For example, in solar and wind power generation, LICs can effectively balance power fluctuations and provide stable power output. Additionally, LICs can be used in backup power systems for homes and industries, providing reliable power support during outages.

5. Automotive Industry

In the automotive industry, especially in electric vehicles (EVs) and hybrid electric vehicles (HEVs), LICs have broad application prospects. LICs can work in tandem with traditional battery packs to provide instant high power output, improving vehicle acceleration performance and energy efficiency. For example, during vehicle start-up and acceleration, LICs can supply instant high power, reducing the burden on traditional batteries and extending their lifespan. Moreover, LICs can be used to recover braking energy, enhancing overall vehicle efficiency.

6. Communication Equipment

Communication equipment, such as base stations and data centers, require extremely high power stability and reliability. LICs can serve as backup power sources, ensuring that communication equipment operates normally even during main power failures. Furthermore, the fast response characteristics of LICs make them excellent in handling sudden power demands, ensuring continuous and stable operation of communication equipment.

7. Medical Equipment

In the medical field, LICs are used in portable medical devices and emergency equipment. For example, defibrillators require instant high-energy output, and the high power density of LICs can meet this need, ensuring that the device can function quickly in emergencies. Additionally, LICs in portable medical devices can improve portability and lifespan, enabling healthcare professionals to use them in various environments.

8. Smart Home

With the rapid development of the smart home market, LICs are increasingly used in smart home devices. Devices like smart locks, smart cameras, and smart lighting require stable power supplies, and LICs can provide continuous and stable power to ensure these devices operate normally. Additionally, the fast charging capability of LICs allows smart home devices to complete charging in a short time, enhancing user experience.

9. Military and Aerospace

In military and aerospace fields, LICs are used in various high-reliability and high-performance equipment. For instance, military communication equipment, radar systems, and satellites require long-term stable operation, and the long lifespan and high reliability of LICs can meet these demands. Furthermore, LICs can be used in missiles and unmanned aerial vehicles, providing instant high power output and enhancing equipment performance and combat capabilities.

10. New Energy Sector

In the new energy sector, LICs combined with solar panels and wind turbines can improve the efficiency and stability of energy systems. For example, in photovoltaic systems, LICs can store excess energy during the day and provide power support at night or during cloudy days, balancing energy supply. Additionally, LICs can be combined with wind power systems to smooth out power generation fluctuations, improving overall system efficiency.
