新能源电池是一种使用新能源材料作为主要原料，例如锂电池、燃料电池等

的电池。由于其环保性和高能量转换效率，这些电池已成为新能源产业的重

要组成部分。新能源电池的基本原理在于通过一系列电化学反应将化学能转

换为电能。

新能源电池的结构通常包括阳极、阴极和电解质。阳极是氧化发生的正极，

释放电子。阴极是还原发生的负极，接受电子。电解质作为阴极和阳极之间

的离子传输介质，使电流得以传递。

在锂离子电池中，阳极通常由石墨制成，阴极由氧化钴酸锂制成，电解质通

常是溶解在有机溶剂中的锂盐。当电池充电时，锂离子从阴极释放，并通过

电解质移动到阳极进行储存。在放电过程中，锂离子移回阴极释放能量。
