Cathode active material for secondary battery and manufacturing method thereof |
| abstract |
The present invention relates to a cathode active material for a secondary battery and a manufacturing method thereof. A cathode active material, according to one embodiment of the present invention, comprises silicon-based primary particles, and a particle size distribution of the silicon-based primary particles is D10 ≥ 50 nm and D90 ≤ 150 nm. The cathode active material suppresses or reduces tensile hoop stress generated in lithiated silicon particles during a charging of a battery to thus suppress a crack due to a volume expansion of the silicon particles and/or an irreversible reaction caused by the crack, such that the lifetime and capacity of the battery can be improved. |
