Longer-lasting lithium-ion battery for cell phones

MIT Technology Review : To power portable electronic devices to last twice as long between charges, a company called SolidEnergy is developing a new lithium-ion battery. Among its innovations is an ultrathin metal anode composed of lithium-metal foil on copper and a combination solid and liquid electrolyte. The lithium increases the battery’s storage capacity, and the high-efficiency electrolyte inhibits the lithium’s ability to react with it, which improves the flow of electrical current. The battery is nonflammable and nonvolatile, works at room temperature, can be recharged up to 300 times while retaining 80% of its storage capacity, and can be manufactured with existing battery production processes.
