Can the salt bath method extend the life of electric vehicle lithium batteries?

The Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) issued a research report yesterday stating that scientists of the organization have invented a simpler method to extend the life of rechargeable lithium batteries. The organization named this method as salt bath. It is reported that the method was discovered by CSIRO in collaboration with RMIT University and Queensland University of Technology. According to the analysis of CSIRO researchers, the material they used is an ionic liquid, which is also called normal temperature molten salt. It is a transparent, colorless, odorless, and flame-retardant magical liquid. These materials can be displayed on the surface of the electrode. A protective film is formed to keep the battery stable during use. The process and principle of solving the battery is that before the battery is assembled, the lithium metal electrode is immersed in a mixed electrolyte containing ionic liquid and lithium salt. After this solution, not only can the battery life be extended, but also the battery’s life can be extended. With extended battery life, performance and safety can also be strengthened to a certain extent. Electric vehicle lithium battery life: the life of lithium batteries The batteries in electric vehicles that various manufacturers are trying to develop at this stage are basically batteries (mainly lithium batteries) and fuel power batteries. Fuel power batteries are due to high development and protection costs. (The protection cost of fuel power batteries is about three to four times that of batteries), which is not suitable for the development of electric vehicles at this stage. So I won't mention it for the time being, just talk about the lithium battery commonly used today. The service life of lithium batteries in general electronic products is about 5 to 20 years, an average of 8 years, and with the current skill level, the service life of lithium batteries in electric vehicles is only about 3-5 years. When the battery capacity on an electric vehicle decays below 80% of the initial capacity, the driving range of the electric vehicle will be significantly reduced. When the battery capacity decays below 70%, the battery must be replaced. Regarding many pure electric vehicles at present, the cost of the battery accounts for about 40% of the total cost of the car. In other words, replacing the battery is equivalent to replacing a small car. If the electric vehicle charger is normal, and the electric bicycle that travels less than 10km per day, the brand-name new battery can properly make up for the deionized water when the warranty expires. For an electric car traveling 50km a day, you should check the battery condition after 8 months, and make up for the deionized water appropriately. Each compartment should make up 3~4ml, especially in summer, you must remember to cover it after adding water. Safety valve. For electric vehicles that are often used by people, it is recommended that they should be checked for about half a year, and maintenance should be carried out according to the conditions of use. Many users of electric vehicles find that the positive battery is easily lagging behind, because the distributed capacitance between each battery cell and the car body is different, and the positive battery is the most damaged. Swap the middle battery and the side position while adding water, so that the positive battery takes turns to sit in the bank. When the battery level is above 80%, you don’t need to charge it. If it is between 30% and 80%, it will be charged when you have the opportunity. If it is less than 30%, it must be charged. When accelerating, it should be gentle and not overloaded. If you have pedal equipment, try to help you move as much as possible when you start or go uphill. The battery in the battery box should be tightly sealed with paper, and the bottom should be glued with double-sided foam tape if possible to prevent battery vibration. Perform a thorough discharge once a month, and then continuously charge for 12 hours. When replacing the battery, you should always test the parameters of the charger to keep the battery and the charger matched. Once it is found that it is difficult for the charger to turn the green light or turn to the green light as soon as it is charged, and the battery temperature rises abnormally during charging, you should immediately check whether the charger is the problem or the battery problem. Generally, for chargers without temperature compensation, a 6A10 diode is connected in series between the charger and the battery in summer, and two 6A10 diodes are connected in series with the gel battery; in other seasons, short-circuit the diode. Maintain excellent vehicle mechanical skills, adequate tire pressure, excellent smoothness, and normal brake clearance and tightness. By achieving the above 10 measures, lithium batteries can extend their service life exponentially.
