The
reaction formula of Ni-Cd batteries:
2Ni(OH)2+Cd(OH)2 2NiOOH+Cd+2H
2O
The reaction
formula of Ni-MH batteries:
Ni(OH)2+MNiOOH+MH (M:hydrogen-absorbing alloy)
Nickel is used
as the positive electrode and cadmium as the negative electrode in nickel
cadmium batteries, while the negative electrode is hydrogen absorbing alloy
in nickel metal hydride batteries. The potassium hydroxide used
as the electrolyte and the foam electrodes, enable high
energy density as well as excellent charge/discharge and
thermal characteristics in TEIG
batteries.
TEIG
batteries have highly designed safe structure. The rigid stainless
steel case has a high endurance to internal pressure and a resealable gas release
vent is provided to guard against increased internal gas pressure generated be
improper use of batteries. The following diagram shows the interior
of a TEIG
battery . |
