The industrialization of solid-state batteries has entered a new stage

It is reported that recently, the first high-capacity all-solid-state battery production line in China has been initially established and has entered the small-batch production testing phase!

The batteries commonly used in mobile phones, electric vehicles, and laptops in our daily lives are primarily liquid lithium batteries. These batteries have a positive electrode and a negative electrode at both ends, with a layer of liquid electrolyte in between. The electrolyte provides a transmission channel for lithium ions, allowing them to move back and forth between the positive and negative electrodes, thus achieving the function of battery charging and discharging.

The solid-state battery mentioned in this article is primarily composed of solid electrolytes, such as lithium-containing inorganic salts, solid polymers, or special ceramic materials. Based on the different proportions of solid and liquid electrolytes, solid-state batteries are simply divided into three types: semi-solid, quasi-solid, and fully solid. In particular, fully solid-state batteries have completely replaced liquid electrolytes with solid electrolytes. This not only significantly enhances the safety performance of the battery but also increases its capacity, making the battery charging process more efficient, faster, and safer. Hence, the days of batteries being "flammable and explosive" have become a thing of the past.

Compared to liquid batteries, the implementation of solid-state electrolytes has significantly improved the performance of all-solid-state batteries!

All-solid-state batteries can theoretically achieve an energy density of 400~500Wh/KG, with a power storage capacity more than twice that of liquid batteries. With doubled battery capacity, users can bid farewell to range anxiety.

The ion high-speed channel achieves a super fast charging mode. Experiments have confirmed that the ionic conductivity of solid-state electrolytes can be more than twice that of liquid electrolytes, which significantly increases the charging speed of all-solid-state batteries.

Moreover, the use of solid-state electrolytes significantly enhances the heat resistance of batteries, with a heat-resistant temperature exceeding 300℃, greatly reducing the risk of fire. At the same time, it addresses the issues of electrolyte leakage and evaporation from the source, mitigating potential safety hazards.

The breakthrough in all-solid-state battery technology will revolutionize various electric vehicles, bringing the dream of thousands of miles of endurance to reality! With the preliminary completion of the first large-capacity all-solid-state battery production line in China, it marks a crucial leap from research and development to industrialization in this core technology field.

After the full-scale industrialization and implementation of all-solid-state batteries in the future, they will have a very broad application prospect in the fields of new energy vehicles and low-altitude economy. In the field of new energy vehicles, they can reduce the spontaneous combustion hazards of electric vehicles, greatly improving safety performance. With a 100-kilogram battery, the driving range is expected to exceed 1,000 kilometers! They can even support new energy vehicles to complete fast charging within 10 to 15 minutes, which is almost as fast as refueling for old-fashioned fuel vehicles.

In the low-altitude economy sector, the world's first flight test of unmanned aerial vehicles equipped with solid-state batteries has been completed. It has been confirmed that the endurance of drones using solid-state batteries has been significantly increased by 60% to 90%. This has led to a qualitative leap in applications such as logistics and crop protection!

Under the attention of all Chinese people and with the day-and-night efforts of relevant technical personnel, all-solid-state batteries are gradually moving from the laboratory to the industrial chain, from the ground to the sky, and into our future beautiful life.
