TECHNOLOGY DESCRIPTION
This invention provides highly scalable methods to fabricate 3-D lithium ion microbatteries and high surface-area electrodes for microbatteries. The methods involve imprint patterning nanoparticle-based inks using nanoimprint lithography to form high surface-area electrodes and 3-D microbatteries with well-engineered architectures. The 3-D microbatteries offer superior performance with greatly enhanced capacity and power, and can be rapidly charged and discharged.
