Short carbon fiber: a driving force for innovation in the field of new energy!

In the global wave of active transition to new energy, innovation in materials science has become the core force to promote this change. Short carbon fiber, as a high-performance material, is showing great application potential in the field of new energy with its unique performance, and has become a key factor in many new energy technology breakthroughs and optimization.

Application in new energy batteries

Electrode material reinforcement

In new energy batteries such as lithium-ion batteries, electrode performance directly affects the energy density, charge and discharge efficiency and cycle life of the battery. The short-cut carbon fiber can be added as an additive to the electrode material to significantly improve the electron conduction rate of the electrode by constructing a conductive network. The results show that the charge and discharge rate performance of the battery can be greatly improved by adding an appropriate amount of short carbon fiber to the lithium iron phosphate cathode material, and the capacity retention rate can be increased by more than 20% under the condition of high charge and discharge rate. This is because the high electrical conductivity of the short-cut carbon fiber promotes the rapid transmission of electrons between the particles of the electrode material, reduces the polarization of the electrode, and makes the battery work more efficiently during high current charging and discharging.

Battery thermal management system optimization

The battery generates heat during charging and discharging. If the heat is not effectively dissipated, the performance and safety of the battery will be affected. Short carbon fiber reinforced composites can be used to manufacture thermal components in battery thermal management systems. Due to the good thermal conductivity of the Short carbon fiber, the heat generated by the battery can be quickly exported and evenly dispersed, and the consistency of the temperature in the battery pack is maintained. For example, the use of short carbon fiber reinforced plastic heat sink, compared with the traditional plastic heat sink, the thermal conductivity is increased by 3-5 times, can more effectively reduce the operating temperature of the battery, extend the battery life, and ensure the stable operation of the battery under various conditions.

Help lightweight new energy vehicles

Body structure parts manufacturing

The driving range of new energy vehicles is significantly affected by the body weight. The short-cut carbon fiber reinforced composite has outstanding advantages in the manufacture of body structural parts. Taking car doors as an example, the use of Short carbon fiber reinforced injection molding process to manufacture doors, compared with traditional metal doors, the weight can be reduced by 30%-40%. At the same time, due to the high strength and stiffness given to the material by the short carbon fiber, the impact resistance of the door is not reduced, but improved. This lightweight design can not only reduce the energy consumption of the car during driving, improve the driving range, but also reduce the brake system burden and improve the vehicle handling performance.
