Small Powerful Microbatteries

Size, weight and power limitations have been holding back some areas of technology, like electric vehicles. New, fast charging, lithium ion microbatteries may be about to change that. Small in size, big on power: New microbatteries a boost for electronics – [illinois.edu] Though they be but little, they are fierce. The most powerful batteries on […]

Aluminum Celmet Batteries

Celmet (cell+metal) is a porous, metallic mesh that is conductive and can store electric charge. Sumitomo Electric (SEI) has previously produced celmet using nickel based alloys, but now is producing an aluminum version that can triple the capacity of current lithium-ion batteries. This could also allow the creation of smaller and lighter batteries. Development of […]

1800 – voltaic pile (battery)

A voltaic pile is a group of galvanic cells that are joined together as a circuit in series, forming an electric battery. While it is possible that primitive batteries were in use for several thousand years prior, Alessandro Volta, assembled the first well documented working battery. Volta was following up on Luigi Galvani’s famous experiment […]

Paper Batteries

By coating paper with an ink that contains both carbon nanotubes and silver nanowire, the paper can store an electric charge, allowing it to function as a light and flexible battery or supercapacitor. At Stanford, nanotubes + ink + paper = instant battery – [stanford.edu] Stanford scientists are harnessing nanotechnology to quickly produce ultra-lightweight, bendable […]

Printed Supercapacitor

Supercapacitors that can be printed on a flexible substrate similar to paper or cloth fabric can be used in place of conventional batteries in a variety of new applications. A New Way to Create a Super Capacitor – [eepn.com] Silk screen printing is a familiar process used to print T-shirts, stickers, textiles and circuit boards. […]
