"textContent": "The present application discloses a secondary battery, an apparatus comprising the secondary battery, a process for the preparation of the secondary battery, and a binder composition. The secondary battery comprises a binder for bonding a first substance and a second substance, the binder comprising a polymer obtained by crosslinking a binder composition, wherein the binder composition comprises a cross-linkable polymer matrix and a cross-linking agent, the cross-linkable polymer matrix comprises one or more of monomer units represented by formula (I), and the cross-linking agent comprises a compound represented by formula (II), in which R, R and R are each independently selected from H and straight-chain or branched-chain alkyl groups with 1 to 8 carbon atoms; R is a polar group containing an active hydrogen; R is a reactive group to R; R is selected from H and substituted or unsubstituted hydrocarbon groups with 1 to 8 carbon atoms; and n is an even number greater than or equal to 4, 2≤m≤n. The secondary battery provided by the present application has an effectively improved cycle life.",
