Claim Text:
1. An apparatus for electrochemically removing an electrode non-conductor inactivating layer on the basis of charge and discharge which is a cause for deterioration of storage capacity of a rechargeable battery, comprising: a charging voltage detector; a charging current detector; a charging current breaker; a high-frequency variable oscillator; a high-frequency constant-voltage output electric power amplifier; and a high-frequency electric current detector and a high-frequency electric current breaker; and wherein a high-frequency alternating current at a frequency of dielectric loss in association with heat-generating effects caused by dielectric relaxation loss is applied to positive and negative electrodes of the rechargeable storage battery; wherein individual peak frequencies of dielectric relaxation loss of rechargeable batteries in general are automatically searched by an increase in high-frequency dependent charging current, thereby selectively decomposing an insulation layer; wherein a frequency of the high-frequency alternating current is found at a high-frequency band of ion diffusion current of the rechargeable battery which is equal to or higher than a response speed; wherein the apparatus outputs a remaining storage quantity which is a state-of-charge and a signal that indicates termination of complete charge when both at least one of a number of dielectric crystallization and a number of non-crystallization dipoles are zero in conductance; wherein the number of dielectric crystallization and non-crystallization dipoles, which is a quantity of electrode crystallization and non-crystallization non-conductor substances proportional to a discharge quantity, is proportional to conductance at peak frequencies of relaxation loss of both said at least one of the dielectric crystallization and said at least one of the non-crystallization dipoles, so as to correspond to a discharge quantity; wherein the discharge quantity at the present time is deducted from a rated storage quantity; and wherein the apparatus performs a method for intermittently modulating a continuous high-frequency electric current, thereby effectively imparting a thermo-mechanical impact to said insulation layer.
