同时，很多设备的电池都是内设固定的，如果没有及时充电，没电后电子设备就不能使用，如果遇到应急或者在户外，电池没电会造成一定程度的不便。如果是一些可更换电池的电电子设备，经常更换电池一方面比较繁琐，另一方面也不利于环保。
发明内容
本发明解决的技术问题是提供一种无限容量超薄锂电池，本发在电量较低时，太阳能光伏板自动给锂电池补电，从而实现永久续航，至少保证10年以上续航。

优选的，在所述极耳和所述太阳能光伏板之间设有电阻和IC芯片。IC芯片一方面可以通过控制电阻，进而控制输出电流和电压的大小，使得输出电压范围更广，应用更广。
优选的，所述极耳包括正极极耳和负极极耳，在所述正极极耳和所述负极极耳均设有处理层。
优选的，所述的极耳处理层为等离子层或电晕层。极耳处理层使得极耳和其他器件之 间的连接更为稳定。
