ACTIVE MATERIAL FOR CATHODE AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a cathode active material and a manufacturing method thereof capable of enhancing electrical conductivity by including: a step (S10) for preparing an intermediate phase aggregating agent (20) which is formed with lithium titanium oxide particles (11); a step (S20) for preparing resorcinol-formaldehyde (RF) sol (21a); a step (S30) for manufacturing a mixed aggregating agent (30) by mixing the RF sol (21a) with the intermediate phase aggregating agent (20) which is formed with lithium titanium oxide intermediate phase particles (11) if the intermediate phase aggregating agent (20) which is formed with lithium titanium oxide intermediate particles (11) and the RD sol (21a) are prepared; a step (S40) for substituting acetone for solvent by soaking the mixed aggregating agent (30) in the acetone if the mixed aggregating agent (30) is manufactured; and a step (S50) for manufacturing a complex aggregating agent (40) which is formed with lithium titanium oxide final phase particles (12) and carbon aerogel (21) by thermally treating the mixed aggregating agent (30) which is substituted with the acetone. [Reference numerals] (S10) Lithium titanium oxide intermediate phase particle; (S20) RF sol; (S30) Mixture; (S40) Substitution; (S50) Heat treatment
