Group 1 - The 17th Shenzhen International Battery Technology Exchange Conference/Exhibition (CIBF2025) was held, where the director of the Central Research Institute of Better Energy, Li Zikun, discussed the application of solid-state electrolyte materials in semi-solid battery systems, indicating that clear positive feedback has not yet been observed in power batteries [2] - The industrialization of semi-solid battery systems follows a path of "first digital systems, then power batteries," while the more complex all-solid-state battery systems are expected to have clear industrialization milestones only after 2027 [2] - Cost issues remain a significant challenge for all-solid-state systems, with initial semi-solid systems being prioritized for use despite higher costs, until competitive advantages in cost are achieved [2] Group 2 - Better Energy has released a comprehensive solution for solid-state battery materials, including the BETAN FLEX semi-solid and GUARD all-solid-state series, which covers both current semi-solid battery applications and anticipated all-solid-state systems post-2027 [3] - The company has been advancing the intelligence of its R&D platform, actively integrating AI for science, including big data computing, simulation, modeling, and material screening into its R&D processes [3] - Since 2017, Better Energy has been focusing on key materials for solid-state batteries, with its solid electrolyte product being the first commercially available in the industry, and its clients include major companies like CATL, BYD, and Samsung SDI [3]

Core Viewpoint - The solid-state battery industry faces significant challenges in commercialization, including immature supply chains, higher costs compared to lithium batteries, and reliance on imported key materials [1][5][6] Group 1: Industry Developments - Recent events have catalyzed interest in solid-state batteries, with companies like Better Ray (贝特瑞) launching new materials and Guoxuan High-Tech (国轩高科) expected to unveil new products at an upcoming conference [1][2] - Institutional investors have been actively visiting companies in the solid-state battery supply chain, with many firms projecting 2027 as the timeline for mass production [1][3] Group 2: Production and Technology - Battery manufacturers generally anticipate 2027 for the scale-up of solid-state battery production, with companies like CATL (宁德时代) and Guoxuan High-Tech aiming for small batch production and testing by that year [3][4] - The solid-state battery production cost is projected to decrease significantly but will still be five times higher than conventional lithium-ion batteries, with S&P forecasting a cost of USD 500/kWh by 2025 [5][6] Group 3: Market Dynamics - The solid-state battery sector is currently divided into two camps: those pursuing semi-solid-state solutions aiming for mass production within two years, and those committed to all-solid-state technologies targeting the post-2027 market [5][6] - The materials segment is still in a phase of multiple technological approaches, with no single method demonstrating a clear cost or efficiency advantage [5][6] Group 4: Future Outlook - Analysts predict that by 2025, there will be batch deliveries of semi-solid-state batteries and accelerated development of all-solid-state solutions, with the automotive industry entering a competitive phase [7]
