Patent ID: 7659032

Claim:
A method for preparing d-MoS 2 (FeS 2 , ZnS) as a cathode active material, comprising: obtaining disordered-MoS 2 (d-MoS 2 ) by sintering powdered MoS 2 ; obtaining FeS 2 after mixing by ball-milling FeS and S and reacting FeS and S under a temperature program; obtaining a mixture of d-MoS 2 and FeS 2 after mixing by ball-milling the d-MoS 2 and FeS 2 ; and adding ZnS to the mixture of d-MoS 2 and FeS 2 , and ball-milling the ZnS and the mixture of d-MoS 2 and FeS 2 .
