According to foreign media reports, BrandonWood, a scientist at Lawrence Livermore National Laboratory (Lawrence LivermoreNaTIonalLaboratory, LLNL), and Mirjana Dimitrievska, a scientist at the National Bureau of Standards and Technology (US), are responsible for leading an international R&D collaboration. The research team found that it is in the electrolyte of lithium batteries. If boron atoms are used instead of carbon atoms, the mobility of lithium ions is improved. For solid-state batteries, this feature is quite attractive.

　　This is an example of the so-called "frustration (frustraTIon)": the dynamics of the system determine that the lithium ion will never be satisfied with staying in place, so the lithium ion will always be in a mobile state.

　　Compared with current batteries, solid-state lithium-ion batteries can improve safety, voltage and energy density. However, solid-state batteries are still in the early stages of research and development. So far, there are few solid-state lithium batteries that can be commercialized.

　　One of the core obstacles to the commercialization of solid-state batteries is that there are too few solid-state electrolyte materials to choose from, which are designed to ensure that lithium ions can effectively move between the positive and negative electrodes.

　　However, there are many problems with the available materials. Some of the materials have problems with stability, and the others are difficult to process. As for the remaining candidate materials, most of them are eliminated because of the slow movement rate of lithium ions, which means When making, make sure that the material is very thin.

　　The new research is mainly devoted to a new material-closo-borates. Recently, it has been found that the lithium ion flow rate of this material is faster. According to Wood, the material has stable electrochemical performance and is easier to process. Compared with other materials, it has many advantages.

　　Although this material also has certain barriers to commercialization, its thermal stability, mechanical strength and cyclability are high, which is precisely the focus of the research team's current focus. This new material is quite attractive and may be used to replace current solid electrolyte materials in the future.

　　The electrolyte material is a salt substance, which contains positively charged anhydrous lithium chloride (lithiumcations) and negatively charged closed borate anions. The study shows that the closed borate anion can quickly complete its reorientation, hovering in the solid matrix, and alternately shifting in a specific preferred direction.

　　If carbon is added to the closed borate anion, a so-called dipole will be formed, which will repel the lithium ions in the nearby carbon atoms. As the anion spins, the carbon atoms will face different positions, each time the lithium ions in the solid matrix will be forced to move to nearby areas. Since these salts are all galloping anions, the flow rate of lithium ions becomes very fast.
