Composite active material for lithium secondary batteries and method for producing same |
| abstract |
Provided is a production method for a composite active material for lithium secondary batteries which enables production of an electrode material in which volume expansion is suppressed even after repeated charging and discharging, and enables production of a lithium secondary battery exhibiting excellent cycle characteristics. A composite active material for lithium secondary batteries is produced using a mixing step of mixing graphite having a specific surface area of not less than 30 m 2 /g, silicon monoxide, and a carbon precursor to obtain a mixture; a conglobation step of performing conglobation treatment on the mixture and obtaining a spherical mixture; and a heating step of heat-treating the spherical mixture and producing a substantially spherical composite active material for lithium secondary batteries. |
