| titleOfInvention | Positive electrode active material for lithium-ion batteries, positive electrode for lithium-ion battery, and lithium-ion battery |
| abstract | Disclosed is a positive electrode active material for lithium-ion batteries which provides lithium-ion batteries with excellent safety. The positive electrode active material for lithium-ion batteries 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 0.75 ± 0.025, 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 ? T = T1 - T2 described below satisfies ?T = 15 (°C). T1 is a first exothermic peak temperature (°C) obtained by differential scanning calorimetry (DSC) at a rate of increase in temperature of 5°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 second exothermic peak temperature (°C) measured under the same conditions. |
