Knowledge
There are three types of Li-Ion cells on current market based on chemistry of cathode materials. Please see the table below to see advantage and disadvantage of each type cell. Among of them, LiCoO2series Li-Ion cell has the highest energy density and is most popular cell using in the market. LiFePO4 and LiMnNiO4 cell still are in developing
| Chemistry | Voltage | Energy Density | Working Temp. | Cycle Life | Safety | Environmental | Cost based on cycle life x wh of SLA |
| LiFePO4 | 3.2V | >120 wh/kg | -0-60 °C | >2000 | Safe | Good | 0.15-0.25 lower than SLA |
| Lead acid | 2.0V | > 35wh/kg | -20 - 40°C | >200 | Safe | Not good | 1 |
| NiCd | 1.2V | > 40wh/kg | -20 - 50 °C | >1000 | Safe | Bad | 0.7 |
| NiMH | 1.2V | >80 wh/kg | -20 - 50 °C | >500 | Safe | Good | 1.2-1.4 |
| LiMnxNiyCozO2 | 3.7V | >160 wh/kg | -20 - 40 °C | >500 | Unsafe without PCB or PCM, better than LiCo | OK | 1.5-2.0 |
| LiCoO2 | 3.7V | >200 wh/kg | -20 - 60 °C | > 500 | UnSafe without PCB or PCM | OK | 1.5-2.0 |
