Reasons why lithium manganese batteries cannot be charged

1. Charging characteristics of lithium-manganese battery: If the primary lithium battery is charged with an external charger, the reverse reaction of the discharge reaction will occur inside the battery, which will decompose the sound B compound MnOOLi, regenerate Li and Mn02, and the battery voltage will also rise.

2. Dangers of charging lithium manganese batteries:

1) Low-boiling organic solvents are used in the production of lithium-manganese batteries, among which the organic solvent of ethylene glycol dimethyl ether has a low lightning point temperature. Glycol dimethyl ether is volatilized from the battery, and if it encounters electric sparks or smoking sparks, it may cause burning hazards.

2) During the charging process of the lithium-manganese battery, the reaction inside the battery will generate Li, which is an irregular crystal with a shape that resembles a branch and is called a dendrite. If the dendrite pierces the separator during the growth process, causing a short circuit inside the battery, accidents such as combustion and explosion may occur.
