How to make the battery safer?

There are three important strategies to improve batteries: prevent the use of flammable liquids as solid batteries; make battery components fireproof; and slightly modify the existing functional characteristics of the battery. At least as far as the battery is concerned, this change may come slowly. Regarding the problem of battery fires, one solution that has been hyped up is solid-state batteries. The idea is simple: use solid materials as electrolytes instead of flammable liquid electrolytes; solid batteries are unlikely to catch fire. But the movement of ions in solids is more difficult than in liquids, which means that solid batteries are difficult to design, expensive, and may have performance problems. There are three important methods for manufacturing solid-state batteries. Michael Zimmerman, a materials scientist at Tufts University and founder of solid-state battery company Ionicmaterials, explained that you can use ceramics, glass or polymers to make electrolytes. Ceramics and glass are easy to embrittlement, and once you apply pressure, they can easily break. In addition, they are difficult to produce in large quantities, and toxic gases are sometimes emitted during the manufacturing process. In terms of polymers, some can conduct ions, but they usually only work at extremely high temperatures. Zimmermann's team developed a polymer that can conduct ions at room temperature, but is also a flame retardant. Now, Ionicmaterials is cooperating with battery manufacturers, and Zimmerman hopes to make such batteries in the next two to three years. Another strategy for seeking safer batteries is to make the electrolyte itself fire-resistant, even though it is still liquid. Surya Moganty (SuryaMoganty) is the Chief Technology Officer of NOHMs Technologies. They are developing electrolytes using ionic solids, which are similar to salt but liquid at room temperature. Putting this material in the electrolyte will make them a flame retardant, but again, battery life can be problematic. NOHMs company is improving the formula, the goal is to make the battery using its technology can last 500 cycles. Now, the most effective strategy may not be to drastically change the battery design and reshape the battery, but to study the existing characteristics of the battery and then improve it little by little. For example, the battery already includes a battery management system, which is used to monitor the battery's operation and detect whether there is a problem. A beneficial solution is to make this type of system better. After all, the management system is already part of every battery, and manufacturers should not look for innovative and costly ways to integrate new technologies. Companies can use advanced sensors or other methods to collect battery data, especially in large equipment where the battery system consists of thousands of batteries. Battery research institute NavigantResearch analyst Ian McLenny (IanMcClenny) pointed out that the ability to accurately locate batteries that do not meet the standard will help extend battery life.
