Zinc-air battery

Zinc-air battery, activated carbon adsorption of oxygen in the air or pure oxygen as the positive electrode active material, zinc anode, chloride and caustic soda solution as the electrolyte a galvanic cell. Also known as zinc-oxide battery.

Zinc-air batteries the charging process is very slow, in order to solve this problem, usually negative electrode of zinc-air battery and zinc or zinc capsules, after failure is oxidized to zinc oxide, generally by direct replacement of zinc and zinc particles and method of electrolyte, the zinc-air battery is fully updated.

Lithium-air battery

Large capacity lithium-air battery is not a new concept, has not become widespread because it is fatally flawed.

At present, the lithium ion battery is the next-generation plug-in hybrid cars and the ideal choice for electric vehicles, but its potential is limited. Theoretical energy density than lithium ion batteries lithium metal-air batteries cause for concern. Its new greatly improve the energy density of batteries. Because on the positive use of oxygen in the air as active substances, positive volume density is theoretically unlimited, to increase capacity. In addition, if the cathode using lithium, theoretical capacity than lithium-ion rechargeable battery will increase one digit.

But lithium-air battery has been popular because it is fatally flawed, that accumulation of solid reaction of lithium oxide in the cathode, the electrolyte come into contact with air is blocked, resulting in a discharge stopped.

Aluminum-air battery

Aluminum-air batteries, as the name suggests is based on aluminum with air as a new battery to battery materials. It is a pollution-free, long-lasting, stable and reliable power supply, is a very environmentally friendly batteries. Cell structure and the use of raw materials according to different practical environment and requirements change, possesses great adaptability, can be used in both the land can also be used in the deep sea, both batteries and signals more attentions are being paid with long life battery, is a very powerful batteries, has a very broad application prospects.
