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

ZIBO, China, July 15, 2024 (GLOBE NEWSWIRE) -- Sunrise New Energy Co., Ltd. (“Sunrise New Energy”, the “Company”, “we” or “our”) (NASDAQ: EPOW), today announced the development of two innovative silicon-carbon anode products designed to meet the rapidly growing demands of electric vehicles and high-end 3C digital products. These products feature high energy density and high discharge rates. One product has a capacity of 1660mAh/g with an initial efficiency of 90%, while the other offers a capacity of 1800mAh/g with an initial efficiency exceeding 91%.

Sunrise New Energy's new silicon-carbon anode products fundamentally solve the high expansion problem of silicon-based materials during charge and discharge cycles, unlike the first-generation sand-milled silicon anodes with issues of low capacity, low initial efficiency, and poor cycle life, and the second-generation silicon oxide anodes with low initial efficiency. Silicon-based anode materials have a much higher theoretical specific capacity than graphite, leading to a significant increase in the penetration rate in high-end batteries.

Currently, Sunrise New Energy's silicon-carbon anode products boast high initial efficiency, high capacity, and excellent rate performance, with cycle life exceeding 1500 cycles. These products have already been applied in high-end 3C digital products and are in the development stage for use in power batteries. The new silicon-carbon anode materials are expected to be used in solid-state batteries, potentially achieving a single-charge range exceeding 1000 kilometers.

Additionally, Sunrise New Energy is collaborating with experts to build a 500-ton production line for high-performance, high-purity resin-based porous carbon materials, expected to be in operation by the end of the year. The Company has also developed automated equipment for continuous production, aimed at significantly reducing the high equipment investment and energy consumption per ton that competitors in silicon-carbon production typically encounter.

Sunrise New Energy's development pathway involves continuously introducing a high concentration of silane gas into a reactor loaded with three-dimensional porous carbon materials with fixed pore sizes and precisely designed surfaces. The silane rapidly adsorbs and decomposes into nano-silicon within the carbon material's pores. The three-dimensional framework of the porous carbon effectively suppresses the expansion of nano-silicon during charge-discharge cycles while providing fast pathways for lithium-ion and electron transport. Additionally, through a special dual-coating process, a double-layer "protective film" forms on the surface of the silicon-carbon anode particles, enhancing initial efficiency and cycle life.

"Solid-state batteries, rapidly penetrating the energy storage, consumer, and automotive sectors, are expected to drive increased demand for silicon-carbon anode materials. Sunrise New Energy's development of advanced high-energy density and high-rate silicon-carbon anode products is recognized as a leader in the next generation of lithium battery anode materials." stated Mr. Haiping Hu, CEO of Sunrise New Energy. "We remain committed to advancing battery technology, providing efficient and reliable battery materials. We have consistently focused on advancing cutting-edge technology development and industrialization."
