Advancements in Quantum Technology
Quantum communication, a communication technology that uses quantum states as information carriers, with quantum key distribution (QKD) as a typical application, has greatly simplified the cumbersome process of key distribution and reduced risks, and improved efficiency by generating shared keys online based on the principles of quantum mechanics.
However, in actual quantum key distribution, quantum states are subject to interference from environmental factors such as temperature and vibration as the link changes, limiting the practical application of QKD. In an interview, Tang Shibiao, Vice President and R&D Director of Science and Technology Group Quantum Technology Co., Ltd., mentioned the company’s invention patent “Quantum Key Distribution System and Method for Complex Links,” which provides an efficient feedback compensation solution for this issue, significantly improving the efficiency of QKD system link tracking compensation. Such innovative solutions not only won them the 24th China Patent Silver Award but also instill confidence in the future development of quantum communication.
Ethylene Glycol Synthesis Technology
The use of clean energy is one of the effective ways to achieve the “dual carbon” goal. The invention patent “A Process for Synthesis Gas Production by Supplementing Carbon from Coke Oven Gas Conversion to Ethylene Glycol” by Donghua Engineering Technology Co., Ltd. uses coke oven gas as raw material to convert it into synthesis gas through one of the new routes of coal coking technology and then synthesizes ethylene glycol. This innovative technology won the Silver Award in the 24th China Patent Evaluation.
Yu Jun, a master of engineering survey and design in Anhui Province and chief engineer of Donghua Technology, introduced that the patent creatively used methane and carbon dioxide reforming technology, which can reduce the process steam consumption of conversion units by 20% to 30% compared to similar technologies and reduce fuel consumption by 25% to 35%. At the same time, this technology can consume carbon dioxide in the process system, absorb external carbon sources, and achieve negative carbon effects. This innovative patent not only achieves the resource utilization of carbon dioxide and significantly reduces energy consumption but also has significant economic and social benefits. He also pointed out that after the successful development of this technology, it has been recognized by many coking enterprises and achieved the expected results in industrial applications.
“Currently, the company’s synthesis gas to ethylene glycol technology has entered the refinement stage, and the raw material structure can achieve a variety of choices from coal to natural gas and other hydrocarbon industrial exhaust gases. Through process optimization, advanced energy-saving and consumption-reducing processes and equipment, we have realized the large-scale production of ethylene glycol units and improved the industry’s energy efficiency level.” Yu Jun said. This series of innovations fills me with confidence in the future of clean energy technology, especially in achieving the “dual carbon” goal, where technological advancements are creating a cleaner, more sustainable future for us.
Koda New Materials Patent Innovation
In the field of energy conservation and environmental protection, Anhui Koda New Materials Co., Ltd. (Koda New Materials) has successfully addressed the challenges of new energy vehicles. Their core patent, “Method for preparing artificial graphite negative electrode material for lithium-ion batteries,” won the 10th Anhui Province Patent Silver Award.
The uniqueness of this patent lies in its innovative combination of traditional carbon microsphere technology and dynamic artificial graphite technology, forming a completely new process for preparing artificial graphite. It successfully breaks through performance bottlenecks. Yang Li, General Manager of Koda New Materials, excitedly told reporters that this “black technology” not only extends the range of new energy vehicle mileage but also accelerates charging speed.
Yang Li revealed that the novel artificial graphite negative electrode material of this patent has characteristics such as high-temperature resistance, fast charging, high energy, and long life. What’s even more inspiring is that this technological breakthrough can reduce production costs for enterprises by 15%, and every ten thousand tons of patented products can achieve the reuse of 300 tons of solid waste, which is both environmentally friendly and cost-saving.
“Intellectual property rights are crucial for enterprise development, and we have always attached great importance to them.” Yang Li proudly introduced that in the past three years, Koda New Materials has earned 700 million yuan in sales revenue through patents, obtained an additional income of 7 million yuan from patent licensing, and even obtained 20 million yuan in patent pledge financing. Currently, they have accumulated a total of 54 Chinese patents, bringing significant technological breakthroughs to the negative electrode material industry for new energy vehicles in Anhui Province.
These series of patent achievements not only demonstrate the company’s own technological strength but also provide a strong boost to the entire new energy vehicle industry. For Anhui Province, this is not only a technological breakthrough but also an industrial leap forward. In the future, Anhui will aim to become a high-level innovative province, increase support for original innovation, deepen patent navigation services, and make intellectual property rights a “catalyst” for promoting innovation and an “accelerator” for economic development. The patent innovation of Koda New Materials is a bright color in this overall framework.
