Direct Printing of 3-D Microbatteries and High Surface-Area Electrodes
• 3-D microbatteries with high power and energy densities
• High surface-area electrodes for microbatteries
• Highly scalable fabrication process
• High surface-area electrode designs to greatly enhance battery capacity and power
• Superior performance
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.
