干法电极成套装备迎“新进展”

Core Viewpoint - The article emphasizes the acceleration of dry electrode equipment towards industrialization, highlighting its potential to overcome existing challenges in solid-state battery production [1]. Industry Overview - The dual drivers of global carbon neutrality goals and the explosive growth of the electric vehicle industry position solid-state batteries as the "ultimate solution" for next-generation power batteries due to their high energy density and safety [2]. - However, the commercialization of solid-state batteries is hindered by complex processes, high costs, and difficulties in mass production [3]. Technical Challenges - Current solid-state battery preparation processes primarily rely on wet slurry coating, which has significant drawbacks, particularly in the application of solid electrolytes [4]. - The traditional wet process involves substantial solvent use, leading to complicated production workflows and high energy consumption, while also posing safety risks due to poor compatibility with solid electrolyte materials [4]. Dry Electrode Technology - Dry electrode technology eliminates the need for solvents, utilizing physical mixing, fiberization, and calendering to produce electrode films, significantly reducing production steps and avoiding solvent residue safety issues [4]. - This technology is adaptable to various solid electrolyte materials, particularly polymers and sulfides, and could revolutionize the manufacturing logic of solid-state batteries if equipment and process bottlenecks are overcome [4]. Company Innovations - Guan Hong Intelligent has made breakthrough innovations in the field of dry electrode complete intelligent equipment, which includes a range of devices such as powder mixers, high-speed dispersers, kneaders, continuous granulators, and double-sided dry coating equipment [5]. - The materials produced using Guan Hong's dry electrode equipment exhibit a fiber diameter of less than 50nm, strong compatibility with various battery types, and a film thickness ranging from 15-150μm, with a strength of 1-4N and first pass yield exceeding 91% [5]. Process Innovations - The company has developed a special paddle design for its mixers that improves mixing efficiency by over 50% and ensures powder uniformity at an industry-leading level [6]. - Guan Hong's fiberization process includes a high-mixing machine for batch processing and a kneader for continuous processing, achieving fiber diameters smaller than 50nm and enhancing electrode strength significantly [8]. - The granulation and calendering processes utilize precision mold designs and AI algorithms for closed-loop control, improving film thickness and material flow [9]. Market Positioning - Guan Hong's equipment has been validated by clients, with mass production line delivery cycles reduced to under four months [10]. - The acquisition by Huaya Intelligent provides Guan Hong with substantial resources for product, technology, and market expansion, enabling rapid penetration into overseas markets [12][14]. - The strategic focus includes continuous innovation in intelligent logistics systems and optimization of dry electrode equipment for new application areas [14].
