The new solid-state lithium battery can be used safely at a high temperature of 100 ℃

This new type of solid-state lithium battery can be used safely at 100°C. Lithium batteries are already ubiquitous in daily life (electric cars and mobile phones can be seen everywhere), but researchers are still working on safer versions. Lithium batteries are known for their small size and large capacity, but their simplicity can cause problems at high temperatures. Replacing flammable liquid electrolytes with solid electrolytes to prevent spontaneous combustion may be a way to solve this problem. Researchers have just proposed a possible answer, which is a solid-state lithium battery that can withstand high temperatures of 100 degrees Celsius without catching fire. At that time, the battery worked well at 95°C (203°F) and above. Even if you don't have the experience of putting your phone in the sun, you will remember the heat warning on the screen, such as continuing to use the phone after it has cooled down. This is because the liquid electrolyte in the battery can expand or ignite at high temperatures. Improper charging and overheating may be one of the reasons for this type of problem. The probability of lithium battery failure is not high, but the total number of lithium batteries in the world is still impressive. Of course, you don't want such an accident in your iPhone or the electric car in your car. Researchers hope that by using built-in smart chips to monitor the health of lithium batteries and possibly replacing liquid electrolytes with solid-state components, lithium batteries will become safer. The electrolyte is filled between the positive and negative electrodes, and the solid-state battery is obviously more resistant to high temperatures, although this concept raises the question of how to connect the solid-state electrode to the solid-state electrolyte, allow the charge to move, and reduce the resistance and charging time as much as possible. Researchers at the Swiss Federal Institute of Technology Zurich have proposed a battery design that claims to be able to solve this problem. They compared the new battery to two slices of bread sandwiched between electrodes on a sandwich, with a layer of meat as a solid electrolyte in the middle. Garnet is the mineral that makes up most gems and is used as an abrasive in waterjet cutting. It has the highest known lithium ion conductivity. The team crafted a solid garnet electrolyte to take advantage of its porous appearance. The viscous negative electrode allows it to enter the pores, so the contact area between the electrode and the electrolyte is very large, which means that the battery can be charged faster. In the test, the research team found that this battery can withstand high temperatures of 100c (212f). At this time, the best working temperature of the battery is above 95°C (203°F), which is beneficial to the movement of lithium ions. From the perspective of use, it is also suitable for the layout of energy storage power stations. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
