电池原理：锌空电池全称是锌空气电池或锌氧电池，金属锌作电池的负极，空气中的氧气作正极，其原理是锌和氧在电池内发生电化学反应，将化学能转化成电能。Battery principle: The full name of zinc-air battery is zinc-air battery or zinc-oxygen battery. The metal zinc is used as the negative electrode of the battery, and the oxygen in the air is used as the positive electrode. The principle is that zinc and oxygen undergo an electrochemical reaction in the battery to convert chemical energy into electrical energy. .

正极：1/2O2+H2O+2e→2OH¯Positive electrode: 1/2O 2 +H 2 O+2e→2OH¯

负极：Zn→Zn2++2eNegative electrode: Zn→Zn2++2e

总反应： 1/2O2+ Zn = ZnOTotal reaction: 1/2O 2 + Zn = ZnO

利用空气中的氧气和电池中的金属锌在催化剂的作用下进行反应而产生直流电。而生成物氧化锌经过电解还原（即储能）又生成金属锌，从而再次投入反应，再放电、再还原（再储能），如此循环往复。Direct current is generated by using oxygen in the air and metal zinc in the battery to react under the action of a catalyst. The product zinc oxide undergoes electrolytic reduction (that is, energy storage) and then generates metal zinc, which is put into the reaction again, then discharged, and then reduced (restored energy), and so on.

锌空电池既是一种燃料电池，又是一种高效储能工具；既可以作为原电池直接使用，又可作为其它电池的充电电源。Zinc-air battery is not only a fuel cell, but also a high-efficiency energy storage tool; it can be used directly as a primary battery or as a charging power source for other batteries.

以上所述的实施例仅仅是对本发明的优选实施方式进行描述，并非对本发明的范围进行限定，在不脱离本发明设计精神的前提下，本领域普通技术人员对本发明的技术方案作出的各种变形和改进，均应落入本发明权利要求书确定的保护范围内。The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the scope of the present invention. Variations and improvements should fall within the scope of protection defined by the claims of the present invention.
