| abstract | The present application relates to a battery, comprising a positive electrode plate, a separator film, and a negative electrode plate. The positive electrode plate comprises a positive electrode current collector and at least two layers of positive electrode active material coated on at least one surface of the positive electrode current collector. A lower layer of active material contacting the positive electrode current collector comprises a first positive electrode active material, a first polymer material, and a first electrically conductive material. On the basis of the total weight of the lower layer of positive electrode active material, the first positive electrode active material content is A% by weight, the first polymer material content is B% by weight, and the first electrically conductive material content is C% by weight; an upper layer of positive electrode active material contacting the lower layer of positive electrode active material and away from the positive electrode current collector comprises a second positive electrode active material, a second polymer material, and a second electrically conductive material. On the basis of the total weight of the upper layer of positive electrode active material, the second positive electrode active material content is A'% by weight, the second polymer material content is B'% by weight, and the second electrically conductive material content is C'% by weight, wherein A％<A'％, B％>B'％, C％≥C'％, and the first polymer material comprises fluorinated polyolefin and/or chlorinated polyolefin polymer material. The battery has desired safety and improved electrical performance. |
