New materials and processing techniques are needed to provide a high power storage device for usage in a hybrid electric vehicle (HEV). AVEKA has developed a unique nanophase V205 material that is capable of storing and delivering large amounts of energy in a short period of time. AVEKA will utilize its proprietary coating technology to form a nanocomposite laminate from this material which can be utilized as a high energy density battery cathode. This prototype battery will not need external cooling and will be able to withstand wide extremes in operating environments. Rechargeable batteries, such as will be developed in this work, have several uses in commercial electronics and in electric vehicles.

Hybrid electric vehicles, in contrast to electric vehicles, require a storage battery that is capable of fast charge/discharge rates in addition to a high storage capacity. AVEKA, Inc. has formulated an amorphous form of vanadium pentoxide that surpasses the performance of its crystalline form at the high charge/discharge rates. The capacity and rate capability of this material also have not yet been fully determined. AVEKA plans to refine the manufacture and performance of this material in phase II of this program and incorporate it into rudimentary cells for evaluation and performance testing initially, and finally utilize these materials in battery packs for full scale testing and production.The military and civilian sectors of the government have needs for a small high rate, high capacity battery in several applications. This battery and the chemistry that it is based have the potential to control several markets for these battery products with very little competitive
