Developed Li-ion battery with solid electrolyte

Today lithium-ion batteries have received the most widespread, they are used everywhere – from almost any electronic gadget and ending drones and carts. Researchers at ETH Zurich have developed a new type of lithium-ion rechargeable battery that 100% is composed of solid chemical elements and is not flammable.





In lithium-ion, as in most other batteries, the positive and negative poles — two electrodes — made of solid conductive substances. The charges move between them through the liquid or gelatinous electrolyte. If you charge a battery incorrectly, or leave it in the sun for a long time, the liquid can be ignited in a gel to swell.

With panels of solids that could never happen. "Solid electrolytes do not ignite when heated to high temperatures or in the sun," explains Professor Jennifer Rap, leader of the study.





Swiss scientists have created a battery pack, consisting of a layer containing lithium, serving as a solid electrolyte between two electrodes. The resulting battery can operate at room temperature, but best of all, they operate at 95 degrees Celsius and above. "Then you better move lithium ions in the battery," says Professor Semih Afyon.

"These batteries can completely change energy storage in portable electronic devices," says the Professor of Rap. The next necessary step is the optimization of the battery with a focus on increasing conductivity between the electrodes and the electrolyte.published
