As portable electronic devices such as laptops and smartphones get more robust, consumers would like for batteries to keep pace. But rechargeable batteries -- Lithium-ion (Li-ion) being among the most popular - haven't done that. They are 25 year old technology powering things produced this year. Japanese researchers from a prive sector-government team report an advance in Li-ion battery technology that they describe as a major breakthrough. They fabricated a cathode (positive electrode) of lithium cobalt oxide (LiCoO2) in which the compound's individual grains are aligned in a specific orientation. The researchers claim that this yields a significantly higher-performing battery than one with a randomly-oriented LiCoO2 cathode. read more
