摘要:
To provide an electrode for a non-aqueous electrolyte secondary battery which retains the shape while retaining a discharge capacity at a high rate.
An electrode for a non-aqueous electrolyte secondary battery has a current collector and an electrode active material layer arranged on a surface of the current collector, and is used for a non-aqueous electrolyte secondary battery having a liquid volume coefficient of 1.4 to 2.0, in which the electrode active material layer includes an electrode active material and a binder including polyvinylidene fluoride (PVdF), and the polyvinylidene fluoride (PVdF) is in a non-crystallized state and is included in the range of 0.5 to 3.3% by volume with respect to the total volume of the electrode in the electrode active material layer.
