Under the dual-carbon strategy, green renewable materials have become the core direction of industrial upgrading. Nanocellulose, as a new nanomaterial extracted from natural biomass, has become the key to solving pain points and upgrading the paper industry with its advantages such as environmental protection, high strength, and degradability. Nanjing Tianlu Nanotechnology focuses on the research and development and production of nanocellulose, empowering the high-quality development of the paper industry. Nanocellulose: Definition, Classification and Core Advantages Nanocellulose is a fibrous material that deconstructs natural cellulose to the nanometer scale (1-100 nanometers in diameter) through mechanical, chemical and other processes. The raw material is derived from natural biomass such as wood and straw. It is rich in reserves, green and degradable. It is mainly divided into three categories and is suitable for different application scenarios: • Cellulose Nanocrystal (CNC): High crystallinity, strong rigidity, suitable for high-strength coatings and precision composite materials; • Cellulose nanofiber (CNF): has excellent flexibility and good film-forming properties, and is the most widely used type in papermaking; •

Global plastic packaging pollution is becoming increasingly serious, and disposable refractory products cause a large amount of white pollution, which goes against the 'double carbon' strategy and the concept of sustainable development. Nanocellulose (Nanocellulose), as a new type of natural biomass nanomaterial, has become a core breakthrough in the field of degradable packaging due to its excellent barrier properties, film-forming properties and environmentally friendly properties. Nanjing Tianlu Nano Technology Co., Ltd. is deeply involved in the research and development, production and sales of nanocellulose, assisting the implementation of the degradable packaging industry and promoting the green upgrade of the industry. 1. Nanocellulose: the core preferred material of degradable packaging. The core requirement of degradable packaging is to balance environmental protection and practicality. Compared with traditional degradable materials such as starch-based and PLA, nanocellulose has significant advantages. Nanjing Tianlu relies on its characteristics to create customized products for multiple industries and realize material value conversion. 1. Extremely environmentally friendly, eliminating white pollution from the source. Nanocellulose is made from agricultural and forestry biomass such as wood, straw, and bamboo.

Against the background of the rise of new energy vehicles and energy storage industries, lithium batteries have become the core carrier of global energy transformation. The technological upgrade of lithium battery separators directly determines the development level of the industry. Due to shortcomings such as insufficient thermal stability and easy shrinkage at high temperatures, traditional polyolefin (PE/PP) separators are difficult to meet the needs of high-safety, high-energy-density lithium batteries. Nanocellulose (CNF/CNC), as a new green new energy material, has become the core choice for separator upgrades with its unique advantages. Nanjing Tianlu Nano Technology Co., Ltd. (hereinafter referred to as 'Nanjing Tianlu') is a domestic professional R&D and production enterprise in the field of nanocellulose lithium battery separators, assisting the green upgrade of the industry. Nanocellulose breaks the shackles of traditional separator technology and injects new momentum into the lithium battery industry by virtue of its core characteristics such as ultra-high thermal stability, ultra-strong mechanical strength, nano-scale porous structure and full life cycle green environmental protection. Nanjing Tianlu, located in Jiangning District, Nanjing, has been deeply involved in the field of nanocellulose for many years, relying on local
