The Graphene Industry Fund, with a total scale of 20 billion yuan, was officially launched in Nanjing. The fund focuses on the integration of capital and industry to build a comprehensive graphene ecosystem, aiming to address challenges in the development of the graphene industry and promote innovation and growth. By supporting strategic investments, it seeks to drive long-term industrial progress rather than just short-term speculation.
Li Yichun, Secretary of the China Strategic Alliance for Graphene Industry Technology Innovation, noted that only a handful of Chinese companies—no more than five—have truly made graphene a core part of their business, investing hundreds of millions of yuan into its development. He criticized the presence of many companies that are "dry, fake, or hype," emphasizing the need for real investment and practical application rather than mere conceptual炒作.
According to Li, the difference between investment in the industry and investment in projects is crucial. The graphene market remains mixed, with some companies engaging in speculative behavior by leveraging the concept of graphene without real substance. He stressed that the key challenge in advancing graphene’s industrialization lies in its practical applications, not just technological development.
Currently, the layout of graphene-related companies across China is uneven. Graphene, a two-dimensional material composed of a single layer of carbon atoms, is known for its exceptional strength, electrical conductivity, thermal properties, and transparency. After years of research and development, the path toward large-scale production has become clearer, with significant progress observed in recent years.
Several listed companies have actively entered the graphene sector through acquisitions, equity participation, and other strategies. For example, Dongxu Optoelectronics, Rongqi Group, Del Future, and others have made notable moves to integrate graphene into their product lines. Dongxu Optoelectronics, in particular, released the world's first graphene-based lithium-ion battery in 2016 and has since built a closed-loop industrial chain from graphene to new energy vehicles.
In October 2023, Dongxu Optoelectronics announced a strategic partnership with the University of New South Wales to develop high-performance graphene products such as bucky paper, super desiccants, and supercapacitors. The company's deputy general manager, Wang Chenghui, highlighted that they have established two key application ecosystems: one centered around graphene batteries and new energy vehicles, and another focused on smart cities using graphene heat dissipation and LED lighting solutions.
Li Yichun praised Dongxu Optoelectronics for its leadership in graphene development, noting that its technology has high content and strong barriers to entry. However, he also warned that many companies still engage in speculative practices, creating an unstable market environment.
Jie Xiaolan, a researcher at Puhua Research, pointed out that while the graphene industry chain in China is beginning to take shape, with coverage from raw materials to downstream applications, the number of leading enterprises remains small. This limits the overall development of the ecosystem. Despite this, China has shown strong potential, with the world’s largest graphite reserves, the highest number of graphene patents, and a growing number of companies entering the field.
With continued policy support and the formation of innovation alliances, the graphene industry chain is expected to become more complete by 2018. Analysts predict that the graphene industry could reach a trillion-yuan scale by 2020. Looking further ahead, Xiao Jinsong from the Institute of Industry and Information Technology believes that the industry will mature between 2021 and 2035, with advanced graphene-based devices like terahertz detectors and biosensors becoming commercially viable.
However, challenges remain. The industrial chain is still weak, lacking a fully developed system. Upstream production and downstream applications are not well integrated, and many companies struggle to find sustainable business models due to limited demand. As Li Yichun explained, without real applications, mass production becomes unprofitable, and the cost of producing large quantities is too high.
Jie Xiaolan added that while China has abundant graphite resources, there are still technical hurdles in midstream production, and downstream applications remain costly and inefficient. To overcome these issues, she called for stronger policy guidance, better coordination between research, production, and application, and collaborative efforts among leading companies, universities, and SMEs to tackle key technological bottlenecks.
Ultimately, the future of the graphene industry depends on continuous innovation, strong application pull, and a balanced supply-demand relationship. With the right strategies and sustained investment, China is well-positioned to lead the global graphene revolution.
Fiber Optic Adapter
Fiber optic adapter are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. People sometimes also name them to be mating sleeves and hybrid adaptors, mating sleeves means this fiber optic adapter is used to connect the same type fiber optic connectors, while hybrid adaptors are the fiber optic adaptor types used to connect different kinds of fiber optic connectors. YLTelecom`s fiber adapter provide reliable solution for fiber connections, single mode fiber optic adaptors and multimode fiber optic adaptors available on request. We adopt high quality raw materials and make these fiber optic adapters strictly according to international standard, this makes our fiber optic adaptors with high performance.
Fiber Optic Adapters FC, SC, ST, LC, MT-RJ, MU, E2000, FC/APC, SC/APC, LC/APC, E2000/APC, Simplex, Duplex, Quad, mating sleeves, hybrid fiber optic adapters, Single mode fiber optic adapters, multimode fiber optic adapters are all available.
Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad).
Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables. This can cause misalignment of the small singlemode fibers and loss of signal strength (attenuation).
When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125). A mismatch here will cause attenuation in one direction (where the larger fiber is transmitting light into the smaller fiber).
Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called "hybrid", accept different types of connectors (ST to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.
