锂二次电池
摘要：
一种锂二次电池包括：含有正极活性材料的正极；负极；以及非水电解液。所述正极活性材料是非晶，且由LixA[PaM1-a]yOz表示，其中，在该式中，A为Mn或Ni；M为具有比P低的电负度的玻璃形成元素；且x、y、a和z分别满足1＜x≤2.5，0＜y≤3，0≤a＜1以及z＝(x+(A的价数)+(P的价数)×a×y+(M的价数)×(1-a)×y)/2。
摘要（英）：

A lithium secondary battery includes: a positive electrode that contains a positive electrode active material; a negative electrode; and a nonaqueous electrolyte. The positive electrode active material is amorphous and is expressed by LixA[PaM1-a]yOz where, in the formula, A is Mn or Ni; M is a glass former element having an electronegativity lower than P; and x, y, a and z respectively satisfy 1 < x <= 2.5, 0 < y <= 3, O< = a < 1 and z = (x + (valence of A) + (valence of P)*a*y + (valence of M)*(1-a)*y)/2.
