摘要
A method for producing a secondary battery electrode, according to the present invention, comprises: a slicing step for producing an active material film by slicing an active material bulk; and a binding step for combining a current collector and the active material film. A method for producing a secondary battery electrode according to the present invention produces an active material film by slicing an active material bulk, which is a free-standing molded body or pellet, thus allowing binder-free active material film to be produced, and as no actual restrictions exist for the thickness of the active material film, thick active material film can be produced, and thus electrodes having high-loading and high composite density can be produced.

The electrolyte may be any common non-aqueous electrolyte which smoothly conducts ions involved in charge and discharge of a battery, in the common lithium secondary battery. As an example, the non-aqueous electrolyte may include a non-aqueous solvent and a lithium salt. As a non-limiting example, the lithium salt contained in the electrolyte may be a salt providing lithium cations and one or more anions selected from the group comprising NO3, N(CN)2?, BF4?, ClO4?, PF6?, (CF3)2PF4?, (CF3)3PF3?, (CF3)4PF2?, (CF3)5PF?, (CF3)6P?, CF3SO3?, CF3CF2SO3?, (CF3SO2)2N?, (FSO2)2N?, CF3CF2(CF3)2CO?, (CF3SO2)2CH?, (SF5)3C?, (CF3SO2)3C?, CF3(CF2)7SO3?, CF3CO2?, CH3CO2?, SCN?, and (CF3CF2SO2)2N?.
