The Guangdong Patent Award is the highest level official honor of the provincial government in the field of intellectual property in Guangdong Province. The rigor of its selection process and the benchmark of the selected results determine that it is an authoritative benchmark for testing the core technology value and industrial driving ability of enterprises. This year's selection is based on originality, breakthrough, and driving force as the core criteria, adhering to the principle of selecting the best from the best. Through layers of selection from hundreds of thousands of patents and tens of thousands of scientific and technological innovation enterprises in the province, only 40 silver awards were ultimately awarded, with a selection rate of less than 1%. Kaijin has successfully broken through with its core patents, and this honor is the most authoritative official recognition of the company's technological strength.

The present invention patent uses natural, low-cost, and high specific surface area cationic layered clay minerals as templates. After proton exchange, the cationic polymer can be tightly adsorbed on its surface, and then coupled with chitosan to form a three-dimensional network structure. This structure is preserved during the carbonization process, providing a continuous electron transport pathway. Meanwhile, cationic polymers can generate oxides and gases during high-temperature decomposition, resulting in surface micro oxidized porous carbon based materials rich in nanopores and holes. This material has broken through the theoretical lithium storage capacity bottleneck of traditional graphitized negative electrode materials, and thanks to its excellent interface characteristics, it greatly improves the cycling performance of batteries, achieving a synergistic breakthrough in performance upgrading, green low-carbon and industrial applications.
