Title:
NOVEL BATTERY CAPACITOR BASED ON COMPOSITE ANODE AND CATHODE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/110134
Kind Code:
A1
Abstract:
The present invention relates to the field of novel energy resource storage devices, and particularly to a novel battery capacitor based on a composite anode and cathode material. The battery capacitor comprises an anode, a cathode, a conductive agent, a bonding agent, an electrolyte, a separator membrane and an etched aluminum foil sheet; and the anode of the battery capacitor is made of a composite material comprising lithium manganite and activated carbon, and the cathode of the battery capacitor is made of a composite material comprising lithium titanate and activated carbon. The present invention employs lithium manganite and lithium titanate composite electrodes, thus greatly improving the conductivity of an electrode material and an energy storage performance of a part of the capacitor by introducing activated carbon, significantly improving the rate performance of a product, and satisfying requirements for large current charging and discharging; through the doping and coating of lithium manganite and lithium titanate, the problems of gas production and dissolution are solved, and a cycle lifespan is improved; in addition, through the use of the composite conductive agent, a better conductive network can be constructed, and a power density can be further enhanced.
