| titleOfInvention | Positive electrode active material for lithium ion battery, positive electrode for lithium ion battery, and lithium ion battery |
| abstract | Disclosed is a positive electrode active material for lithium ion battery, which can be used to provide lithium ion batteries with an exceptionally high degree of safety. The positive electrode active material has a layered structure, and is 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 0.8 +- 0.025, and z falls within the range of 1.8 to 2.4). For a first lithium ion battery obtained using positive electrode mixture prepared with 91wt% positive electrode active material, 4.2wt% binder and 4.8wt% conductive material, charged until the voltage reaches 4.4V, and a second lithium-ion battery charged until the voltage reaches 4.1V, the difference Δ T = T41 - T44 described below satisfies Δ T = 15 ( DEG C). T44 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) for the first lithium-ion battery, and T44 is the same value for the second lithium-ion battery. |
