At present, many sources of information are proving that solid-state batteries are expected to be mass-produced in 2026.
At the 2024 GAC Science and Technology Day, two breakthrough technologies were announced - all-solid-state battery and picture-free pure vision intelligent driving system, GAC announced that solid-state batteries have made breakthrough progress, and when the energy density of the battery cell reaches 400Wh/kg, it can meet the safety and reliability requirements of batteries in extreme environments, and is planned to be installed in vehicles in 2026.
In addition, according to the Qingdao Institute of Bioenergy and Process Research, Chinese Academy of Sciences, the advanced energy storage materials and technology research group of the institute has made new progress in the research of sulfide electrolyte, solved the industry pain points and bottlenecks of the sulfide all-solid-state battery tandem process, opened up the last difficulty in the manufacturing process of large-scale vehicle batteries of sulfide all-solid-state batteries, and made a key breakthrough in the sulfide pouch battery lamination technology.
The multi-layer laminated pouch cell prepared by the above research team has been cycled 300 times, and the capacity is almost not attenuated, and the performance is still being tested. Strive to take the lead in realizing the mass production of sulfide all-solid-state batteries in 2026.
Judging from the current information, solid-state batteries are expected to achieve mass production in 2026. And the mass production of solid-state batteries means a lot.
First of all, the end of fuel vehicles has been completely announced. Perhaps compared with the current electric vehicles, fuel vehicles still have residual advantages, that is, fast energy replenishment time, lower spontaneous combustion rate, longer service life, but after the emergence of solid-state batteries, these advantages will disappear completely, solid-state electrolyte is the core of solid-state batteries, in terms of power density, fast charging performance, cycle stability, safety performance, high and low temperature performance and service life have been greatly improved. Think about it, when electric vehicles are charged almost as fast as gasoline vehicles are refueled, what are the advantages of gasoline vehicles, especially in the context of high oil prices.
Secondly, the range extender and plug-in hybrid models, but also lost the meaning and value of existence, the existence of these two types of models, in fact, to put it bluntly, is to solve the battery life anxiety of pure electric vehicles, both no range anxiety, and can drive in urban areas, enjoy the low cost and excellent texture of pure electric drive, but with the mass production of solid-state batteries, electric vehicles almost no range anxiety, at this time, range extender and plug-in hybrid models in order to solve the range anxiety and add the internal combustion engine, but become a drag, every year it needs to be maintained, Change the oil filter of the engine.
Therefore, the mass production of solid-state batteries, will completely change the current status quo of the domestic new energy vehicle market, can be called the subversion of the existence of the entire industry, of course, the mass production of solid-state batteries, but also need to solve the problem of cost, otherwise even if mass production, but can only be carried on high-end models, that can not achieve the effect of subverting the industry, the current sulfide solid electrolyte cost is about 10 times that of liquid electrolyte, but sulfide electrolyte in conductivity and interface impedance performance better, the future is expected to reduce costs through industrial chain optimization, become an ideal choice for all-solid-state batteries。
It is foreseeable that the next few years will be a critical stage for solid-state batteries, so to speak, who can take the lead in realizing the mass production of real solid-state batteries, then who can occupy a greater initiative in the era of electric vehicles.
