We've seen hybrid batteries, hairy capacitors, and ultracapacitors, but considering how much we depend on batteries, we're not ones to turn up our noses at yet another new battery development. This latest one comes from researchers in France, who have turned to nanotechnology to create lithium-ion battery electrodes that have several times the energy capacity of traditional electrodes, meaning that batteries could either be significantly smaller or remain the same size and squeeze a whole lot more juice out of a single charge. Of course, one of the many big application for nano batteries is in remote sensors and medical implants, where smaller and longer lasting are definitely better. Which is probably why those smaller-scaled applications are the first we're likely to see, as larger electrodes are currently far less efficient than small ones. Thankfully the researchers at hand believe the technology could eventually be used to power electric and hybrid vehicles, which is always the dream, right?
