Title:
セルロース系伝導性高分子を含む活物質組成物用バインダー及びこれから製造されたリチウムイオン電池
Document Type and Number:
Japanese Patent JP6980217
Kind Code:
B2
Abstract:
The present invention relates to an electrode active-material composition including, as a binder material for an electrode active material, a conductive polymer synthesized using a cellulose-based compound and/or a weakly acidic compound alone or in combination as a template, and a lithium-ion battery manufactured using the same, and particularly to PEDOT:CMC synthesized as a preferred active-material composition, and a lithium-ion battery manufactured using the same as a binder. The technique of the present invention is capable of improving the cycle characteristics, that is, the lifetime, of the lithium-ion battery including an anode active material made of a graphite component and/or a silicon component alone or in combination, along with various cathode active materials including a nickel-cobalt-manganese (NCM)-based active material, a nickel-cobalt-aluminum (NCA)-based active material, a lithium-cobalt oxide (LCO) active material, and other lithium.
