Iron oxide-based electrode for alkaline battery - contains minor amt. of crosslinked carboxylated styrene!- butadiene! copolymer for improved mechanical properties

摘要

In the Fe oxide-based electrodes the active component contains 1-2.5 wt.% crosslinked carboxylated styrene-butadiene copolymer (I). Prodn. of the electrodes is claimed in which the active component is prepd. as a paste, applied on a metal current collector by calandering or coating, dried, then heated at 120-150 deg.C for several minutes to crosslink the copolymer. Pref. the active component also contains 0.2-2 wt.% PTFE on wt. of active component in initial dry state.
