3D printed microlattice electrode to enhance lithium battery performance
According to foreign media reports, researchers at Carnegie Mellon University and the Missouri University of Science and Technology have developed new methods based on the combination of air jet printing (AJ). In the above, a 3D printed battery electrode was fabricated, which has a 3D microlattice structure to achieve controlled porosity.
The researchers pointed out in the paper that the microlattice structure can greatly increase the capacity and charge and discharge rate of lithium-ion batteries. The additive manufacturing method utilizes 3D printing equipment to create a complex 3D battery architecture that helps optimize the configuration of electrochemical energy storage. According to researchers, the technology can be applied to the industry in the next 2-3 years.
The microlattice structure used in lithium-ion batteries can improve battery performance by reducing the specific capacity by a factor of four and the actual capacity by a factor of two compared to a solid block.
In addition, after completing 40 electrochemical reactions (charge and discharge), the complex 3D microlattice structure remains intact, indicating excellent mechanical properties. These batteries increase the battery capacity at the same weight. In the same way, if the capacity is kept at the current value, the material of the battery will be greatly reduced, which will help to realize the weight reduction of the vehicle battery, and the effect on the traffic application is self-evident.
Researchers at Carnegie Mellon University have independently developed the 3D printing method, created a micro-lattice porous structure, and combined the current airflow printing 3D printing technology.
The research team is working on a more complex 3D structure that can be used as both structural and functional materials.
