Fluoride based batteries might be the answer to longer lasting batteries
Just imagine charging your phone only two times per month - short science news and articles

Researchers have developed Fluoride-based batteries which could potentially last eight times longer effectively reducing the number of times you need to charge your devices. They have developed the first rechargeable fluoride batteries using liquid components that work at room temperatures.

Batteries drive electric currents by shuttling ions between positive and negative electrodes. While, the current lithium-based batteries use positive lithium ions for this, the new fluoride-based batteries use negatively charged ions for the same.

Importantly, it’s more difficult to move the lithium positive ion as compared to the single charged fluoride ion, thereby needing recharging less frequently.
