Colorado State University Spinoff to Commercialize 3D Li-ion Battery Technology for Higher-Capacity, Longer-Life Cells
Green Car Congress
DECEMBER 17, 2009
Examples of prospective 3-D architectures for charge-insertion batteries, as proposed by Long et al. (a) a) array of interdigitated cylindrical cathodes and anodes; (b) interdigitated plate array of cathodes and anodes; (c) rod array of cylindrical anodes coated with a thin layer of ion-conducting dielectric (electrolyte) with the remaining free volume filled with the cathode material (the Prieto Battery approach); (d) aperiodic “sponge” architectures.
