Today the world is rapidly adopting electric vehicles, but the biggest challenge before electric vehicles is battery charging and long range. Petrol or diesel vehicles can be refueled in a few minutes, whereas electric cars take a lot of time to charge. Chinese scientists have now claimed to have found a solution to this problem. They have created a new solid-state battery that can be fully charged in just three minutes. The special thing is that this battery not only charges very fast, but is also said to be safer and more powerful than the existing batteries. Scientists of the Chinese Academy of Sciences have created this new high-energy solid-state lithium-metal battery. This research has also been published in the Journal of the American Chemical Society. Scientists say that this technology can completely change the world of electric cars in the future, due to which the charging time will be significantly reduced and the range of the vehicles will increase significantly.
Chinese scientists found the solution
Most solid-state batteries in use today use a polymer electrolyte called PVDF. The problem was that during rapid charging, the chemicals inside the battery would react with each other, causing the battery to deteriorate quickly and reduce its life. Chinese scientists have solved this problem with a new technology. They have created a unique, strong lithium fluoride coating inside the battery, which protects the chemicals inside from getting damaged. This makes the battery safer and lasts longer. The most special thing about this battery is its charging speed. According to reports, this battery can be charged at a speed of 20C, which means it gets fully charged in just 3 minutes. Additionally, it retained approximately 82 percent capacity even after 700 consecutive fast charging cycles. This means that the battery can deliver performance for a longer period of time.
What is the energy density of the battery?
The energy density of the new battery is also very high. Its capacity is stated to be 451.5 Wh/kg, whereas the LFP batteries used in most electric cars today give a capacity of about 200 Wh/kg. Simply put, this new battery can store more than double the power despite being smaller in size. EVs will get its direct benefit in the form of longer range. This battery is also considered very strong from safety point of view. During testing, scientists also hammered an iron nail into the battery, but still the battery neither caught fire nor exploded. This suggests that solid-state batteries may prove to be safer in the future than current lithium-ion batteries.
