CNT Lithium Battery Materials Shippment

The weather in Xiamen today is great, we also take advantage of this good weather to ship the CNT materials of our regular client's factory.

Like lithium ion battery electrode materials, conductive agents are constantly evolving.

As an important part of the lithium ion battery, the conductive agent, although it occupies a small amount in the battery, it greatly affects the performance of the lithium ion battery, and has very important effect on improving battery cycle performance, capacity development, rate performance, etc. From the earliest zero-dimensional conductive agent carbon black materials to conductive carbon fibers and carbon nanotubes, which are gradually developed later, conductive agents with one-dimensional structure.

Carbon nanotubes, a conductive agent with a one-dimensional structure, increase the contact with the electrode material particles due to its fibrous structure, which greatly improves the conductivity of the electrode and reduces the resistance of the pole piece. CNTs can be divided into single-walled CNTs and multi-walled CNTs. Carbon nanotubes with a one-dimensional structure are similar to fibers in a long columnar shape with a hollow interior. Carbon nanotubes have good electronic conductivity. The fibrous structure can form a continuous conductive network in the active material of the electrode. It is also in the form of point-line contact with the active material, which is useful for increasing the battery capacity (increasing the compaction density of the pole piece) and rate Performance, battery cycle life and reducing battery interface impedance have a great effect. After adding carbon nanotubes, the pole piece has higher toughness, which can improve the peeling caused by the volume change of the material during the charging and discharging process, and increase the cycle life. Carbon nanotubes can greatly improve the penetration ability of the electrolyte in the electrode material.

Therefore, as a conductive agent for lithium ion batteries, the main problem that CNT needs to be solved is the dispersibility of CNT, which is required to be well dispersed in the slurry. At present, it can be solved by high-speed shearing, adding dispersant, making dispersion slurry, and electrostatic dispersion of ultrafine grinding beads. CNT can more effectively improve the overall performance, which makes it a research hotspot and one of the most potential application directions of conductive agents for lithium batteries.
