聚烯烃是全球用量最大的合成树脂，而茂金属催化剂决定了其中最高端的那一部分能走多远。据Fortune Business Insights的预测，全球茂金属聚烯烃市场规模将从2025年的216.8亿美元增长到2034年的575.1亿美元，年均复合增速约11.45%。仅茂金属聚乙烯一个品类，全球消费规模在2022年就已超过65亿美元，包装薄膜是其最大的应用领域，太阳能等新兴领域的需求也在快速扩大。与此同时，汽车轻量化、医疗、光学、风电和航空航天等行业对高性能、可定制聚合物的需求持续走高，使“高端化、差异化”成为全球聚烯烃产业最清晰的发展方向。这条产业链上最关键的一环，恰恰是催化剂。与传统Ziegler-Natta催化剂的多活性中心不同，茂金属催化剂是单活性中心催化剂，分子量分布、共聚单体插入比例和立构规整度都可以通过分子结构来精确设计，这正是POE（聚烯烃弹性体）等高端产品所必需的。研究机构对POE的分析指出，其技术壁垒集中在茂金属催化剂、高碳α-烯烃和溶液聚合工艺三处，目前商业化POE主要采用桥联二茂催化剂和限制几何构型（CGC）催化剂，并需要甲基铝氧烷（MAO）等助催化剂配合。也正因为壁垒高，全球POE的供应长期集中在陶氏、埃克森美孚、三井化学、LG、SK-SABIC、北欧化工等少数企业手中，合计产能约168万吨/年。换句话说，谁掌握了配体、主催化剂和助剂的合成能力，谁就握住了高端聚烯烃的“芯”。而Watson正是要在这一关键环节上打破现有格局。公司深耕茂金属催化剂材料，基于ChemWhat全球品牌授权，已构建起覆盖核心茂金属化合物、助剂和载体三大类的完整产品体系，目前开发出14种产品。在非桥联结构方面，有双（1-正丁基环戊二烯基）二氯化锆（M1）、双（1-正丁基-3-甲基环戊二烯基）二氯化锆（M2）、双（茚基）二氯化锆（M3），以及茚基与取代环戊二烯基组合的不对称结构M4和M5。在桥联和限制几何构型方面，产品包括二苯基亚甲基桥联的锆、铪体系（M6、M7）、用于乙烯与高碳α-烯烃共聚的CGC钛催化剂（M8）、外消旋乙基桥联与二甲基硅桥联的双茚基锆及其四氢茚基衍生物（M9至M12），以及适合高立构选择性聚合的M13。助剂方面，Watson提供10%甲苯溶液形式的甲基铝氧烷（MAO），并掌握烷基铝和有机硼助剂的合成技术。上述茂金属化合物纯度均大于98%，为下游催化剂的制备...

1. Why Batteries Seem to “Wear Out” Why does a phone feel less durable after two or three years? Why does an electric vehicle’s range slowly shrink? Behind both lies a cause that few people know about: the active lithium that “carries” a battery’s charge is gradually consumed. A lithium-ion battery works by shuttling lithium ions back and forth between the positive and negative electrodes. These shuttling ions are called active lithium, and almost all of it is initially stored in the cathode material. Every bit of active lithium lost means a bit less battery capacity. During the first charge, a protective film, called the solid electrolyte interphase (SEI), forms on the surface of the anode and permanently “swallows” part of the lithium supplied by the cathode. It is like opening a new account and being charged a fee before you have used it, and a little more lithium continues to be lost with every subsequent cycle. 2. Prelithiation: Paying the “Fee” in Advance Prel...

Lithium squarate (Li₂C₄O₄) is a new cathode prelithiation additive that releases active lithium during the first charge to offset losses. It leaves only about 19% residue by weight, is a neutral salt that does not react with water or air, and can be added directly during cathode slurry mixing with no changes to the production line. Under ChemWhat brand authorization, Watson is producing high-purity lithium squarate (Li₂C₄O₄) raw material in volume for partners worldwide, and is extending the same approach to develop sodium squarate (Na₂C₄O₄) for sodium batteries.

Watson在ChemWhat品牌授权下，目前正为全球合作伙伴大批量生产高纯方酸锂原料，为下游企业开发包碳等改性产品提供稳定的品质基础。与此同时，Watson也在沿着同样的思路开发方酸钠，面向钠电池。钠电池在首次充电时同样会损失一部分活性钠，补钠的原理与补锂相通。从锂到钠，Watson希望把在方酸盐材料上积累的合成与品质控制经验延伸到更多电池体系，为新一代储能技术提供可靠的原料支持。 https://www.youtube.com/watch?v=FqEB6EnBM7w

From late 2025 to early 2026, surging silver prices placed unprecedented cost pressure on the photovoltaic and electronics manufacturing industries, bringing silver-coated copper powders back into the spotlight as a composite material that balances conductivity and cost efficiency. For heterojunction (HJT) solar cells, where silver paste accounts for a significant share of production costs, reducing silver consumption has become a key factor in competitiveness. In conductive adhesives, inks, electromagnetic shielding, and electronic components, the need to control precious-metal costs while maintaining electrical performance and long-term reliability is also driving the development of alternative materials. The value of silver-coated copper powders lie not simply in replacing silver with copper, but in engineering a material structure that balances conductivity, oxidation resistance, and cost. Also known as silver-plated copper powders, these materials feature a core-shell structure in...
