German Scientists Create A Electric Car Battery With A Lifespan Of 27 Years






The Scientist at the Center for Solar Energy and Hydrogen Research Baden-Wurttemburg (ZSW) has just developed one of the most efficient lithium-ion batteries yet. These batteries are able to retain a 85% charge if they are charged every day for about 27.4 years. This certainly holds a bright future for this type of technology.  


The power density in these batteries are extremely high at 1,100 watts per kilogram, the power density measures the available power per unit of weight. It translates to very short charging times and superior acceleration capability in an electric vehicle. The scientists completed 10,000 complete charging and discharging cycles once every hour this indicates that the batteries will be able to hold their charge for about 27.4 years if they are charged every day.



The study was funded by the German Federal Ministry of Education and Research and the German Ministry of Economics and Technology. The small cells are produced in a plant in the ZSW Laboratory for Battery Technology.
