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

The demand for wound care is evolving from 'basic protection' to 'precise repair and efficient healing promotion'. Traditional dressings have difficulty in adapting to the needs of multiple wounds due to poor air permeability and easy adhesion. The emergence of nanocellulose has broken the technical bottleneck and become the core driving force for the upgrade of functional dressings. Nanjing Tianlu Nano Technology Co., Ltd. (hereinafter referred to as 'Tianlu Nano') is deeply involved in this field, using professional technology to promote the industrial application of nanocellulose in functional dressings, helping wound care enter a new stage of 'green and efficient'. Nanocellulose (especially bacterial nanocellulose BNC) has become an ideal substrate for functional dressings due to its high purity, three-dimensional network structure, excellent biocompatibility and degradability. Tianlu Nano focuses on the research and development and large-scale production of nanocellulose core technology and optimizes the preparation process. The nanocellulose substrate fibers it produces are uniform and stable in performance, and can achieve multi-functional modification, driving iterative breakthroughs in functional dressings from the root.

Nanocellulose is a nanoscale functional material prepared from natural cellulose. It has the characteristics of high specific surface area, excellent mechanical strength, good biocompatibility and degradability. In the field of medical and biomaterials, its unique physical and chemical properties make it a core material for promoting clinical treatment, tissue repair and biomedical innovation. Its application scenarios cover wound care, tissue engineering, drug delivery, medical consumables and medical aesthetic care. 1 Wound care field: Accelerated healing 'smart dressing' wound care is one of the earliest medical scenarios where nanocellulose has been industrialized. The core relies on the high purity and three-dimensional network structure of bacterial nanocellulose (BNC). 1.1 Chronic wound and burn care BNC dressing is breathable, moisture-permeable, and can absorb exudate. It can maintain a moist environment on the wound surface, promote cell proliferation and tissue regeneration, and can shorten the healing time by 30% compared with traditional gauze.
