Designing better battery electrolytes
You need a positive electrode, you need a negative electrode, and — importantly — you need an electrolyte that works with both electrodes. An electrolyte is the battery component that transfers ions — charge-carrying particles — back and forth between the battery''s two electrodes, causing the battery to charge and discharge.
