Hitachi has developed capacity recovery technology to extend the service life of Lithium-Ion Batteries (LIBs) built into power storage systems in a non-destructive manner. This innovation promotes a shift to mainly renewable energy power sources for power systems and a transition to electric mobility.
Battery capacity can be recovered though reactivation of the lithium ions not contributing to battery charge and discharge, by combining battery diagnostics and electrochemical process
During the aging process of the LIBs, the phenomenon of capacity recovery will occur if the battery is standing for too long. Existing SOH estimation methods based on neural network do not propose countermeasures for the phenomenon, but in fact, capacity recovery is inevitable and it has a great impact on SOH estimation.
Service life refers to the lifespan until the LIB capacity drops below the capacity requirements of a power storage system. In this research, the capacity requirement as a remaining capacity which is 80% of the initial capacity is defined.
Using a 5-second pulse, we achieved >30% of capacity recovery in both Li-Si and Si–lithium iron phosphate (Si-LFP) batteries. The recovered capacity sustains and replicates through multiple pulses, providing a constant capacity advantage.
