| BATTERY KNOWLEDGE |

Welcome to our battery knowledge page. Here you will find some quick notes on batteries and battery assemblies. This page is designed to help our customers become more familiar with the general principles of battery assemblies. If you have questions or would like us to add more information relevant to your needs, please contact us.

Basic Assembly Process:

 

Some Typical Equations and Chemical Reactions:

Ohm's Law: E=I*R (E=Volts, I=Amps, R=ohms)
Power: P=E*I or P=(I*I)*R (P=Watts)
Amp-Hours: expected life (hours)*Average amps=Amp-Hours

Current (Amp)=Volts/Resistance
Resistance (ohms)=Voltage/Current
Voltage=Current*Resistance

NiCD:

At the positive
NiOOH + H20 + e-
reaction arrows Ni(OH)2 + OH-

At the negative
Cd + 2OH reaction arrows Cd(OH)2 + 2e-

Overall
2NiOOH + Cd + 2H2O reaction arrows 2Ni(OH)2 + Cd(OH)2

NiMH:

At the positive
NiOOH + H20 + e-
reaction arrows Ni(OH)2 + OH-

At the negative
MH + OH- reaction arrows M + H2O + e-

Overall
NiOOH + MH reaction arrows Ni(OH)2 + M
(M: Hydrogen absorbing allowy, MH: Metal Hydride)

Lithium Primary :

At the negative
(Li-Al )
reaction arrows Al + Li+ + e-

At the positive
MnO2 + Li+ + e- reaction arrows MnO2 (Li+)

Overall
MnO2 + (Li-Al) reaction arrows MnO2(Li+) + Al
(Li-Al : lithium alluminum alloy)
