Description

The long-term objective of research has been to perform the enabling materials research necessary for the development of a battery oriented to the consumer market with special requirements in terms of safety, cycling life, and high specific energy and power. We have discovered novel processing of V{sub 2}O{sub 5} gels that leads to aerogel (ARG) and xerogel (XRG) films with specific energy and Li insertion capacity that are much higher than for other amorphous or crystalline forms of V{sub 2}O{sub 5}. We have also found that the new materials will host Mg{sup +2} and other cations which should be the ... continued below

Description

The long-term objective of research has been to perform the enabling materials research necessary for the development of a battery oriented to the consumer market with special requirements in terms of safety, cycling life, and high specific energy and power. We have discovered novel processing of V{sub 2}O{sub 5} gels that leads to aerogel (ARG) and xerogel (XRG) films with specific energy and Li insertion capacity that are much higher than for other amorphous or crystalline forms of V{sub 2}O{sub 5}. We have also found that the new materials will host Mg{sup +2} and other cations which should be the basis for novel high-energy, high-power consumer battery systems. The investigation has examined (1) low-temperature synthesis of V{sub 2}O{sub 5} aerogel host materials, (2) characterization of insertion of Mg{sup 2+}, Zn{sup 2+}, and Al{sup 3+} into the V{sub 2}O{sub 5} hosts, (3) anode materials for the new systems, and alternate anode materials to replace the intrinsically unsafe lithium metal for lithium batteries, and (4) the feasibility of safer, nonaqueous, high-performance battery designs.
