The new ionic liquid electrolyte has a reversible capacity of 2200mAh/g.
The new ionic liquid electrolyte has a reversible capacity of 2200mAh/g. Giovanni B. Appetecchi of the Italian National Institute of New Technologies, Energy and Environment tested the electrochemical properties of binderless Si and Ge nanowire (NW) anodes by properly combining PYR13TFSI and PYR13FSI IL with LiTFSI lithium salt to form an ionic liquid electrolyte. . The Si and Ge nanowire anodes exhibit excellent cycle performance in the ionic liquid electrolyte. Rechargeable lithium batteries are the preferred energy storage system for many technologies due to their high weight and volumetric energy density. However, requirements for lithium ion battery (LIB) charging capacity and energy density, such as automobiles, renewable energy storage, smart grids, and consumer electronics, are increasing. Silicon has a maximum specific capacity of 3579 mAh/g, and helium can provide a specific capacity of 1384 mAh/g, making it the most promising candidate for graphite replacement. Co...
