Magnesium Battery

Magnesium battery

TM-3 LED Lantern

The following three kinds of Magnesium battery are under developing.

 *Carbon Type

 *Carbonate Type (Coating and Cylindrical shape)

 *Alloy Type

Hybridizing of a Magnesium battery with a Li-ion battery is indispensable because Magnesium battery has characteristics of long time discharge with small current therefore can not respond to Rush Current which requires momentarily big current.
