In recent years, all-solid-state batteries have almost become the focus of global automobile manufacturing giants, and have even become their important investment field. After years of hard work, they are now on the eve of technological breakthroughs.

At present, BYD's 20ah and 60ah battery cells have fully entered the mass production stage, and the stability can reach 400WH/kg. The market is still in the transition period from semi-solid state to all-solid state batteries, and it is expected that by 2024, some companies will launch solid-liquid hybrid batteries.

Although all-solid-state batteries have been developed, it still takes a period of verification to achieve their industrialization to ensure that their performance indicators meet the requirements, including the energy density must be greater than 350WH/kg and the battery cell capacity is between 20-30Ah.

Vehicle load testing and verification is also needed (2026-2028) to confirm that the materials, structures, processes and technical routes are becoming mature, and at the same time, through testing, its energy density exceeds 400WHkg.

It is expected that by 2027, full mass production and loading will be achieved, and it is expected to be launched on a large scale between 2028 and 2030 to achieve full commercial development.

As soon as the news of BYD was announced, many netizens could not hold back and expressed their expectations for the arrival of 2027.

"When BYD claimed that it would eliminate fuel vehicles, everyone disliked it, but he achieved this goal. This time, I also firmly believe that he will succeed."

"While BYD may not be the first company to launch an all-solid-state battery, it is very likely that most consumers can buy affordable all-solid-state battery cars."

With the automotive industry's high attention to all-solid-state batteries, it has caused people to think deeply. For many years, major automobile companies have been working hard to develop solid-state batteries and explore technological breakthroughs. What are the differences between solid-state batteries and liquid batteries?

All-solid-state batteries are the ultimate form of the development of lithium batteries.

Batteries are very familiar items and are widely used in various industries. Whether it is a watch, laptop, or a mobile phone, it is inseparable from the support of the battery.

At present, lithium batteries are widely used on the market, also known as liquid batteries. The battery industry generally believes that lithium-ion batteries have reached their performance limits. In order to seek higher performance and safer products, solid-state batteries are regarded as the next "successor".

Unlike traditional liquid batteries, it uses glass compounds made of materials such as lithium and sodium, and uses solid compounds as conductive dielectrics, which can significantly increase the energy density, have greater energy storage capacity under the same volume, and has four major advantages.

First of all, lightweight is one of its major advantages. At the same volume, it has a higher energy density, while replacing the traditional liquid electrolyte with new materials (diaphragms and electrolytes account for 25% of the weight), and has also made significant improvements in the material, which can effectively reduce the overall weight.

The second advantage is volume compact. Materials such as electrolytes in liquid batteries account for 40% of the volume. After replacing these materials, the overall volume can be significantly reduced and the battery will be thinner.

Advantage 3: Experience thousands of bending times. It can withstand hundreds to thousands of bends, ensuring that performance is almost not degraded.

Advantage 4: Extremely safe. Regarding electric vehicles, the most worrying thing is its safety. Batteries may trigger reactions in short circuits or high temperatures, which can lead to fires or even explosions. However, comprehensive improvements in materials effectively avoid these problems and there is no need to worry about it anymore.

By comparison, the advantages of the two are obvious. With its density, safety and cycle life, all-solid-state batteries are leading a new round of changes in battery technology.

The solid-state battery industry has entered a golden period of rapid development.

The Chinese Academy of Sciences pointed out that the current focus should be on electrolytes with sulfide as the core, and the technical route of combining high-nickel ternary positive electrodes and silicon-carbon negative electrodes to ensure the energy density of 400whkg and the cycle life exceeds 1,000 times.

According to the current development of solid-state batteries, with the increasing maturity of large-scale production technology, this field has entered a golden stage of development and is expected to achieve small-scale production in 2027.

BYD's technical team revealed that it has started research and development of materials and battery cells and plans to put them into the production line.

In August 2024, BYD proposed a battery-related patent. According to the patent abstract, the technology adopts the design of an interlaced layer, with a solid electrolyte between the negative electrode and the positive electrode, and the outer layer uses ceramic material, which has excellent stiffness and hardness, and also exhibits good cycling performance.

In addition to BYD, GAC also issued a statement saying that they have initially implemented the full-process manufacturing process and plans to load the vehicle in 2026; CATL has increased its R&D investment; and Huawei's solid-state battery patent has also successfully passed the preliminary review. At present, solid-state batteries are developing rapidly and will soon change from ideal to reality.

In order to actively promote the development of the battery industry, Shenzhen has implemented incentive policies in some regions to provide subsidies or one-time rewards to promote its rapid growth.

Between 2026 and 2027, the battery industry will usher in a period of development opportunities and is at a new historical starting point. This is also an important change related to the future evolution of the battery industry.

This is a brand new competition, and companies that can truly achieve mass production will gain a new dominance. Therefore, major automobile companies have made the research and development of solid-state batteries the top priority.

The rapid development of solid-state batteries has made more and more people worry about buying a car. Once solid-state batteries are mass-produced, all-solid-state battery vehicles will become the dominant industry, while traditional liquid-state battery vehicles will gradually be eliminated.

The world is promoting the research and development of solid-state batteries, and mass production is just around the corner?

During the golden period of rapid development of solid-state batteries in China, overseas research and development is also in full swing.

Recently, South Korean battery supplier SK on released a new process, planning to use photon sintering technology to manufacture composite solid electrolytes, which can significantly enhance the reactivity of the electrolyte. In addition, Microvast in the United States released new results in battery research and development in January this year and proposed a bipolar stacking design to ensure safety while achieving high-voltage work.

It is obvious that in the context of technological changes in the battery industry, batteries with higher energy density and safer are gradually receiving attention from the industry.

Major battery manufacturers at home and abroad are competing one after another and entering the "competitive era". With the continuous improvement of performance and the continuous optimization of materials, the battery industry generally expects to usher in a large-scale production capacity release in the next few years.

SK on announced that they are developing two all-solid-state batteries, one of which uses oxide polymer composite electrolytes and the other is a sulfide electrolyte, which is expected to be mass-produced in 2027 and 2029 respectively.

Many Korean battery companies are actively making plans and quickly applying for patents. In 2024, Samsung launched a solid-state battery sample and said it is expected to achieve mass production in 2026.

American engineers say their technology can break through the limitations of traditional battery electrolytes, thereby significantly improving the efficiency of high-voltage operation. Germany's Mercedes-Benz Group announced that it will collaborate with partners to develop this technology and is expected to achieve large-scale production by 2030.

Japan has approved battery R&D projects for companies such as Toyota, Mitsui, Toyo Steel Plate, etc., aiming to support companies in R&D and achieve technological innovation.

Industry insiders believe that the battery industry has entered the semi-solid state stage, and the maximum range of cars has also increased from 450 kilometers to more than 500 kilometers.

Although the production process of solid-state batteries is quite complex and has high manufacturing costs, with the advancement of technology, the expansion of production scale and the optimization of process flow, the cost is expected to drop rapidly and eventually become commercialized. The range of electric vehicles in the future is also expected to increase to 800 kilometers!

Professional institutions expect that with the widespread use of solid-state batteries by 2030, the price of battery cells will drop to 1 yuan per watt-hour; by 2035, the price is expected to further drop to 0.6 to 0.7 yuan per watt-hour.

Let us look forward to the cheap and safe era of solid-state batteries to be realized as soon as possible. At that time, everyone will no longer worry about the battery catching fire!

By the way, if a car with solid-state batteries is launched on the market, would you choose to buy it? Everyone is welcome to leave a message to share their opinions and opinions.
