In the context of the rapid development of the new energy storage and power battery industries, high safety, long cycle, high energy density, low carbon and environmental protection have become the core development trends of the industry. Traditional energy storage supporting materials such as polyolefin and glass fiber are limited by their physical structure and chemical properties. They generally have problems such as poor wettability, insufficient high temperature resistance, weak mechanical stability, and poor environmental protection. They are difficult to meet the iterative needs of high-end lithium batteries, large-scale energy storage, and solid-state batteries. As a new type of natural biomass nanofunctional material, nanocellulose has multiple advantages such as high strength, high porosity, super electrophilicity, temperature resistance and stability, and biodegradability due to its unique three-dimensional nanonetwork structure. It has become a core new material in the current field of new energy storage to break through material bottlenecks and achieve product quality and cost reduction. Nanocellulose is mainly made of bamboo pulp, agricultural and forestry straw and other renewable biomass as raw materials. The whole process is green preparation, low carbon and low consumption, no harmful residues, and can achieve environmental protection and controllability throughout the life cycle. compared to traditional

In the field of outdoor building materials, traditional wood is easy to rot and crack, ordinary plastic plates have poor weather resistance, and metal plates are easy to rust and consume high energy. The industry is in urgent need of new materials that are environmentally friendly, durable, and high-strength. Nanocellulose outdoor panels (NCT panels for short) use nanocellulose extracted from plant fibers as the core raw material. With the advantages of nanoscale structure and composite modification technology, they are perfectly adapted to complex outdoor working conditions and have become the first choice for upgrading the outdoor panel market, promoting the transformation of the building materials industry into a low-carbon, long-term, and safe direction. 1. Nanocellulose: Nanocellulose, the core hard-core material of outdoor boards, is a nanoscale fiber material extracted from natural plant fibers such as wood, straw, and bamboo through mechanical dissociation, enzymatic hydrolysis, and other processes. It has a diameter of only 1-100 nanometers, but has core properties that far exceed those of traditional materials. Ultra-high strength: The tensile strength of nanocellulose is more than 5 times that of steel, and the Young's modulus is close to that of carbon fiber, providing stability for outdoor boards.
