Core Viewpoint - All-solid-state batteries are emerging as a significant driving force for the future development of the new energy vehicle industry, with the first large-capacity production line in China already established and undergoing small-scale testing [1]. Group 1: Advantages of All-Solid-State Batteries - The primary advantage of all-solid-state batteries over traditional lithium-ion batteries is the absence of any liquid, utilizing solid materials instead, which enhances safety and extends the range of future electric vehicles [1]. - The "no liquid" battery advantage stems from two key innovations in the production line, where the traditional three-step process of slurry, coating, and rolling has been streamlined into a single dry process, reducing energy consumption and improving efficiency [3]. Group 2: Technical Breakthroughs - The energy density of the newly developed all-solid-state batteries has nearly doubled compared to existing batteries, allowing vehicles to achieve a range of over 1000 kilometers, with plans for small-scale vehicle testing by 2026 and gradual mass production from 2027 to 2030 [11]. - A significant breakthrough in the all-solid-state battery technology is the replacement of traditional liquid electrolytes with self-developed solid electrolyte materials, which greatly enhance the product's heat resistance and safety, capable of withstanding temperatures above 300-400 degrees Celsius compared to the 100-200 degrees Celsius limit of liquid electrolytes [7]. Group 3: Production Capacity and Future Plans - The establishment of the first large-capacity all-solid-state battery production line in China positions the industry to achieve batch production of automotive-grade all-solid-state batteries with a capacity of over 60 ampere-hours [9]. - The current maximum capacity of the new battery technology has improved from less than 5 milliamp-hours per square centimeter to 7.7 milliamp-hours per square centimeter, resulting in higher energy density and longer vehicle range [5].
