Superior Lithium Ion Phosphate Chemistry including NanoPhopsphate® for power & LiFePO4 for energy
Lithium Werks Power Cells
Lithium Werks power cells are based on technology originally developed at M.I.T. for superior power performance called NanoPhosphate®. The NanoPhosphate technology is structurally different than other iron phosphates, allowing much higher rate capability and resulting in higher power, increased safety, and better life.
Valence’s Battery Module Chemistry
Valence’s Lithium Iron Phosphate (LiFePO4) modules have considerably greater energy density making them particularly suitable for numerous applications. LiFePO4 is considered safer, less toxic, and more energy efficient with significantly longer cycle life than mixed oxide chemistries. Other benefits include internal cell balancing, less maintenance, low weight, and high energy density.

Commonly used in starter batteries for internal combustion engine (ICE) vehicles Lead Acid is normally a low-cost secondary battery, composed of a Lead-dioxide cathode, a sponge metallic lead anode and a sulphuric acid solution electrolyte. The heavy metal element makes lead acid batteries toxic and improper disposal can be hazardous to the environment.
Disadvantages of Lead Acid batteries include
- Failure between several hundred and 2,000 cycles
- Comparatively low energy density
- Long charge time
- Careful maintenance requirements
- Sudden failure
- High rate of self-discharge at high temperature.
- Cadmium is highly toxic
- Use in batteries is controlled
- Environmental recycling issues
- Memory effect is one of the biggest disadvantages to using NiCd
- Higher cost
- Relatively low specific energy compared with newer systems
- Memory effect / requires periodic full discharges
- Environmentally unfriendly; cadmium is a toxic metal and cannot be disposed of in landfills
- Poor charge retention / needs recharging after storage
- When not in use Sodium (Na-NiCl2) batteries typically require to be left on charge, in order to be available for use when needed.
- If shut down,the reheating process lasts 24 hours, and then a normal charge process of 6-8 hours is required for a full charge.
- Inefficiency due to energy consumption when not in use.
