Core Viewpoint - The article discusses the current state and future prospects of semi-solid and solid-state batteries, highlighting their production status, market positioning, and technological challenges. Group 1: Production Status - Semi-solid batteries have begun gradual mass production, applied in fields such as new energy vehicles and consumer batteries [1] - Solid-state batteries are still in the development phase, with leading companies constructing production lines of hundreds of megawatt-hours [1] - By 2027, small batch production is expected to be priced between 0.9 to 1.1 yuan, with further reductions anticipated by 2028 and 2030 [8][13] Group 2: Market Positioning - Semi-solid batteries may serve as a transitional product before solid-state batteries mature, but their market share is expected to remain low in the next 5 to 8 years [2][3] - The relationship between semi-solid batteries and traditional ternary lithium batteries will involve coexistence, with semi-solid batteries not significantly impacting market structure [3] Group 3: Technological Challenges - The production cost of sulfide solid electrolyte membranes is currently very high, around 1 million yuan per ton, which limits large-scale application [4] - Key technological bottlenecks include dry electrode technology and achieving stable, high conductivity solid electrolyte membranes [4][5] - The core technical challenge for sulfide materials is achieving the necessary density for stable conductivity and ideal membrane structure [5] Group 4: Cost Projections - By 2026, the cost of lithium sulfide is expected to drop to between 600,000 to 1 million yuan, with further reductions anticipated by 2028 and 2030 [7] - The cost of semi-solid batteries is currently around 0.55 yuan, which is higher than that of lithium iron phosphate batteries, priced below 0.3 yuan [11] Group 5: Equipment and Collaboration - The battery manufacturing sector is undergoing adjustments, with some manufacturers providing complete line equipment focused on dry electrode technology [9][10] - Major battery companies are collaborating with equipment manufacturers for technical support, particularly in the backend processes [10]
