Abstract In recent years, secondary batteries have emerged as a hot research area, with electrodes being one of the key components that significantly impact battery performance. However, traditional coating‐type electrode sheets, which limitations in terms energy and power density, can no longer satisfy current demands for batteries. 3D printing technology, known its low cost, simple operation, rapid prototyping, ease customization, has garnered widespread attention. By applying technology to optimizing their structure design, it is possible create more active sites ion/charge transport channels, thereby enhancing electrochemical performance Herein, this paper reviews currently commonly used storage technologies standards ink formulation. A variety representative printed structures optimization strategies are also listed. addition, materials use, ranging from 0D 3D, covered, including synthesis methods, morphology, contributions It anticipated review will provide valuable insights into rapidly developing field.

The honeycomb configuration has been widely adopted in numerous sectors owing to its superior strength-to-weight ratio, rigidity, and outstanding energy absorption properties, attracting substantial academic attention research interest. This study introduces a biomimetic modular inspired by the variable-density biological enhancement characteristics of tree stem tissues. examined out-of-plane compressive behavior mechanical structures. A numerical model was constructed utilizing finite element technology, enabling simulation studies at varying impact velocities. improved weight-bearing impact-absorbing properties structures are investigated using theoretical analysis computer simulations. It also scrutinizes effects boundary matching conditions on honeycomb’s performance. results indicate that adjusting thickness walls both matrix sub-honeycomb can substantially improve their resistance low-velocity compression impacts. Furthermore, capacity honeycombs during high-velocity impacts is significantly influenced multiple factors: velocity, density structure, distribution wall within primary matrix. Notably, with an optimally designed structure demonstrates high-speed compared conventional equivalent density. These insights underscore potential for advanced designs further advance material performance structural applications.
