摘　　要：ＳＢＳ粘合的金属氢化物电极的性能，尤其是循环性能优于ＰＴＦＥ、ＨＰＭＣ等粘合的ＭＨ电极．不同溶剂对ＳＢＳ粘合电极的性能影响较大，经丁酮化学处理后，以松节油为粘合剂溶剂的ＳＢＳ电极容量最大，内阻最小，大电流放电能力最强；压片温度对电极性能影响也较大。Styrene butadine styrene elastomer(SBS) has been found to be a better binder than PTFE and HPMC in preparation of metal hydride electrode. On binding with SBS, three solvents have been tested: toluene, turpentine oil and butyl acetate, among them the turpentine oil appeared most favorable. In the last case the electrode had the highest dischargeability in high current, discharge capacity and the least inner resistence. The optimum shaping temperature for electrode preparation was 80 ℃.
