Lithium salts enhance the power of batteries but also increase their cost. A new electrolyte with a very low concentration of the lithium salt LiDFOB could offer a cheaper and more sustainable option.

Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance, as reported by a research team to the journal Angewandte Chemie. In addition, the electrolyte could facilitate both production and recycling of the batteries.
