Electrode for lithium secondary battery

摘要

An electrode for lithium secondary batteries comprises an active electrode material and a binder consisting of a bis-allyl-nadi-imide or allyl-nadi-imide compound, i.e. a water-dispersible, addition-polymerisable, low molecular weight imide monomer. Independent claims are also included for (a) the production of the electrode by coating the surface of a collector with an aqueous slurry containing powdered electrode material and binder, drying the mixture and heating at 100-500 deg C for 1 hour or more; and (b) lithium secondary batteries with the above components, particularly batteries in which the same type of imide-based binder as above is used for both the cathode material and the anode material.
