| titleOfInvention | Positive electrode active material for lithium ion battery, positive electrode for lithium ion battery, and lithium ion battery |
| abstract | Provided is a positive electrode active material for lithium ion battery, with which it is possible to provide a lithium ion battery with outstanding safety. The positive electrode active material for lithium ion battery has a layered structure represented by the composition formula: Lix(NiyM1-y)Oz (in the formula, M is Mn and Co, x falls within the range of 0.9 to 1.2, y falls within the range of 0.7 to 0.75, and z falls within the range of 1.8 to 2.4). After a lithium ion battery obtained using a positive electrode mixture prepared using 91wt% positive electrode active material, 4.2wt% binder and 4.8% conductive material is charged until the voltage reaches 4.3V, the difference Δ T = T1 - T2 (where T2 < T1) described below satisfies Δ T ≥ 10 ( DEG C). T1 is a first exothermic peak temperature ( DEG C) obtained by differential scanning calorimetry (DSC) at a rate of increase in temperature of 5 DEG C/minute of 1.0mg of positive electrode mixture together with an electrolyte obtained by dissolving 1M-LiPF6 in a mixed solvent of ethylene carbonate (EC) - dimethyl carbonate (DMC) (volume ratio 1:1), and T2 is a temperature ( DEG C) at half the first exothermic peak intensity. |
