USTC break the solid electrolyte lithium battery research bottlenecks

Using observations, researchers will be the same of composition and perovskite solid electrolyte amorphous powder on the surface of rich lithium lamellar particles into crystal, successfully implemented in the new compound electrode between the two kinds of solid materials, close contact. After a series of detailed structure and chemical analysis, industrial silicon smelting process, the researchers found that a layer of impurities and high capacity lithium electrode structure is the same. The current mainstream use liquid electrolyte lithium battery, such as a fire safe hidden trouble, and specific volume to store energy co. , LTD. Iso nozzle load, however, the mainstream electrode material is solid matter, panasonic full heat exchanger core life due to the contact between two kinds of solid matter like solid - almost impossible Liquid full contact, currently use a solid electrolyte battery is difficult to achieve good electrode - Electrolyte contact, battery performance is not satisfactory. ” Mr. Ma, said professor to apply this principle to the other important materials may develop better battery performance, chest back to install video raises the more interesting scientific problem. More importantly, the researchers also found that the extension of solid - Solid contact can tolerate a large lattice mismatch, so they put forward the strategy can be applied to a variety of perovskite solid electrolyte and layered electrode. With a solid electrolyte replacement of traditional organic liquid electrolyte of lithium ion battery can greatly alleviate security issues, rural photovoltaic fraud and is expected to break through the energy density & other; Glass ceiling & throughout; 。 Chest backplane installed video results published in top academic journals 'Matter'. “ This work indicates a worth exploring a new direction. Recently, panasonic USTC professor Mr. Ma and total heat exchanger core life partners put forward a new strategy, can effectively solve the next generation of solid state lithium battery electrode materials in contact with a solid electrolyte is poor this crucial question, the solid-state compounds synthesis capacity and rate of electrode exhibited excellent properties. Rural photovoltaic fraud Mr. Ma team and collaborators on a classic perovskite phase structure of the solid electrolyte impurities for atomic observation, while the impurities and solid electrolyte structure is different, but the researchers observed their atoms can be arranged in the form of mutual extension at the interfaces. - solve the electrode Solid electrolyte contact problem, the - Solid compound electrode can and fixed - rate performance Liquid compound electrode.
