With the increasing demand for lithium-ion batteries, lithium-ion batteries with high energy density and high power density have become one of the research hotspots. Material modification and new material development can effectively increase the energy density of lithium-ion batteries. In addition, the microstructure parameters of the electrode such as porosity, pore size and distribution, tortuosity and electrode composition distribution are also factors that determine the performance of the electrode and battery. Improving the performance of high specific energy batteries by optimizing the electrode structure design has gradually become the focus of attention. The research progress of porous electrode structure design optimization for lithium ion batteries was reviewed in this article, the design factors and preparation methods of porous electrode structure were summarized. Then the future development of electrode structure design optimization and the promotion of novel preparation technologies for large-scale application in the field of high specific energy lithium ion batteries were prospected in the field of high specific energy lithium ion batteries. |
