What is a super capacitor? According to Liu Youmei, an academician of the Chinese Academy of Engineering and director of the expert committee at CSR Zhuzhou Machinery Co., Ltd., in simple terms, it's the third generation of energy storage devices. The first generation involved mechanical energy storage, like flywheels and springs, while the second generation was chemical energy storage, such as lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries. The third generation, however, is based on physical energy storage, with super capacitors being a prime example. Compared to traditional batteries, which typically have less than 10,000 charge cycles, take several hours to charge, and carry risks of explosion and environmental pollution, super capacitors can endure up to one million charge cycles, charge in just seconds, and are completely safe and eco-friendly. This makes them a game-changer in energy storage technology. Dian Dianbo, vice director of the technical center at CSR Zhuzhou Machinery Co., Ltd. and director of the Ningbo Supercapacitor Research Institute, used comparative images to highlight the advantages of super capacitors over conventional batteries. These visual demonstrations clearly showed how super capacitors outperform traditional energy storage systems in terms of efficiency, durability, and safety. The applications of super capacitors are vast and varied. According to Dian Dianbo, they can be widely used in consumer electronics, rail transit, urban public transportation systems, national defense, aerospace, cranes, power generation, and smart grids. One notable example is in port operations, where large cranes lift heavy containers and consume significant amounts of electricity. Traditionally, the energy released when the crane lowers the container is wasted through resistors. However, by using super capacitors, this potential energy can be recovered and reused, achieving up to 80% energy efficiency. This not only reduces energy consumption but also significantly improves environmental sustainability. Due to their green, energy-efficient, and environmentally friendly characteristics, countries such as South Korea, the United States, and Japan have invested heavily in supercapacitor research in recent years. Globally, there are more than a dozen manufacturers producing various types of supercapacitors, offering diverse solutions for different industries. China began developing supercapacitors in the 1990s. In recent years, companies like China South Locomotive have made significant breakthroughs in structural design, material preparation, device fabrication, and system integration, achieving independent intellectual property rights. These advancements have helped overcome key technological bottlenecks that previously limited the development of supercapacitor technology. As a result, China has broken foreign technology blockades and become one of the few countries in the world capable of researching and developing high-capacity supercapacitors.

Macor Ceramic Structural Parts

Low-expansion and zero-expansion glass-ceramics are insensitive to temperature changes and can be used in applications where temperature changes but dimensional stability is required, such as housings for telescopes and lasers. The low expansion lithium-based glass ceramic is used for the fiber joint, and is more compatible with the Quartz Glass fiber in terms of thermal expansion coefficient and hardness than the zirconia material, and is easy to be precision processed and has good environmental stability.
