1 APPLICATIONS
The specification applies to the following sealed Ni-CD rechargeable battery made by
SUNRISE.
TYPE:NI-CD APPLICATION： Electric Tools and Electric toys Etc.
2 WORKING THEORY
The negative of Sunrise Nickel-Cadmium cylindrical battery is metal of Cadmium, the
positive is
NiOOH, The electrolyte is NaOH of high purity. The electrochemical process are
represented by
the following reactions:
At the positive electrode：2NiOOH+2H
2
O+2e 2Ni(OH)
2
+2OH
-
At the negative electrode：Cd+2OH
-
-2e Cd(OH)
2
Overall reaction：Cd+2NiOOH+2H
2
O 2Ni(OH)
2
+Cd(OH)

During discharge, Cadmium of negative is oxidized to Cd(OH)
2,
The free electrons
flow into the positive through the external circuit, NiOOH of positive receive the
electrons and be deoxidized to Ni(OH)
2.
Charge process is just the opposition of
discharge.
