5.Lead Carbon Working Principle
Fig.1-2 Lead carbon battery working principle sketch map
It forms a new active center in negative electrode by adding active carbon, that can
reduce lead deposition overpotential, the lead sulfate will be translated into lead more
easily. Growing up of lead sulfate can be suppressed efficiently through this
technology.

The chemical reaction taking place in lead carbon battery is as follows:
positive electrode:
negative electrode:
Because of the reaction is based on double layer capacitance which caused from
carbon electrode/electrolyte interface, thereby the lead carbon battery has part
characteristic of super capacitors. Thus the lead carbon battery can possess large
current and long cycle life performances.
REXC battery adopts a design of barren-liquor and utilizes AGM (micro porous glass
fiber) separator. Thus there is a path existing between the positive and the negative.
