　　This is an example of what is called frustration: the dynamics of the system dictate that lithium ions are never content to stay in place, so they are always on the move.

　　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, and so far, there are few solid-state lithium batteries that have been commercialized.

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

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

　　The new research focuses on new materials called closo-borates, which have recently been found to have a faster flow rate of lithium ions. According to Wood, the material has stable electrochemical properties and is easier to process. Compared with other materials, it has many advantages.

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

　　The electrolyte material is a salt substance containing positively charged anhydrous lithium chloride (lithiumcations) and negatively charged closed borate anions. This study shows that closed borate anions can quickly reorient their positions, wander within the solid matrix, and alternately shift according to a specific preferred direction.

　　Adding carbon to a closed borate anion creates a so-called dipole, which repels lithium ions from nearby carbon atoms. As the anions spin, the carbon atoms will face different positions, each time forcing the lithium ions within the solid matrix to move to nearby areas. Since this type of salt is full of galloping anions, the flow rate of lithium ions becomes very fast.
