Researchers improve energy capacity of lithium batteries

Researchers around the globe have been on a quest for batteries that pack a punch but are smaller and lighter than today’s versions, potentially enabling electric cars to travel further or portable electronics to run for longer without recharging. Now, researchers at MIT and in China say they’ve made a major advance in this area, with a new version of a key component for lithium batteries, the cathode.  The first version of this new battery yielded a 40% increase in energy density compared to current conventional commercial lithium batteries and with optimization the researchers say it could reach 50% or more.  Read the full article.
