Market Review - The Shanghai Composite Index experienced narrow fluctuations, while the ChiNext Index saw reduced trading volume. Silver concept stocks surged, with companies like Hunan Silver and Silver Nonferrous hitting the daily limit. Computing power concept stocks continued to rebound, with Huamai Technology and Nanling Technology also reaching the limit. Agricultural chemical stocks remained strong, with Su Li Co., Mei Bang Co., and Changqing Co. hitting the daily limit. In contrast, stablecoin concept stocks faced adjustments, with Xiongdi Technology dropping over 10% [1]. Silver Sector - The silver sector saw significant gains, with stocks like Zhongrun Resources and Hunan Silver hitting the daily limit. Comex July silver futures rose by 4% to $36.03 per ounce, reaching a peak of $36.27, the highest level since February 2012. Over the past 12 months, gold has increased by 42%, while silver's rise was approximately 15%, indicating a lag [4][5]. - The gold-silver ratio, which measures the price relationship between gold and silver, suggests that silver may be undervalued when the ratio approaches its upper historical range [5]. - From late May, silver's upward momentum has been building, with expectations that the gold-silver ratio may revert to pre-tariff levels. The demand for industrial silver is projected to rise due to the growth in photovoltaic and electric vehicle sectors, with silver usage in hybrid and electric vehicles increasing by 21% and 71%, respectively [6]. Agricultural Chemicals - The computing power sector remained active, with Su Li Co. achieving two consecutive daily limits, and other companies like Mei Bang Co. and Changqing Co. also hitting the limit. A recent explosion at a chemical plant in Shandong related to the production of chlorantraniliprole intermediates has raised concerns [7][9]. - The explosion is expected to lead to price increases for intermediates like K-amine, and stricter regulations on nitration processes in the agricultural chemical industry. The industry is gradually returning to rationality, with high-priced inventory being depleted and procurement demand recovering, although supply-side pressures persist [9]. Solid-State Batteries - The solid-state battery sector showed strong performance, with companies like Dexin Technology and Jinying Co. hitting the daily limit. The market for solid-state batteries is projected to open up by 2030, with significant demand for solid electrolytes and lithium sulfide, indicating a market space exceeding 210 billion yuan [10][12]. - The development of solid-state batteries is expected to drive significant demand for lithium sulfide, with upstream production capacity facing notable shortages, which could hinder cost reductions [12].

半固态电池是全固态电池的过渡路线，但却是两个完全不同的概念。 近日，中国汽车工程学会正式发布《全固态电池判定方法》团体标准，首次明确了全固态电池的定义， 解决了行业界定模糊、测试方法缺失等问题，为技术升级和产业化应用奠定基础。 5月21日，据央视新闻报道，中国科学院金属研究所沈阳材料科学国家研究中心王春阳研究员联合国际 团队近期取得重要突破，利用三维电子绝缘且机械弹性的聚合物网络，发展了无机/有机复合固态电解 质，有效抑制了固态电解质内部的锂金属析出、互连及其诱发的短路失效，显著提升了其电化学稳定 性。该研究成果5月20日发表在《美国化学会会刊》。 而电池产业链相关企业也相继发布半固态/固态电池新品。比如国轩高科近日官宣建成0.2GWh全固态电 池中试线，并发布了包括G垣准固态电池在内的6项新产品；宁德时代近期在投资者调研活动中表示， 公司在全固态电池上持续坚定投入，2027年有望实现小批量生产；当升科技近日在互动平台表示，公司 与清陶能源已建立紧密战略合作关系，2024年出货量同比大幅增加，未来将共同推进固态电池技术研发 及产业化应用进程。 不过，全固态电池产业化仍需解决技术、工艺和成本的问题。在成本上，以 ...

Group 1 - The China Automotive Engineering Society released the "Full Solid-State Battery Determination Method" standard, clarifying the definition of solid-state batteries and addressing industry ambiguities and testing method deficiencies [1] - Solid-state batteries offer advantages such as higher safety, energy density, cycle life, mechanical strength, wider temperature adaptability, and material selection, with high safety and capacity being core benefits [1] - Beneficiary companies in the materials sector include CATL, BYD, Yiwei Lithium Energy, Penghui Energy, Tiannai Technology, Xiamen Tungsten, and others [1] Group 2 - The industrialization of solid-state batteries is accelerating, with a focus on the sulfide route in the materials sector and key incremental developments in the equipment sector related to "dry," "press," and "stack" processes [2] - In the front-end segment, dry electrode equipment and solid electrolyte dry film forming equipment are expected to gradually replace traditional wet equipment [2] - The solid-state battery production process requires significantly higher pressure during formation, leading to increased demand for high-pressure formation equipment [2]
