High performance miniature power sources could enable new microelectronic systems. We report lithium ion microbatteries having power densities up to 7.4 mW/cm2 μm, which equals or exceeds that of the best supercapacitors, and which is 2,000 times higher than that of other microbatteries. The battery microarchitecture optimizes ion and electron transport for high power density while maintaining a high...

The operation of such stations has negative economic and environmental effects related to the high transportation cost of fuels, increasing oil prices and emissions. The replacement of fossil fuelled stations with hybrid ones that combine renewable energy...
