Negative Electrode / Silicon - Carbon Negative Electrode Material





Single - walled carbon nanotubes can be used as conductive additives in lithium - ion batteries, especially for the negative electrode, showing advantages that traditional additives cannot match.

Application in the negative electrode:
The single - walled carbon nanotube dispersion can effectively improve the cycling problem of the silicon - carbon negative electrode. Only 0.05% of the additive amount can bring unparalleled conductivity to the silicon - carbon negative electrode. The ultra - fine and stable single - walled carbon nanotubes completely wrap and interconnect the silicon - carbon negative electrode particles, forming highly conductive and durable connections between them. These long - range connections are very tight and have strong conductivity. Even when the silicon particles expand in the negative electrode and the material starts to crack, through the connection of single - walled carbon nanotubes, the particles still maintain good connections. This can prevent the negative electrode from ceasing to work and greatly improve the cycle life of the battery.
 
Application in the positive electrode:
Due to its unique characteristics, the performance of single - walled carbon nanotubes is superior to other conductive agents. It provides performance in terms of discharge power, energy density, and adhesion safety in lithium - ion batteries. The performance improvement in the positive electrode of lithium - ion batteries is beyond the reach of traditional conductive additives, such as carbon black or multi - walled carbon nanotubes.
 
Single - walled carbon nanotubes possess excellent physical properties, nanoscale dimensions, and chemical universality. They can improve material strength and enhance electrical conductivity. Compared with traditional additives, such as multi - walled carbon nanotubes, carbon fibers, and most types of carbon black, an extremely low addition amount of single - walled carbon nanotubes can significantly enhance the performance of materials.
 
◆  Enhance the mechanical properties of materials;
◆  Bring uniform and permanent electrical conductivity to materials;
◆  Maintain color, elasticity, and other main properties;
◆  Have extremely wide applicability.
 
Due to the ultra - high aspect ratio of single - walled carbon nanotubes, when embedded in the material matrix, single - walled carbon nanotubes can form a three - dimensional reinforced conductive network, and have minimal impact on the original color and other main properties of the material. As a general - purpose additive, single - walled carbon nanotubes can improve the performance of most materials, including thermoplastic plastics, composite materials, rubber, lithium - ion batteries, coatings, etc.
 
Single - walled carbon nanotubes are a general - purpose additive. Due to their extraordinary electrical conductivity, single - walled carbon nanotubes have potential application value in a variety of materials. Single - walled carbon nanotubes are also gradually achieving large - scale production.
