(Invited) Electrolyte Design for Li-Ion and Li Metal Batteries

Abstract

The energy density, safety, and cycle life of batteries are critical for electric vehicles (EV), electric aviation, and renewable energy storage. However, current Li-ion batteries still cannot simultaneously meet all the requirements for these applications. We developed non-flammable fluorinated organic electrolytes, aqueous electrolytes, and solid-state electrolytes to form nano-scaled solid electrolyte interphase, which enhanced the energy density, safety, and cycle life of Li batteries. The electrolyte design principle for high-capacity anodes and high-voltage cathodes will be discussed.
