正极前体
Abstract:
一种正极前体，其包含正极活性物质和碱金属化合物，上述正极活性物质含有碳材料，其特征在于，将上述正极前体的每个单面的正极活性物质层中的碱金属化合物的基重设为A(g/m2)时，满足5≤A≤35，并且将上述正极活性物质层中的正极活性物质的基重设为B(g/m2)时，满足10≤B≤100，进而满足0.20≤A/B≤1.00，并且，将上述正极前体的每个单面通过BET法测定的单位面积比表面积设为C(m2/cm2)时，满足1≤C≤20。
Abstract(English):

A positive electrode precursor includes: a positive electrode active material containing a carbon material; and an alkali metal compound. The positive electrode precursor is characterized in that 5 <=A <= 35 when A (g/m<2>) is the weight of the alkali metal compound in a positive electrode active material layer per one side of the positive electrode precursor; 10 <= B <= 100 when the B (g/m<2>) is the weight of the positive electrode active material in the positive electrode active material layer, and moreover, 0.20 <= A/B <= 1.00; and when C (m<2>/cm<2>) is the specific surface area per unitarea as measured by the BET method per one side of the positive electrode precursor, 1 <= C <= 20.
