Lithium Iron Phosphate – LiFePO4
This is the current lithium battery industry standard. LiFePO4 is a naturally occuring mineral. LiFePO4 batteries are the safest deep cycle Lithium battery because they will not overheat and will not ignite even if they’re punctured. The cathode is actually made of LiFePO4 coated with Carbon nanotubes and as such poses no negative health hazards or environmental hazards. LiFePO4 chemistry provides a number of advantages over Lithium-Ion chemistry:
- Up to 5 times the number of cycles
- 12.8 Volts (Lithium Ion batteries are 11.1 Volts)
- Greater operating temperature range
- Safer
- Voltage remains constant during most of discharge
