Hybrid Technologies Inc. Develops New "Superlattice Structure" Lithium Battery

February 28, 2008 by Jeff Shepard

Hybrid Technologies, Inc. (HTI) announced a successful move toward development of a new cathode material which will be incorporated to a Lithium Ion polymer battery that significantly increases operating voltage range and energy density.

The company’s new battery consists of a new cathode material with a "Superlattice Structure" allowing electric vehicles to be driven over 200 miles compared to the current 120 to 140 mile range and operates at a wide voltage range of 4.3 to 2V. The pure material was produced in-house and has been synthesized at an industrial scale.

HTI has started in house production of all "Superlattice Structure" in a higher density and optimizing the process parameters suitable for large batteries which will be used not only in electric vehicles but also in the field of "Uninterrupted Power Supply (UPS)."

At present HTI is using a lithium ion polymer battery that uses manganese based cathode materials with 100Ah capacity per cell. The capacity of the material is around 120 Ah/kg. To overcome this limitation, the battery division of HTI is conducting research on a series of cathode materials with superlattice structure. The objectives of this research are to model different cathode structures and optimize process parameters to obtain a single phase and pure material in industrial scale.

HTI’s R&D division has successfully synthesized a cathode material with a superlattice oxide structure and the material is based on manganese, cobalt, nickel and titanium. In the first batch 100kg of phase pure material has been produced.
