Abstract:
Li-ion batteries are the critical enabling technology for the portable devices, electric vehicles (EV), and renewable energy. However, the safety of current batteries still need to be improved to satisfy these requirements. We systematically investigated the electrochemical stability window of the electrolytes, interface/interphase stability and resistance between electrodes and electrolytes. The critical issues limiting these safe electrolytes will be discussed.
