The biggest problem of new energy vehicles is the lack of mileage and slow charging speed, if you combine these two points, then the most urgent need to improve is the battery-related technology, the performance level of the power battery will be able to greatly improve the performance of new energy vehicles in all aspects.
Nowadays, the industry for the new energy vehicle industry, especially the power battery is the most optimistic is actually the solid-state battery, many manufacturers in the industry believe that the solid-state battery will become the key point of the new energy vehicle "breakthrough", and now there are many new energy vehicle companies and battery manufacturers are accelerating the research and development of solid-state batteries, and have achieved some good results. It is worth noting that a Chinese company recently announced a major breakthrough in the field of solid-state batteries.
Judging from the news it revealed, it has completed solid-state electrolytes, positive and negative electrode materials, integrated molding processes and other technologies, and manufactured all-solid-state lithium metal batteries with an energy density of up to Wh\kg.
If this news is true, then according to the energy density in the field of solid-state batteries today, this battery has set a new record, which can be called the world's highest energy density solid-state battery, and even some batteries that are still under development cannot be compared.
According to the information on the Internet, this Tailan new energy company was founded in 2018 and is an out-and-out young enterprise, established by a team of returnee lithium battery R&D experts, and has received multiple rounds of investment and produced semi-solid-state batteries in 2022.
It has to be said that such an "obscure" Chinese company has suddenly achieved such results, which is really a bit amazing, if this news is true, then it will be possible to completely change today's new energy vehicle industry. AFTER ALL, JUDGING FROM THE PUBLIC NEWS TODAY, THE ENERGY DENSITY OF LITHIUM-ION BATTERIES IS GENERALLY BETWEEN 120WH AND 260WH KG, AND THE SEMI-SOLID-STATE BATTERIES CURRENTLY IMPLEMENTED IN CHINA CAN REACH ABOUT 360WH AND KG, AND THE HIGHEST ENERGY DENSITY IN THE FIELD OF NEW ENERGY VEHICLES IS ONLY ABOUT 400WH AND KG, AND THERE IS NO NEWS OF IMPLEMENTATION.
These are the energy densities of lithium batteries and semi-solid-state lithium batteries currently in use, and in fact, some companies have said that they have completed the research and development of solid-state batteries. FOR EXAMPLE, HUINENG, PANASONIC AND OTHER MANUFACTURERS, BUT JUDGING FROM THE CURRENT PUBLIC DATA, THE ENERGY DENSITY OF SOLID-STATE BATTERIES PRODUCED BY THESE MANUFACTURERS IS ALSO ABOUT 500WH\KG.
From this comparison, we can clearly see the excellence of the solid-state battery of Tailan New Energy in terms of energy density, so what technology is used to achieve such an excellent energy density? At present, this battery has not been officially produced, and Tailan New Energy has not disclosed relevant news.
However, according to some of its patents and some previous introductions and future prospects for semi-solid-state batteries, it can be roughly understood that it should be related to the fields of electrolyte materials and interfacial flexible layer materials. It may be that the contact performance of the electrolyte with the electrode is improved by improving the ion transport efficiency, thereby improving the energy density and charging speed.
Since Tailan New Energy has not yet come up with actual products, it is not known how the battery will perform in actual use, but it is enough to see that the mainland has taken a key step forward in the field of solid-state batteries, and it is likely to continue to maintain a leading edge in the solid-state battery industry in the future.
