摘要 研究了以海藻酸钠为粘结剂制备锂离子电池的加工特性、倍率放电特性及循环特性;分析了海藻酸钠的机械特性。海藻酸钠薄膜具有较高的弹性模量,较羧甲基纤维素钠和丁苯橡胶复合粘结剂体系提升100%,制备的极片粘结力较羧甲基纤维素钠和丁苯橡胶复合体系提升30%。海藻酸钠制备的锂离子电池化成后,阻抗仅为常规羧甲基纤维素钠和丁苯橡胶复合粘结剂体系锂离子电池的一半,在2 C放电（3.0~4.2 V）的容量提升10%。 The process characteristics,rate discharge capability and cycle performance of Li-ion battery prepared by sodium alginate binder were studied. Mechanical properties of sodium alginate were tested. Elastic modulus of sodium alginate improved 100%compared to sodium carboxymethyl cellulose（CMC） ＋ styrene-butadiene rubber（SBR） system,peel strength of electrode with sodium alginate was improved 30% compared to CMC ＋ SBR system. The electrochemical test showed 2 C rate improved 10%because of lower impedance for cell with sodium alginate.
