Lithium Ion
Electro Energy is the only U.S. based, high-volume manufacturer of cylindrical rechargeable Lithium-ion cells. The company’s Gainesville facility can produce over 30 million 18650 cells a year.
Electro Energy is also developing a Lithium-ion Polymer (LIP) design that successfully eliminates many of the problems associated with standard prismatic cells, including:
- 20% increase in energy over state of the art prismatic cells
- 20% increase in power density over state-of-the-art prismatic cells
- 20% increase in energy over batteries made up of state-of-the-art prismatic cells
- 20% increase in power density over batteries made up of state-of-the-art prismatic cells
- Reduce volume of existing Lithium-ion batteries by 15% - 30%
- Fewer parts (no external cell terminals or electrode current collectors)
- Less weight and volume
- Higher power/longer life
- Greater resistance to cell leakage
- Significant reduction in manufacturing cost
- Highly scalable
- Environmentally friendly
The cell is modeled after Electro Energy’s proven bipolar designs using NiMH chemistry. The 30v/9 Ah wafer Cell Lithium-ion prototype battery module has the following characteristics:
- 9.7 Ah, 285 Wh battery
- 210 Wh/kg at the cell level, 185 Wh/kg battery
- Capable of 1C continuous rates and 4C pulses
- Very good cycle life (up to 500 full DOD cycles)
- Safer than standard prismatic cells
- Very good low temperature performance
