Storage capacity deterioration prevention and regeneration of secondary battery and storage capacity measuring device

Abstract

Due to the increase in the number of discharge times of the secondary battery, the surface of the battery electrode is covered by a thin film that is a poor conductor and an inactive substance. The film crystallizes over time, and the crystallization cuts off the charging path of electrochemical decomposition generated by the charging current. The positive and negative electrodes are not regenerated by recharging, and the power storage capacity deteriorates. Techniques for preventing degradation due to such a cycle life and performing regeneration are required, and full charge termination and remaining power storage information are required for energy efficient use of secondary batteries. To provide a device that regenerates the deactivated coating of electrode insulators based on charge and discharge, which is the cause of the deterioration of the storage capacity of secondary batteries, through the thermomechanical effect caused by dielectric relaxation loss, and automatically searches for the increase in the high-frequency dependent charge current For each dielectric relaxation loss frequency of a general secondary storage battery, the insulating coating is selectively decomposed, and the charging termination of the battery is known by disconnection and connection of the dielectric relaxation loss frequency, and the dielectric relaxation loss frequency is provided. Current conductance as the storage capacity of the state of charge.

technical field [0001] The present application relates to a device for preventing and regenerating secondary battery deterioration, using the dielectric loss frequency of the inactivating material to conduct dielectric heating miniaturization for the generation of electrode non-conducting inactivating materials based on discharge, and performing electric charging by charging current. Apparatus for chemically decomposed battery regeneration, involving both the dielectric dipole amount and the dielectric loss peak frequency due to the resulting dielectric heating current value imparted to the storage capacity, i.e. due to the amount of electrode non-conductor inactivating substances proportional to the discharge capacity The conductance is proportional, so the discharge amount can be known, and the current discharge amount is subtracted from the rated storage amount to know the storage amount as the state of charge SOC. Background technique [0002] Due to the increase in the ...
