Coating Those Troublesome Lithium Ion Cathodes and Anodes
February 12, 2020 | Leave a Comment
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 […]

Now There Is a Heat Battery Design
November 21, 2017 | 8 Comments
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 […]

Using Paper to Make Supercapacitors
October 11, 2017 | 3 Comments
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 […]
