Since new energy has gradually become the mainstream of the development of the car market, everyone has paid more and more attention to the research and development of batteries, after all, everyone knows that the biggest stumbling block that hinders electric vehicles from replacing fuel vehicles is that battery technology has not been able to break through. Even if many car companies have made great efforts in the mileage, and some have even achieved more than 1000km, if the problems of battery fast charging technology and battery safety are not solved, then electric vehicles still cannot completely replace fuel vehicles.
For such a situation, car manufacturers and battery manufacturers also understand that Tesla has been stumbling on the 4680 battery, whose storage capacity will be 5 times that of the 2170 battery, and the power is up to 6 times, which is expected to increase the vehicle driving range by 16% and reduce the cost by 14%, once it is mass-produced, it will undoubtedly help Tesla to a higher level. However, in comparison, the industry generally looks better at solid-state batteries as the existence of a truly revolutionary fuel vehicle.
In this context, when solid-state batteries can be mass-produced has become the focus of everyone's attention. Some time ago, Zhiji L6 became popular in the automobile market, not only because it touched the porcelain Xiaomi SU7 and was overturned, but also because the battery it carries is the industry's first quasi-900V ultra-fast charging "solid-state battery", which really makes many people excited. Although it was later confirmed that the ultra-fast charging solid-state battery announced by Zhiji still belongs to the category of semi-solid-state batteries, it can be regarded as a first step.
However, with the development of new energy vehicles, all-solid-state batteries have received more and more attention in the industry, and even the academic community has also reported dynamics. According to the news shared by the Qingdao Institute of Energy of the Chinese Academy of Sciences, a key breakthrough has been made in sulfide solid-state batteries. It is reported that the multi-layer laminated pouch battery prepared by the above-mentioned research team has been cycled 300 times, and the capacity is almost not attenuated, and the performance is still being tested. At present, the research team is preparing for the landing of the 20Ah sulfide all-solid-state battery molding production line, and is cooperating with upstream and downstream industries to take the lead in realizing the mass production of sulfide all-solid-state batteries in 2026.
It is worth noting that the craze for solid-state batteries continues in the past few days, because just this month, GAC Group also announced that it plans to realize the installation of all-solid-state batteries in 2026. And this is one year earlier than Toyota's previous threat of mass production.
As we all know, the current domestic mainstream electric vehicle energy supplement mode is divided into charging and battery replacement. In terms of charging, most electric vehicles use ternary lithium and lithium iron phosphate batteries, which are liquid lithium batteries, and this kind of battery has developed to the present, in fact, there is not much potential to be tapped. As for battery replacement, today's popularity rate is not high, and it also has obvious drawbacks, that is, there is no unified specification and standard for battery development, and the battery size and cost of each electric vehicle are different, and this incompatibility has also increased the development of battery replacement. So if there is a battery with fast charging and long life at this moment, will the "expansion desire" of electric vehicles be stronger?
That's where solid-state batteries come in. Its advantages can be simply divided into four aspects, one is that the charging speed is faster, and the range of electric vehicles can be easily doubled without increasing the weight of the battery. Second, the energy density is high, which means that it can do better in terms of cruising range. Third, the battery is safer, the solid electrolyte is not easy to burn, not easy to burst, no electrolyte leakage, no side reactions at high temperatures, and the safety is greatly improved. Fourth, the battery cycle life is longer, after all, the battery is alive, and the longer it is used, the more the battery will wear out, resulting in a decrease in capacity, while the ideal state of the solid-state battery is better, and the service life of the electric vehicle can be as long as 10 years in theory.
It can be said that solid-state batteries have huge advantages over ternary lithium batteries commonly carried on the market. Especially in terms of range anxiety, compared with the speed of fast charging on the market for half an hour to reach 80%, the fast charging of solid-state batteries only takes a few minutes.
Write at the end
New energy vehicles are a major mainstream of the future automotive industry, and this conclusion should be undisputed. It is precisely because of this that many traditional car companies are transforming to enrich their product strength, and who will achieve a revolutionary breakthrough in the field of batteries, which means that it will be at the forefront of new energy, so are you optimistic that solid-state batteries can be mass-produced and loaded in 2026?
