Electrovaya Launches Next Generation Lithium Ion Superpolymer Cell & Battery Technology: MN-HP Series

September 25, 2012 by Jeff Shepard

Electrovaya Inc. announced the launch of its next generation SuperPolymer cell and battery technology, the "MN-HP Series". The Energy version of this technology, MN-eHP exceeds 200Wh/kg, which the company believes is one of the highest energy densities for a commercial Lithium Ion cell in a large prismatic design.

Electrovaya's MN-HP series cells use commercially proven electrode materials such as graphite anodes and lithium metal mixed oxide cathodes to give excellent cycle life and good safety. Electrovaya's MN-HP cells typically have 50-70% higher energy density than typical phosphate cells, over 120% higher energy density than lithium titanate cells and about 600% higher energy density than the ubiquitous lead acid batteries.

Higher energy density cells require fewer materials for a given energy capacity and therefore can be produced at lower costs. Higher Energy Density cells also contain proportionately lower amounts of flammable electrolytes, which substantially improve safety considerations. Typical MN-HP cells are available in 30Ah to 40Ah format (110 - 150Wh) and housed in a flat polymer pouch.

The cells are produced by Electrovaya's proprietary non-toxic production process which does not use massive quantities of toxic n-methyl pyrrolidone (NMP), unlike most other commercial lithium ion battery manufacturers. Toxic NMP is suspected of causing birth defects and does not obviously complement the supply chain for Green electric vehicles or Alternate Energy Storage programs.
