Lithium-based batteries' tendency to overheat and catch fire has been keeping back the development of promising new technologies. In particular, it's been affecting R&D of lithium-sulfur and lithium-air batteries, both of which are much lighter than current options and can store 10 times more...

Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell -- developed at Harvard's School of Engineering and Applied Sciences -- that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both...

With the modern US soldier turning into a walking gadget, the army has some heavy reasons to lower battery weights. Its own scientists might have the answer, claiming 30 percent energy density jumps could happen using additives they developed. Those "sacrificial agent" materials would bond with el...

Stanford researchers figured out that, by dipping electrodes for super capacitors in a solution of carbon nanotubes or a conductive polymer they could increase the charging capacity by up to 45-percent. The team started working with composite electrodes of graphene and manganese oxide, since mangane...
