2)The Principle of Product

    Alkaline zinc-manganese reserve battery is a new type of battery which uses zinc as its cathode, manganese dioxide as its anode and alkaline solution as electrolyte. The active material and electrolyte of this kind of battery are separated from each other, so that pole pieces of the battery are sealed in dry-charged state. In case of use, the battery is activated and is able to discharge when electrolyte is added into it. Alkaline zinc-manganese reserve battery has no electric output and self-discharge during the storage, so that it can provide enough energy when it is activated after a long time of storage.

3)Advantages

a.able to be activated quickly;
b.able to output in large power;
c.able to work continuously for a long time;
d.good chemical stability during long-time storage;
e.wide range of working temperature, suitable in different surroundings;
f.environment-friendly, pollution-free.

 

4)Application

     Range of application: fire fighting, emergency communication, intelligent building, frontier sentry, ships, field working, civil defence, and other emergency power.

    Within the storage period, the battery can be activated at any time and supply electricity for lighting, communication, ventilation, switching, auto door and other electrical devices in 2 minutes.

2)The Principle of Product

    Alkaline zinc-manganese secondary battery is a new kind of battery which is based on and developed from alkaline primary battery such as Nanfu, GP. It can supply strong power as alkaline primary battery, and can also be recharged as regular storage battery. So this product’s energy-saving characteristic fully coincides with the nation’s policy of constructing environment-friendly and resource-saving society.

    In cathode alkaline zinc-manganese secondary battery uses metal zinc as its active material, copper as its current collector; in anode, the active material is manganese dioxide, and current collector is stainless steel. The electrolyte is a solution including KOH. The separator is a composite-material membrane.

    Operational Principal of Battery:
    The chemical formula of the battery:

                  (-)Zn|KOH|MnO2(+) 

Chemical reaction of the battery: 

Cathode:
Zn + 2OH- - 2e-  ZnO + H2O

Anode:
2MnO2 + 2H2O + 2e-  2MnOOH + 2OH-

The overall reaction:
Zn + 2MnO2 + H2O  2MnOOH + ZnO

 

3)Advantages

 

a. Long cycle life, good resistance to overcharge and overdischarge, high short-circuit current.

b. Maintains excellent features of alkaline battery, such as large capacity, low self-discharge rate.

c. Lower cost than other batteries of the same type; suitable for large-scale production.

d. Without poisonous matters like mercury, cadmium, or lead; safe and pollution-free.

 

 

4)Application

    Alkaline zinc-manganese secondary battery can take the place of nickel-cadmium battery and NI-MH battery, and be applied in LED lights, solar energy storage, wind power storage, electrical tools, military equipments, wireless electrical products and other backup batteries. It is also hopeful to be the power battery of some electrical vehicle.
