ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, METHOD FOR PRODUCING SAME, AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL

WIPO Patent Application WO/2011/033707

A1

Disclosed is a non-aqueous electrolyte secondary cell having excellent input/output characteristics and adhesion between an electrode mixture layer and a current collector. An electrode for the non-aqueous electrolyte secondary cell has a current collector and an electrode mixture layer adhered to the surface of the current collector; the electrode mixture layer contains a binding agent and an electrode active material containing a metal oxide; for every 100g of electrode active material, the oil absorption of the electrode active material is at least 25g and no more than 200g; and considering the thickness of the electrode mixture layer to be T, the quantity (W1) of binding agent in the region that is 0.1T in thickness from the surface side of the electrode mixture layer and the quantity (W2) of binding agent in the region that is 0.1T in thickness from the current collector side of the electrode mixture layer are such that 0.9 ≤ W1/W2 ≤ 1.1.
