Rice University engineers have built full lithium-ion batteries with silicon anodes and an alumina layer to protect the cathodes from degrading. By limiting their energy density, the batteries promise excellent stability for transportation and grid storage use. The slim layer of the metal oxide applied to common cathodes by engineers at Rice University’s Brown School […]

Chalmers University of Technology and the National Institute of Chemistry, Slovenia have new concept for an aluminum battery has twice the energy density as previous versions, is made of abundant materials, and could lead to reduced production costs and environmental impact. The press release offers the idea that it has potential for large scale applications, […]

Massachusetts Institute of Technology researchers have created a material for a chemical heat ‘battery’ that could release its energy on demand. The new phase-change material provides a way to store heat in a stable chemical form, then release it later, on demand, using light as a trigger. A good example for its use is that […]

Georgia Institute of Technology researchers have developed a paper-based flexible supercapacitor using a simple layer-by-layer coating technique that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities – and the best performance so far in […]

University of Delaware researchers have demonstrated a new polysulfide entrapping strategy that greatly improves the cycle stability of Lithium Sulfide batteries. This may be significant as the energy density of lithium-sulfur (Li-S) batteries is five times higher than that of Lithium-Ion (Li-ion) batteries. Rechargeable Li-ion batteries are the power behind most modern portable electronics. But […]
