Lithium-ion batteries will face obsolescence?

Now it is the 'winter of the twelfth lunar month' and it is also the coldest time of the year. For new energy car owners, this is not a 'good season'. Because at this time, the cruising range of new energy vehicles will be greatly reduced, making the already poor new energy vehicles 'worse.' Regarding the problem of worsening battery life of electric vehicles in winter, Dai Kangwei, deputy dean of BAIC New Energy Research Institute, gave a specific explanation at the sharing meeting on December 23, 2020. He mentioned that the reason why electric cars have poor battery life in winter is because in cold weather, the electrolyte inside the car's lithium-ion battery will become extremely viscous, resulting in reduced activity and poor battery performance. And unlike fuel vehicles using engine waste heat for heating, in the cold winter, new energy vehicles can only rely on batteries for heating, which undoubtedly greatly accelerates battery power consumption. Therefore, in this case, new energy vehicles will become abnormally power-consuming, which greatly affects the travel of car owners. The point is that if car owners do not charge in time in winter, it is easy to cause electric vehicles to 'break down' halfway, so the battery life of electric vehicles has been criticized by people. Of course, due to the limitation of lithium-ion battery technology, the 'poor battery life' and 'difficult charging' of new energy vehicles have always been our usual topics. It is only the advent of winter, which magnifies the shortcomings of new energy vehicles and makes owners ' Suffering is beyond words'. However, the 'good day' for new energy car owners may be coming, because 'super batteries' are coming out. Super battery 'come out' and 'sling' traditional lithium-ion batteries. At the end of September 2020, a start-up company from Estonia and the Karlsruhe Institute of Technology in Germany announced the completion of the research and development of super battery technology. New energy vehicles, so this battery is also called 'electric vehicle super battery.' It is reported that this battery is made of 'graphene' material with high hardness and strong conductivity, so the charging speed and lifespan of this super battery are very 'abnormal'. According to the analysis of relevant personnel, a traditional electric vehicle lithium-ion battery generally takes 6 to 8 hours to fully charge, and its service life will be greatly reduced within a few years, and the charging effect is even less than 80% of the past. The 'super battery' can be charged within 15 seconds. What's more amazing is that after hundreds of thousands of charging and discharging, its charging effect will hardly be attenuated, the service life is very long, and it is not easy to age. It is conceivable that if a new energy vehicle is replaced with this super battery, then there is no need to worry about 'poor battery life and difficulty in chargingMoreover, because the super battery has a very long service life, car owners no longer have to replace the battery frequently. It may not be a problem for a super battery to use an electric car to 'scrap'. It is known that the manufacturing company of this super battery has signed a 1 billion euros letter of intent for cooperation with an electric vehicle company, and said that the battery will be launched on the market in three years. I believe that if this super battery technology is successfully developed and mass-produced, then the new energy vehicle industry will usher in a 'brilliant and brilliant' future, and today's fuel vehicles will completely become history. However, although the super battery is good, there are drawbacks. Of course, from a rational point of view, we should not trust this 'super battery' too much. As mentioned above, the battery has not been officially launched on the market and is still under development. Therefore, it remains to be seen whether its specific use effect is really as 'perverted' as analyzed. And this super battery does still have defects, not as 'perfect' as everyone thinks. Because according to the analysis, the energy density of this super battery is very low. If you want it to meet the normal power consumption of new energy vehicles, it must be solved by increasing the capacitor bank, which will undoubtedly increase the volume of the battery. And another drawback of this battery is that it cannot be used for long-distance travel because it cannot store energy for a long time, so it can only achieve short-distance travel for electric vehicles. In addition, the super battery has a fatal disadvantage, that is, the price is 'expensive.' Because the graphene used in the battery is a very rare material, it can only be processed in small batches at present. It is known that the current price of high-purity graphene has reached more than 5,000 yuan per gram, which is almost more expensive than gold. Therefore, even if the super battery is successfully mass-produced, the price may not be acceptable to the general public. Therefore, on the whole, although the function of this super battery is 'against the skyObserved. However, optimistically speaking, I believe that since the super battery has been 'impressiveThe solution. The 'spring' of new energy vehicles may really come.
