Battery active material powder mixture, electrode composition for batteries, secondary cell electrode, secondary cell, carbonaceous material powder mixture for electrical double-layer capacitors, polarizable electrode composition, polarizable electrode, and electrical double-layer capacitor

摘要: An active material powder mixture for batteries or a carbonaceous electrical double-layer capacitors is composed of battery in combination with an electrically conductive that adheres to the periphery and has average particle size 10 nm μpm. The may be used make electrodes secondary batteries. polarizable capacitors. Secondary cells produced using can lower impedance electrode operate at high capacity current, have rate property, are thus well-suited use as lithium ion cells. Electrical made output voltage because low impedance.
