Comparison of battery chemistries
There are quite a few battery parameters & based on the different applications a battery is used for, certain parameters are more important than other parameters.
Lead acid battery - lithium ion - Comparison of battery chemistries
| Parameter | Lead Acid Battery | Lithium Ion Battery |
Nickel Metal (NiMH) Hydride Battery |
Nickel Cadmium Battery (Ni Cad) |
|---|---|---|---|---|
| Cell Voltage | 2.1 V | 3.2 - 4.7 V | 1.2 V | 1.2 V |
|
Energy Density Wh/Kg |
25-45 | 120-180 | 60-120 | 45-80 |
| Life Cycles | 200 - 500 | 500 - 1000 | 300 - 500 | 1500 |
| Operating Temperatures | -20 ᴼC to 60 ᴼC | -40ᴼC to 70ᴼC | -20ᴼC to 60ᴼC | -40ᴼC to 60ᴼC |
| High Current Discharge | Good | Excellent | Good | Poor |
| Capacity at Different Rates | Ah** Capacity decreases with increasing discharge current | Ah Capacity is almost constant at all discharge rates | Ah Capacity is almost constant at all discharge rates | Ah Capacity decreases with increasing discharge current |
