#ENERGY: "3-D Battery Boost Power & Energy Density"
Usually power-density and energy-density--the amount of current it can deliver and the battery lifetime--must be traded off when storing electricity. Battery's trade off lower-power for longer life, whereas super-capacitors trade-off shorter life for higher power, but now University of Illinois-Urbana researchers are claiming the best of both worlds. Their three dimensional (3-D) electrodes simultaneously boost the power- and energy-density of lithium ion batteries albeit only for very small cells, such as those powering implanted medical devices: R.
