Proprietary, multicomponent hydrogen storage alloys using the principles of atomic engineering form the heart of Ovonic Nickel-Metal Hydride (Ni/MH) battery technology. This battery system, in development for 10 years, has been licensed to several manufacturers both for consumer cells and electric vehicle batteries. These cells have achieved a specific energy of over 80 Wh/kg, a peak power in excess of 200 W/kg, and over 1000 cycles at 100% depth of discharge. They also have an intrinsic ability to withstand overcharge and overdischarge abuse. Ovonic Ni/MH batteries are environmentally friendly and can be recycled. Performance data will be presented showing the successful scale-up of this technology for electric vehicle applications.
