（速新闻记者 孙安）8月18日上午，在位于宿豫区的宿迁澳中玻璃股份有限公司生产车间内，工人正加 紧生产一批高档玻璃移门。作为一家拥有7项发明专利的国家高新技术企业，该公司目前95%的产品远 销海外。然而，就是这样一家技术实力突出的企业，此前却因融资渠道有限，发展一度受阻。 "我们曾多次尝试利用专利进行融资，但因为找不到合适途径，始终未能成功。"该公司董事长何志权坦 言。 转机出现在今年初。宿豫区相关部门在"企业大走访"活动中主动对接企业，全程指导企业通过知识产权 质押获得融资。"预计公司新增1000万元流动资金贷款，这对公司来说，无疑是雪中送炭。"何志权说。 宿豫区市场监督管理局知识产权科科长蔡同春介绍，他们在走访调研中发现，辖区内不少科技型中小企 业存在"知识产权闲置"问题。 "企业大量专利等轻资产未能有效转化运用。我们通过精准服务，努力帮助企业破解'融资难'。"蔡同春 说。 目前，宿豫区有效发明专利总量达1107件，其中高价值专利705件，占比达63.68%。"这无疑是一座尚待 深挖的富矿。"宿豫区有关部门负责人表示，将继续强化与金融机构、担保公司及专业服务机构的协 作，通过举办政银企对接会、开展"送政策 ...

Core Viewpoint - The rapid development of new energy storage technologies in China is evident, with a clear trend towards "long-duration" storage solutions, particularly in flow batteries and compressed air energy storage [2][3][4] Policy Support - National policies are increasingly supportive of large-scale and medium-to-long duration energy storage projects, with multiple initiatives aimed at enhancing the commercial viability of long-duration storage [3][5][7] - Local governments are also implementing subsidy policies to improve the economic competitiveness of new energy storage projects, with various regions offering significant financial incentives [7][8] Market Growth - The installed capacity of new energy storage projects in China surpassed 137.9 GW by the end of 2024, with new energy storage alone reaching 78.3 GW, marking a year-on-year growth of 126.5% [9][11] - The proportion of long-duration storage projects (4 hours and above) has increased to 15.4% of the total installed capacity, reflecting a growing focus on long-duration energy storage solutions [11][13] Technology Development - Flow battery installations have seen rapid growth, with a total capacity exceeding 1 GWh in the first half of 2025, representing a year-on-year increase of approximately 272% [14][15] - The flow battery market is diversifying, with all-vanadium flow batteries dominating but other technologies like zinc-iron and iron-chromium also making progress [15][17] - Compressed air energy storage projects are gaining traction, with 14 projects initiated in early 2025, totaling 4.1 GW/18.7 GWh, a 33.3% increase from the previous year [24][26] Project Scale - The trend towards larger-scale projects is evident, with the number of flow battery projects exceeding 100 MW increasing from 1 in 2023 to 4 in 2024, and 14 more in development [22][24] - Significant breakthroughs in large-capacity compressed air projects have been achieved, including the world's first 300 MW compressed air storage facility [26][29] Emerging Technologies - The potential of compressed carbon dioxide storage technology is beginning to emerge, with two projects under construction, totaling 200 MW/1400 MWh, indicating a growing interest in this area [29][30]

Core Insights - A new interface crosslinking strategy has been developed for ion-selective membranes used in flow batteries, resulting in a high stability ultra-thin polymer membrane with a thickness of only 3 micrometers, which enhances the working current density of all-vanadium flow batteries to 300 milliamps per square centimeter [1][2] Group 1: Research Findings - The polymer ion-selective membrane is favored in the market due to its low cost and ease of large-scale production, but traditional methods often lead to irregular pore structures that hinder precise separation of active materials and charge carriers [1] - The new membrane features a pore size distribution between 1.8 to 5.4 angstroms, similar to inorganic nanoporous materials, allowing for precise screening of active materials and rapid conduction of charge carriers [2] - The robust covalent crosslinking network within the separation layer enhances the mechanical stability of the membrane, demonstrating good mechanical strength even at a reduced thickness of 3 micrometers, outperforming commercial Nafion 212 membranes in tensile strength and hardness [1] Group 2: Application and Performance - The membrane was tested in an all-vanadium flow cell, achieving an energy efficiency exceeding 80% at a high current density of 300 milliamps per square centimeter [2] - The ultra-thin membrane also shows excellent performance in alkaline zinc-iron flow batteries and aqueous organic flow batteries under high current densities [2] - The universality of the interface crosslinking strategy was further validated by varying the type of crosslinking agent used [2]
