Sunrise New Energy Launches High-Energy Density and High-Rate Silicon-Carbon Anode Products for Solid-State Batteries

Core Viewpoint - Sunrise New Energy Co., Ltd. has developed two innovative silicon-carbon anode products aimed at meeting the increasing demands of electric vehicles and high-end 3C digital products, featuring high energy density and discharge rates [1][2]. Product Development - The new silicon-carbon anode products address the high expansion issues of silicon-based materials during charge and discharge cycles, improving upon previous generations of silicon anodes that suffered from low capacity and efficiency [2]. - The products have capacities of 1660mAh/g and 1800mAh/g, with initial efficiencies of 90% and over 91% respectively, and a cycle life exceeding 1500 cycles [1][3]. Market Application - These silicon-carbon anode materials are already being utilized in high-end 3C digital products and are in development for power batteries, with potential applications in solid-state batteries that could achieve a single-charge range exceeding 1000 kilometers [3][5]. Production Capacity - Sunrise New Energy is establishing a 500-ton production line for high-performance, high-purity resin-based porous carbon materials, expected to be operational by the end of the year [3]. - The company has developed automated equipment for continuous production, aimed at reducing equipment investment and energy consumption compared to competitors [3]. Technological Innovation - The production process involves introducing a high concentration of silane gas into a reactor with three-dimensional porous carbon materials, which helps suppress the expansion of nano-silicon during charge-discharge cycles [4]. - A dual-coating process creates a protective film on the silicon-carbon anode particles, enhancing initial efficiency and cycle life [4]. Industry Position - The demand for silicon-carbon anode materials is expected to rise with the growth of solid-state batteries in energy storage, consumer, and automotive sectors, positioning Sunrise New Energy as a leader in next-generation lithium battery anode materials [5].
