Abstract
Electric and hybrid electric vehicles require lithium-ion cells that: (1) provide at least 150 Wh/kg, 230 Wh/l, 300 W/kg, and 460 W/l; (2) have a life of 1000 cycles at 80 percent depth of discharge; (3) have a calendar life of at least 10 years; and (4) are made with materials costing less than $10/kg. This project will develop a high capacity, long cycle life, nanostructured-silicon/carbon-composite anode material made using low cost materials and processes. Phase I will demonstrate nanoparticulate Si production by low cost processing of commodity materials; demonstrate a strategy for the low cost preparation of high-performing, Si/C-composite, lithium-ion anode material, and model its impact on lithium-ion cell performance. Commercial Applications and Other Benefits as described by the awardee: The low cost Si/C material should have broad commercial applicability in small portable power lithium-ion batteries for consumer electronics and power tools, as well as in large lithium-ion batteries for electric vehicles and hybrid electric vehicles
