Core Viewpoint - The discussion around the mass production and large-scale application of solid-state batteries continues, with skepticism about the timeline for commercialization by 2030 and uncertainties regarding application scenarios, penetration rates, and pricing [2]. Group 1: Solid-State Battery Development - Sulfide solid-state batteries are currently the most popular route due to their high ionic conductivity, but they face challenges such as air sensitivity, solid-solid contact interface issues, and cost [2]. - The manufacturing process for solid-state batteries can be based on traditional lithium battery production lines, with modifications needed for key steps [4][5]. Group 2: Manufacturing Process - The production of traditional lithium batteries is divided into three stages: front-end (electrode manufacturing), mid-stage (cell assembly), and back-end (packaging) [4]. - The front-end involves the manufacturing of positive and negative electrode sheets using a wet process, which is mature but has drawbacks such as solvent use and energy consumption [8]. - In the solid-state era, the wet process is problematic due to the sensitivity of sulfide solid electrolytes to moisture and oxygen, leading to a shift towards dry processing methods [8][9]. Group 3: Electrode Preparation - The industry is currently exploring both dry and wet processes, with a more aggressive approach towards dry methods, as exemplified by companies like CATL and Toyota [9]. - Dry processing eliminates solvent use and energy consumption, making it more environmentally friendly and compatible with solid electrolytes, but it is still in the validation and improvement stage [8][9]. Group 4: Cell Assembly Techniques - Traditional lithium batteries use either winding or stacking methods for cell assembly, but solid-state batteries primarily rely on stacking due to the non-flowing nature of solid electrolytes [11][12]. - The absence of a separator in solid-state batteries allows the solid electrolyte to serve both as a separator and an ionic conductor, which changes the assembly process significantly [12]. Group 5: Solid-Solid Interface Densification - The interface between the solid electrolyte and electrodes is critical in solid-state batteries, as any gaps or roughness can lead to high resistance and affect performance [15]. - Densification methods for the solid-solid interface include uniaxial and biaxial pressing, with the latter providing more uniform pressure distribution [16][18]. Group 6: Industry Trends and Future Outlook - Companies like CATL prioritize mass production capabilities, while others like Toyota focus on multi-layer coating processes [18]. - The transition from material breakthroughs to engineering implementation is a key phase for the industry, with many challenges shifting from scientific to manufacturing issues [20].
