The problem with electric cars these days is that their lithium-ion batteries need to be replaced every few years, with some costing in the upwards of $10,000+. Researchers at the Center for Solar Energy and Hydrogen Research Baden-Wurttemburg (ZSW) have developed one of the most efficient lithium-ion batteries yet, and in an electric vehicle they’re expected to retain 85% of their capacity after being charged every day for “about 27.4 years.”

According to Inhabitat: “After 10,000 complete charging and discharging cycles, with a complete charge and discharge cycle per hour, these lithium-ion batteries still retain more than 85% of the initial capacity. This means that an electric car with those batteries could be fully charged every day for about 27.4 years and still be going strong. The power density of these batteries, which measures the available power per unit of weight, is also very high at 1,100 watts per kilogram. For an electric vehicle, this means short charging times and a superior acceleration capability.”
