Expanded graphite particularity application
1 Application of ordinary zinc-manganese batteries (batteries) in
Ordinary zinc-manganese batteries batteries currently used in most of the present acetylene black Century Germany, the United States used its production process more stringent requirements, more expensive,
And electrical conductivity less than ideal. The use of high-purity expanded graphite instead of acetylene black as an electrode, the open circuit voltage, short circuit current, load voltage is higher than the production of batteries acetylene black,
But also to improve the conditions of production, reducing production costs.
2 Application of mercury-free high-energy batteries
Expanded graphite can be used in mercury-free high-energy battery - alkaline high-energy silver oxide battery, this battery cathode material is Ago or Ag O, but whether it is or Ago
Ag20 are weakly conductive material, it must be added the right amount of conductive media is available to make a cathode having a suitable conductive properties when it is used as a cathode. Currently widely used
Is 5% to 15% of amorphous graphite as a conductive medium in a silver oxide cathode material. If you use expanded graphite, compared with the earthy graphite, with less conductive
Pulse characteristics and strong and made of a battery has a higher voltage can be increased by 15% to 30%, the fundamental reason is that the layered structure of expanded graphite containing silver oxide cathode
Inline key to make contact with each other throughout the cathode and graphite particles, and silver oxide cathode containing no earthy graphite in this layered structure.
