摘要/Abstract

摘要： 锂离子电池内短路是诱发电池热失控的主要原因，适当的安全性添加剂可以阻止电池热失控的发生。本文通过界面聚合法在聚乙烯蜡表面生成适量的导电聚苯胺，制备了一种具有良好导电性能的PTC材料（PANI-PEW），并对PANI-PEW的微观形貌、电导率以及添加至LiFePO₄正极中的电化学性能进行了对比分析。测试结果表明，PANI-PEW在常温下的电导率为1.08×10^-3 S/m，在90~120℃时，其电阻值急剧增大。在0.5 C和1 C倍率下，PANI-PEW的加入对LiFePO₄电池的阻抗和循环性能影响较小，而经过120℃热处理后的含15%（质量分数） PANI-PEW的极片，其电池的阻抗大幅增加且首次放电比容量只有35.3 mA·h/g，在第12次循环后，放电比容量接近于0。以上结果表明，PANI-PEW是一种性能优异的PTC材料且能在120℃时阻止电池热失控的发生。

Abstract: Short circuit in lithium ion battery is the main cause of thermal runaway, the proper safety additives can prevent the thermal runaway. A positive temperature coeffcient material (PANI-PEW) was prepared by polymering amount of PANI particles on the surface of PEW. The morphology and conductivity of PANI-PEW, the electrochemical performance of LiFePO₄ batteries with PANI-PEW were tested at room temperature and 120℃. The results showed as follow:the conductivity of PANIPEW was 1.08×10^-3 S/m at room temperature and its resistant increased rapidly during 90~120℃. It had little effect on the impedance and cycling performance when PANI-PEW introduced into LiFePO₄ battery at 0.5 C and 1 C. But the impedance of LiFePO₄ battery with 15% PANI-PEW increased rapidly and the frst specifc capacity only was 35.3mA·h/g after the LiFePO₄ electrode with 15% PANI-PEW was treated at 120℃ for 1 min, even after the 12th cycle, the specifc capacity closed to 0. This study indicate that the PANI-PEW is an excellent PTC composite and improved the safety performance of LiFePO₄ battery at 120℃.
