PROCESS FOR SYTHESIZING SPINEL-COATED SINGLE-CRYSTAL CATHODE ACTIVE MATERIALS

A method for manufacturing cathode active material includes providing a polycrystalline transition metal precursor; providing a lithium salt composition including a first lithium salt and a second lithium salt having a eutectic melting temperature; creating a first mixture including the polycrystalline transition metal precursor and the lithium salt composition; mixing the first mixture in a mixer to generate inter-frictional force to heat the lithium salt composition above the eutectic melting temperature and to generate a second mixture; and sintering the second mixture to form a spinel-coated single-crystal cathode active material.
