Claims (1)
- 電池缶内に、充電時の開路電圧がLi基準で4V以上を示すリチウム含有複合酸化物を正極活物質として用いた正極と、結晶の(002)面の面間距離(d002)が0.350nm以下である炭素材料を用いた負極とがセパレータを介して渦巻状に巻回されてなる電極体を備え、該電極体の中心空隙部に中空筒状のセンターピンを収容してなる非水二次電池において、
前記センターピンは金属材を筒状加工したもので、その軸方向に沿って延びる金属材両端面が隙間を介して対向もしくは近接したものから構成されており、
前記両端面の近傍には、当該両端面を前記センターピンの内側に折返し加工することによって角落とし部が設けられていることを特徴とする非水二次電池。
