Crab Shell Material Used to Boost Lithium Ion Batteries

Mila Luleva — Tue, 25 Jun 2013 12:13:48 +0000

Scientists from Stanford University developed a nanostructures from crab shells, containing sulfur or silicon, which have the potential to increase energy storage capacity of lithium-ion batteries, by allowing free expansion of the electrodes. The latest research in the field of material science seems to be heavily focused on finding the cheapest and most environmentally friendly […]

Yi Cui’s New Silicon Nanotube Batteries Can Get Recharged Up to 6,000 Times

Guest Contributor — Wed, 16 May 2012 13:34:35 +0000

Yi Cui, a Stanford scientist and founder of Amprius, is working on a high-tech lithium ion battery that could last for 6,000 charge and discharge cycles – all without degrading itself below 85 percent. This could bring an end to the headaches that many go through with aging laptop batteries or electric cars which just […]

Amprius's Silicon Nanowire Batteries Seek Faster Manufacturing Processes For Lower Price

Ovidiu Sandru — Sat, 18 Sep 2010 08:07:45 +0000

Complaints about laptops whose charge lasts too little, or about electric cars not being able to charge as quick and last as long as gasoline are frequent. Amprius, a US-based company, addresses these issues and develops a battery that they say it can hold double the charge of regular lithium ion batteries.
