Battery Manufactory

Electric cars struggle with extreme temperatures, mainly because of impacts on the electrolyte solutions in their lithium-ion batteries . Now, researchers have developed new electrolytes containing multiple additives that work better over a wide temperature range. They report their results in ACS Applied Materials & Interfaces. Lithium-ion batteries are widely used in cell phones, laptop computers and electric vehicles. The electrolyte solutions in these batteries conduct ions between the negative electrode (anode) and positive electrode (cathode) to power the battery. An indispensable component of most of these solutions, ethylene carbonate helps create a protective layer, preventing further decomposition of electrolyte components when they interact with the anode. However, ethylene carbonate has a high melting point, which limits its performance at low temperatures. Wu Xu and colleagues showed previously that they could extend the temperature range of lithium
