the side-reaction current in all-solidstate batteries is more than one order of magnitude lower than that in liquid-based batteries. In other words, it has become clear that the inherently superior lifetime characteristics of all-solidstate batteries can be attributed to the extremely low side-reaction current in the electrodes.
