Electrovaya has introduced MN-HP series cells that use SuperPolymer cell and battery technology. The energy density of MN-eHP cells, which are the energy version of the SuperPolymer technology, is greater than 200 Wh/kg. This is among the highest energy densities that a commercially available Lithium ion cell with a prismatic design can possess.
Electrode materials that are commercially viable, such as lithium metal mixed oxide cathodes and graphite anodes, are used in the MN-HP series cells. These electrode types contribute towards enhanced safety and high cycle life. These MN-HP series cells manufactured by Electrovaya are known for their high energy density. In comparison to the phosphate cells, the MN-HP cells have an energy density that is higher by 50%-70%. They also exceed the energy density of ubiquitous lead acid batteries by 600% and that of lithium titanate cells by 120%.
Electrovaya’s MN-HP series cells are produced by a non-toxic process developed by the company. Poisonous n-methyl pyrrolidone (NMP) is a compound used by manufacturers in commercial lithium ion batteries. This toxic NMP cannot be used in the supply chain for Alternate Energy Storage programs or Green electric vehicles. Moreover, the toxic NMP has been found to cause birth defects in humans.
The advantage of using high energy density cells is that lesser number of materials is required to process them, which in turn reduces the production cost. Flammable electrolytes are present in fewer amounts in these cells, and this contributes to the safety factor. Electrovaya's MN-HP series cells are packed in a flat pouch made of polymer, and are available with capacities ranging from 30Ah to 40Ah (110Wh - 150Wh).
