All-solid-state batteries are new types of batteries that completely replace the electrolyte with solid electrolytes. Such batteries are expected to gradually achieve mass production in 2026 and beyond.

All-solid-state batteries, with their high energy density and better safety, have attracted much attention in multiple fields such as new energy vehicles, consumer electronics, and energy storage. All-solid-state batteries have stronger performance and safety compared to traditional batteries

Compared with traditional batteries, all-solid-state batteries use solid electrolytes instead of liquid electrolytes, significantly enhancing energy density. The energy density of some products can reach 500Wh/kg, far exceeding the current level of 200-300Wh/kg for liquid lithium batteries. This advancement means that in the same volume, all-solid-state batteries can provide more energy while reducing the battery's volume.

In terms of safety, all-solid-state batteries demonstrate higher thermal stability and non-flammability, with no risk of liquid leakage, significantly reducing the risk of battery self-ignition and explosion at high temperatures. In addition, the chemical stability of solid electrolytes is less affected by environmental temperature, which makes the battery more stable in the event of collision and compression, and significantly reduces the probability of fire.

All-solid-state batteries are classified into three types based on the chemical system of the electrolyte

According to the chemical composition of solid electrolytes, all-solid-state batteries are mainly divided into three systems: polymer type, oxide type and sulfide type. Polymer electrolytes are renowned for their excellent interfacial compatibility with the negative electrode and relatively low shear modulus, but they are limited by their lower ionic conductivity and shorter cycle life. Oxide electrolytes stand out for their broad electrochemical window, excellent thermal stability and air stability, although they lack flexibility. Sulfide electrolytes are favored for their excellent electrical conductivity and thermal stability, but their sensitivity to moisture is a concern. These three electrolytes each have their own characteristics and limitations. Choosing the appropriate material system is crucial for the performance of all-solid-state batteries.

It is estimated that the industrial scale of all-solid-state batteries in China will exceed 100 billion yuan by 2030

The development of China's solid-state battery industry is expected to go through three stages. Firstly, from the nascent stage of 2023 to 2025, this period mainly involves the initial exploration and accumulation of technology. During this stage, it is relatively difficult for all-solid-state batteries to enter mass production and application.

It is expected that from 2026 to 2028, as all-solid-state batteries of different technical routes gradually achieve mass production, the industry will enter a period of rapid growth. During this period, technological innovation in all-solid-state batteries and the gradual mass production of various technical routes will be the main driving forces for the development of the industry.

In 2029 and beyond, the solid-state battery industry will enter a period of structural adjustment. At this stage, as the cost of all-solid-state batteries decreases, it is expected that there will be significant changes in the market structure, and all-solid-state batteries will gradually replace the existing semi-solid-state batteries. Meanwhile, the more cost-effective oxide and polymer routes of all-solid-state batteries may replace the more costly sulfide route products and become the main choice in the market. It is expected that by 2030, the scale of China's solid-state battery industry will exceed 180 billion yuan, among which all-solid-state batteries will exceed 100 billion yuan.

The core of the all-solid-state battery industry chain lies in battery manufacturing enterprises
All-solid-state batteries, as a key energy storage technology, have a complete industrial chain that runs through the entire process from the collection of raw materials to the final application of products. With the continuous technological innovation and the acceleration of industrialization, all-solid-state batteries are expected to play a crucial role in multiple key fields, including new energy vehicles, mobile devices, and large-scale energy storage.

At the core of the industrial chain lies the manufacturing of all-solid-state batteries. Chinese enterprises are actively delving into technology and exploring innovation in this field, dedicated to developing new materials and improving production processes. It is expected that in the coming years, all-solid-state battery technology will witness a series of significant development milestones, achieving a leap in performance and effective cost control.
