Provided is an apparatus in which an electrode insulation inactivating layer on the basis of charge and discharge which is a cause for deterioration of storage capacity of a rechargeable battery is regenerated by thermo-mechanical effects caused by dielect...

A system for removing a layer of lead sulfate insulation crystals in which lead sulfate is selectively subjected to heating by dielectric relaxation loss at a peak frequency of lead sulfate dielectric relaxation loss of 10 MHz, thereby finely decomposing t...
