Samsung and MIT to develop solid-state electrolytes provide unlimited capacity for the battery
According to foreign media reports, Samsung and MIT researchers have developed a new basic battery components materials. They said the new material provides almost unlimited battery capacity for storage.
This new material is a solid electrolyte, not only to extend the battery life, but also increase the battery capacity and improve safety. Liquid electrolyte is the primary cause of battery fire.
In addition to the Massachusetts Institute of Technology, scientists at Samsung's Institute of Technology, the University of California, San Diego, and the University of Maryland also participated in the project.
Currently common lithium-ion batteries use liquid electrolytes. Liquid electrolyte is an organic solvent that is the "culprit" in cars, commercial airliners and mobile phones that overheat and catch fire.
With solid electrolytes, the battery will no longer be a safety issue. Gerbrand Ceder, a material science and engineering professor at the Massachusetts Institute of Technology, one of the key researchers in the new material, said, "You can throw the battery on the wall, nail the battery, the battery There is no substance that can burn. "
Sed said the batteries that use solid-state electrolytes will hardly degenerate, meaning the batteries can use "hundreds of thousands of cycles." The electrochemical stability of organic electrolytes is limited, which means that over time they lose the ability to generate charges.
The researchers said solid-state electrolyte is an improvement on current lithium-ion batteries. Electrolyte is one of the three major components in a battery. The other two components are the anode and the cathode.
Previous problems with solid electrolytes are that they do not deliver ions fast enough to generate enough electrical energy. MIT and the Samsung team said they solved the problem.
Another advantage of solid-state lithium-ion batteries is that they can be used normally at very low temperatures. Sed said the solid electrolyte is "a real game changer" that can be used to make "near-perfect batteries."
