报告摘要：

The development of next-generation energy storage devices and systems relies on materials with significantly improved performance and lower cost. The objectives of our research are to enhance energy storage performance (e.g., energy capacity, power density, stability, safety) and to reduce the cost of batteries. In this talk, I will mainly discuss two topics: (1) Electrolyte designs to achieve high-energy density and stable cycling performance in wide temperature range. I will first demonstrate the holistic design of dual-ion batteries, which circumvent the sluggish ion desolvation process found in typical lithium-ion batteries during discharge. These batteries are enabled by a novel ester electrolyte, which simultaneously provided high electrochemical stability and ionic conductivity at low temperature that can enable high-performance Li-ion batteries. (2) Design of energy-efficient recycling and regeneration process for spent batteries. The increasing amount of lithium-ion battery consumption will result in the resource shortage and price increase of lithium and precious transition metals (Co, Ni etc.). In addition, the wastes generated from disposal of used batteries can cause severe environment pollution. This talk will introduce an effective strategy to recycle, and regenerate spent batteries using a “non-destructive” approach, which will lead to new electrode materials that can show the same level of performance as the native materials.
