Electrode material containing polyvinyl alcohol as binder and rechargeable lithium battery comprising the same
Provided is an electrode mix for a secondary battery containing an electrode active material, comprising a PVA having a degree of polymerization of more than 2500 and a degree of saponification of more than 90% as a binder, and a lithium secondary battery comprising the same. Use of the binder according to the present invention can provide advantageous effects such as improved adhesive strength between the electrode mix and current collector and between the electrode mixes, prevention of the peeling and separation of the active material even after repeated charge/discharge cycles, and inhibition of decreases in the capacity or output power retention rate of the secondary battery.
