JOULE
Abstract
(U) The JOULE program will exploit new architectures, reversible electrode structures, materials, and chemistries for the development of rechargeable, high energy density batteries that match or exceed energy density of hydrocarbon fuels (e.g. gasoline, JP8, etc.). This technology will target replacing gasoline in both military and civilian transportation applications. These high energy density batteries will also lighten the payload and extend mission capabilities for the dismounted soldier. The program will significantly increase the stoichiometric limits on reducible charge capacity in reversible batteries by developing non-crystalline positive electrode structural materials with lightweight structural approaches and new chemistries. Three-dimensional structures with very high surface areas for electrodes will increase the power density of these batteries. The program will develop new chemistries for positive electrodes to demonstrate reversibility in the graphite fluorite (a high-voltage, high-capacity material) class of positive electrode materials in reversible batteries for the first time. The energy density will increase over ten-fold current lithium ion batteries commonly in use.
