Designing Lithium-Ion Batteries To Last
A new electrode design for lithium-ion batteries stores twice as much energy as those found in today’s portable electronics. It also doesn’t degrade when discharged and recharged (Nano Lett., DOI: 10.1021/nl2027684). The design may help battery manufacturers overcome problems that have kept a promising technology from reaching the market.
As lithium-ion batteries’ storage capacity increases, electric cars and smartphones both function longer without needing to recharge. But researchers have had difficulty making high-energy batteries . . .
