全球四大固态电池企业最新进展！

Core Viewpoint - Recent advancements in solid-state battery technology have been reported by several international companies, including Ampcera, Idemitsu Kosan, Ilika, and SK On, indicating a significant push towards commercialization and improved performance in this sector [1]. Group 1: Ampcera's Developments - Ampcera has announced the commercial launch of its new nano-sulfide solid electrolyte powder, which features uniform particle size and a chip size smaller than one micron, enhancing ionic conductivity and overall performance of solid-state batteries [2]. - The new electrolyte is expected to address technical bottlenecks in energy density and manufacturability, making it suitable for applications in electric vehicles, consumer electronics, aerospace, and defense [2]. - Ampcera's CEO stated that multiple battery developers and automotive manufacturers from the Americas, Europe, and Asia are already validating and ordering the product [2]. Group 2: Idemitsu Kosan's Strategy - Idemitsu Kosan plans to strengthen its solid-state battery materials business and is in discussions with various automotive companies for collaboration [3]. - The company aims to supply solid electrolytes for solid-state batteries by 2027, utilizing sulfur resources generated during petroleum refining [3]. - Idemitsu is also considering investments in large-scale solid electrolyte production facilities, with a decision expected before the end of the current fiscal year [3]. Group 3: Ilika's Testing Success - Ilika's latest vehicle solid-state battery prototype, P1 Goliath, has successfully passed tests conducted by OEMs and tier-one suppliers, confirming its performance meets specifications [4]. - The tests focused on the battery's charge and discharge capabilities, energy storage, and stability under repeated use, indicating good reproducibility and expected electrochemical characteristics [4]. Group 4: SK On's Research Innovations - SK On has published research on extending the lifespan of sulfide solid-state batteries, demonstrating that lithium metal can significantly enhance energy density but poses challenges in efficiency and longevity [5]. - By immersing lithium metal anodes in a special solution to form a protective layer, SK On has achieved over 300 charge-discharge cycles at room temperature, tripling the lifespan of existing metal batteries [5]. - Additionally, SK On's research on gel polymer electrolytes indicates that longer curing times improve battery performance, with a significant difference in discharge capacity based on curing duration [6].
