When there are more nickel atom doped in spinel ( the mole ratio of mn and ni was 1 . 4 : 0 . 6 ) , the discharging platform jumped to 4 . 5v from original 3 . 8v . the materials showed to suit for positive materials in 5v lithium ion batteries
在纯尖晶石中掺入的镍量较大时(锂锰的摩尔比为1 . 4 : 0 . 6 ) ，样品的放电区间移到4 . 5v左右，得到适合做5v锂离子电池的正极材料。
