MoS2/Graphene Composite Materials As High-Performance Anodes For Li-ion Batteries

May 22, 2011

A pair of researchers from Zhejiang University (China) have synthesized layered MoS2/graphene (MoS2/G) composites using a facile biomolecular-assisted process for use as high-performance anode materials in Li-ion batteries. The MoS2/G composite with a Mo:C molar ratio of 1:2 exhibited the highest specific capacity of ~1100 mAh/g at a current of 100 mA/g, as well as excellent cycling stability and high-rate capability. In a paper published in the journal ACS Nano, researchers Kun Chang and...

Scientists Invent 30 Year Continuous Power Laptop Battery

Betavoltaic batteries sound Nuclear they’re not, they neither use fission/fusion or chemical processes to produce energy.

Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years. Although betavoltaic batteries...
