Abstract

本发明涉及电池领域尤其涉及一种二次电池及其制备方法。该二次电池包括电池负极、电池正极以及固态电解质层或凝胶态电解质层，其中，电池负极包括负极集流体，不包含负极活性材料；电池正极包括正极集流体和正极活性材料层，正极活性材料为自由可逆脱嵌锂离子、钠离子或镁离子的正极活性材料。由于采用固态电解质层或凝胶态电解质层替代了常用的液态有机电解液，不易腐蚀电极材料，提高了电池运行时的稳定性，增加了电池的使用寿命；由于采用固态电解质层或凝胶态电解质层从而不需要隔膜，缩小了电池体积，增大了电池的能量密度；同时本发明提供的二次电池取消负极活性物质，不仅降低电池生产的成本，同时还能有效的提高电池的电池容量及能量密度，并且具有良好的充放电循环性能。
