Same-size lithium ion battery, 10 times the storage | Cutting Edge - CNET News: With a better anode, a cell phone could be charged in 15 minutes and have 10 times the energy storage capacity of current lithium ion batteries, according to Northwestern University researchers, who predict the technology could be available in three to five years.
Argonne's battery researchers, meanwhile, say that replacing the traditional graphite anode with titanium oxide could lead to cell phones that can get half their full charge in less than 30 seconds.
