Starch Based Hard Carbon

Starch is one of the most abundant renewable Biomaterials and is widely found in a variety of plants. As a typical polysaccharide, Starch has simple composition, high carbon content, and low price. At the same time, compared with other Biomass Precursors, starch exhibits a natural spherical shape, making it a very competitive raw material for the preparation of Hard Carbon.

Starch Based Hard Carbon

Type：ETY-C001-P

Starch is an organic high molecular carbohydrate with high purity. When organic polymer compounds are used as Hard Carbon Sources, they can be combined with specific synthesis methods to obtain Hard Carbon materials with special morphologies. However, the synthesis process is complex and requires controlled methods of dehydrogenation and deoxygenation. Currently, only a few manufacturers in China have mastered this method to make Starch Based Hard Carbon.

Nowadays, as the supply bottleneck of Lithium Resources becomes more prominent and the application scenarios of Secondary Batteries become more abundant, Sodium ion battery has regained market attention. Sodium ion battery has the advantages of low cost and high safety, and may be a strong complement to lead-acid batteries and lithium iron phosphate batteries and balance the price. Compared with the lithium iron phosphate battery material system, the performance bottleneck of Sodium Batteries at the negative end is more prominent. Hard Carbon has a rich sodium storage environment and a higher theoretical sodium storage capacity. Combined with its low price and small volume deformation after embedded sodium , low temperature and good fast charging performance, it has become the first commercially available sodium electrolyte anode material. Bamboo-based hard carbon is a good Sodium battery negative electrode.
