Huawei's all-solid-state battery has surfaced, achieving a major technological breakthrough!

Both car companies and consumers are looking forward to the arrival of all-solid-state batteries, because solid-state batteries can solve the "pain points" of electric vehicles, such as "range anxiety", low safety, short service life, low charging efficiency, etc. The energy density of solid-state batteries is at least 2-3 times that of lithium iron phosphate batteries and ternary lithium batteries. This means that under the same volume, its pure electric range will be 2-3 times higher. For example, a battery with a pure electric range of 600km can be replaced with a solid-state battery. The pure electric range can reach 1200-1800km. Car owners will naturally not have "range anxiety" when driving such a car.

Current power batteries all use liquid electrolytes, which are active, but there are risks of short circuits and leakage. Many battery fires and explosions are related to the overly active nature of liquid electrolytes. Solid-state batteries use solid electrolytes, which have poorer conductivity, are less active, and will not short circuit or leak, greatly improving safety.

In terms of service life, the current design life of power batteries is about 3,000 cycles of charge and discharge, while the design life of solid-state batteries is at least 10,000 cycles of charge and discharge, which more than triples the service life.

There is also charging efficiency. In fact, the fast charging time of current high-end power batteries can be achieved in 15 minutes, and what about solid-state batteries? It can shorten 15 minutes to 5 minutes! The charging experience is almost the same as the refueling experience.

It is precisely because solid-state batteries have solved the "four major shortcomings" of power batteries that a large number of car companies and related companies have been working day and night to overcome technical difficulties. The main technical difficulty of solid-state batteries is that solid electrolytes are inactive and have poor conductivity. Car companies are trying to improve the conductivity of solid electrolytes.

Huawei recently announced a patent for an all-solid-state battery. The name of this patent is "Doped sulfide materials and preparation methods, lithium-ion batteries." Huawei increases the activity of solid electrolytes by doping sulfide materials. The preparation method has been successful in the laboratory and has verified its feasibility, achieving a major technological breakthrough!

For the entire industry, Huawei's solution has very important reference value and provides strong support for domestic solid-state batteries, which is bound to promote the further development of solid-state battery technology.

After doping with sulfide materials, the energy density, cycle life, stability and safety of solid-state batteries have been greatly improved. Perhaps the solid-state battery research and development of many companies is stagnant due to the lack of "inspiration". Isn't doping with sulfide materials to increase the performance of solid-state batteries a good source of inspiration?

In addition to Huawei, among domestic brands, BYD, Changan, SAIC and Dongfeng Group have also made great progress in solid-state battery technology. Among overseas brands, Toyota, Volkswagen and BMW also have their own solid-state battery plans. According to the current progress, among these car companies, solid-state batteries will be officially mass-produced in 2025 at the earliest and 2030 at the latest. In other words, in the next 6 years, solid-state batteries will be fully popularized and applied.

Many consumers are driving fuel vehicles now in order to wait for solid-state batteries to be installed. Electric vehicles equipped with solid-state batteries will be available as early as 2025. However, the price of such vehicles will not be cheap at the beginning. If you can wait for two or three more years, the price will fall after solid-state batteries are fully popularized. In the next six years, all electric vehicles should be equipped with solid-state batteries. If they are not equipped with solid-state batteries, no one will consider them. Finally, what do you think of solid-state batteries?
