Battery structure

Li/MnO2 electrochemical system can be made according to different design and organization, to adapt to the different USES for the various requirements of miniaturization, light-duty mobile power supply. It can have a variety of structures, including COINS, carbon type, winding type and square battery.

Coin battery

Lithium manganese dioxide tablet on the disc anode, middle separated with non woven polypropylene membrane, membrane contamination through the electrolyte. Battery USES the edge compression seal. Battery shell is used as the positive terminal and the lid is used as the negative terminal. This coin cell battery maintains life is 3 years.

Discharge of the battery

The cathode reaction: Li, Li + + e -

The positive reaction: Mn + 4 o2 + Li + + e - - > Mn + 3 o2 (Li +)

Total discharge reaction: Mn + 4 o2 + Li - Mn + 3 o2 (Li +)

Lithium - manganese dioxide battery open circuit voltage is about 3 v, stable discharge voltage is an important characteristic of it.
