We think increase of the internal resistance of battery is the main problem to the recycle life deteriorating at high rate , besides the influence of the materials . decomposition occurred on positive and negative electrode at high rate current and the interspaces increased . the restrains of swelling and the increase of an oxygen overvoltage can improve the performance of recycle life 對于電池性能衰減的原因,認(rèn)為除了所使用的材料是影響電池性能的重要因素之外,在溫度和大電流作用下,電池的正負(fù)極材料發(fā)生裂解,極片內(nèi)空隙增大,電池內(nèi)阻性能惡化是引起電池高倍率循環(huán)性能惡化的關(guān)鍵;通過抑制正極析氧和膨脹,并降低負(fù)極合金材料的粉化過程,將有望緩解電池內(nèi)阻特性的惡化,從而提高電池高倍率充放電循環(huán)性能。
