Analysis of the development prospects of all-solid-state batteries

The battery industry has not developed much over the years. Smart phone technology is advancing by leaps and bounds, and electric vehicles are becoming more and more popular, but the capacity of lithium batteries is limited, which means that battery life and the range of electric vehicles are still a dilemma. The class is waiting for a new skill to save them. You might think of graphene, or hydrogen fuel power batteries? Not so. Currently, another technology called all-solid-state batteries can save the battery industry faster. The Cockrell School of Engineering at the University of Texas at Austin announced today that their research team has made a major breakthrough in all-solid-state battery technology: they have developed a low-cost, non-combustible, all-solid-state battery. This battery has excellent performance in energy density and charge and discharge efficiency. According to the university, the energy density of the new battery tested in the laboratory is three times that of the existing lithium battery. This time, the 94-year-old John Goodenough, one of the inventors of lithium batteries, has made a major breakthrough in the battery industry. He and his partner Maria Braga (Mariabraga) lead the team. Professor Gudnov discovered in 1979 that lithium cobalt oxide can be used as an electrode to significantly increase the energy density of lithium batteries, which has become the foundation of the lithium battery industry. He joined the University of Texas at Austin in 1986 and has been engaged in teaching and research ever since. Today, most batteries are liquid (electrolyte). However, there are still defects in the use of liquid batteries, such as the phenomenon of swelling of the package. After many accusations, such as low phenomena, if the extra voltage and current are not strictly charged, the electrolyte will undergo metal-whiskers phenomenon, which will cause the battery to short-circuit. Even fire and explosion. According to the meaning, solid-state batteries use solid electrolytes. The core of the Gudnov team's technology is a glassy solid electrolyte made of alkali metals (importantly sodium and lithium). In the laboratory, after the new battery shows a minimum loss of 1, the 200-year charging cycle has high environmental tolerance, and it can operate from 60 to minus 20 degrees Celsius. If you use a mobile phone, the iPhone may no longer have the opportunity to shut itself down. Winter, right? But for now, the first prospects for new batteries will still be electric vehicles and industrial-grade energy storage devices. In order to popularize electric vehicles, battery cost, safety, energy density, charging efficiency and cycle life are all very important. We believe that this new discovery will solve many problems that batteries could not solve at the time. Mr. Gudnov said. LesNichols, director of the Skills Commercialization Project of the Patent Licensing Department, told PingWest that this new battery, which was completely independently developed by the university team, has been tested in the laboratory and is ready for prototype development. In fact, solid-state battery technology has long been born, but in the past it has been placed by the industry due to the high cost of mass processing. Similarly, Mr. Gudnov’s new breakthrough is not ready to be put into processing, and the remaining problems are left to the universities and industry to solve. The good news is that the school is currently applying for patents and plans to license these skills to battery manufacturers. Nichols estimates that new solid-state batteries will be available within 18 to 24 months. The first product to market may be button batteries, and more will be available soon. In the consumer electronics industry, Apple applied for its own all-solid-state battery patent in 2015; in the automotive and power fields, Toyota, Volkswagen and Bosch are all studying solid-state batteries. It seems that until the size of fuel power batteries is small enough to make graphene batteries feasible, all-solid-state batteries should be the only hope for the battery industry.
