Partnered with Superior Graphite Inc., Hanyang University, Korea (YK Sun), Yang Ren (APS), the Sandia National Laboratory and the Argonne National Laboratory have developed a chemical solution, known as a redox shuttle additive, a chemical that prevents overcharging by electrochemically “locking in” a maximum voltage that is dependent on the chemical structure of the additive and the nature of the battery material.
This innovation prevents plug-in electric vehicles from overcharging their lithium-ion batteries, which can lead to sudden increases in temperature that can potentially start a fire. This technology can further improve the safety of plug-in electric vehicles by electrochemically “locking in” a maximum voltage for the battery that depends on the chemical structure of the additive and the nature of the battery material. The additive was recognized for its progress in the industry and received a 2014 R&D 100 Award.
