摘要：
A positive electrode plate (11) includes a current collector (30) and a mixture layer (31) disposed on the current collector (30). The mixture layer (31) has a thin portion (32) with a thickness of less than 200 μm disposed on an inner coil half of the current collector (30) and a thick portion (33) having a larger thickness than the thin portion (32), the thick portion (33) having a yield loop height H measured by a stiffness test of 6 mm
