Cylindrical Solid-State Battery Applications
Small – scale Power Field: Portable and Wearable Devices, Electric Tools and E – bikes
Portable and Wearable Devices: Their compact size, high capacity, and excellent safety make them suitable for small electronic devices. For example, they can be used as power sources for hearing aids, smart wearable devices, and other healthcare – related electronic products. Unlike traditional batteries, they do not have the risk of liquid leakage or combustion, which is crucial for devices that are in close contact with the human body. Besides, their good durability can reduce the frequency of battery replacement for these small devices.
Electric Tools and E – bikes: applied in electric tools and e – bikes. They address the issues of short battery life and slow charging in traditional electric tools and e – bikes, enhancing their usability.
Emerging Intelligent Equipment Field: Humanoid Robots, Low – altitude Aircraft (eVTOL)
Humanoid Robots: Humanoid robots have strict requirements for batteries, demanding high energy density, high power, and long service life simultaneously. Cylindrical solid – state batteries meet these needs well.
Low – altitude Aircraft (eVTOL): The low – altitude economy sector, represented by eVTOL, has extremely high performance requirements for batteries. The combination of “semi – solid state + large cylindrical” has gradually been applied in the eVTOL market. These batteries can meet the high energy density and high rate performance requirements of eVTOL, laying the foundation for the large – scale development of the low – altitude economy.
Infrastructure and Industrial Monitoring Field
solid-state battery can serve as a power source for status monitoring sensors in factory equipment, infrastructure, and tires. In harsh environments such as resource extraction and offshore development, where temperatures are extreme and battery replacement is difficult, this battery can maintain stable operation for a long time.
Data Center Backup Power Field
The BBU (Battery Backup Unit) of AI data centers has strict requirements for battery safety and stability. Cylindrical solid – state batteries have become an ideal choice for BBU due to their high thermal safety and long service life. In the high – voltage DC power distribution system of new AI data centers, they have high power conversion efficiency, which helps reduce the operating costs of data centers.
Automotive Auxiliary Equipment Field
Although cylindrical solid – state batteries are not yet widely used in the main power supply of automobiles on a large scale, they have shown application potential in automotive auxiliary equipment. Their high safety and durability can ensure the stable operation of automotive auxiliary functions such as on – board sensors and intelligent control systems, preventing malfunctions caused by power supply problems.
