September 9, 2008: Superlattice Power Inc., a global developer of lithium-powered batteries, announced that its North Carolina production facility has successfully produced 200kg of a new high-purity nanocathode material. The high purity cathode material is ready to be used in a battery manufacturing facility for the use in electric vehicles. The battery, produced using new cathode material, will have wide voltage range from 4.2-2V per unit cell.
Superlattice Power says it is now devoted for the development and large-scale production of cobalt-free cathode material with superlattice structure for a high-voltage application using a new electrolyte capable to withstand >5V voltages. Research was performed with a Fortune 500 electronics and telecommunication company to develop prototype cells with high energy density.
