在评估电池配方的可行性以用于商业钠离子电池之前，应用于电池生产的工艺应该得到验证和优化。这篇综述总结了在研究规模上构建钠离子(Na-ion)电池的步骤，重点介绍了可能影响测量的循环性能的参数和技术。对于典型的锂离子(Li-ion)电池，建立了一致的工艺-结构-性能联系，可以指导假设在Na-离子电池中进行测试。液体电解液粘度、混合电极浆料的顺序、电极干燥速度和形成循环特性被发现对实验室电池的报告容量至关重要。基于观察到的加工对电池性能结果的重要性，目前钠离子研究中对新材料的关注应该与对电池组件在生产过程和生产后的机理变化的更深入研究相平衡，以便更好地为这些有前途的电池的未来设计提供信息。更好的电池：这篇综述总结了在研究规模构建钠离子(Na-ion)电池的步骤，重点介绍了可能影响测量的循环性能的变量和技术。在锂离子电池中观察到的工艺-结构-性能联系可能具有指导意义，而当测试用于钠离子电池的新材料时，建议通过独立验证进行参数优化。
Before the viability of a cell formulation can be assessed for implementation in commercial sodium ion batteries, processes applied in cell production should be validated and optimized. This review summarizes the steps performed in constructing sodium ion (Na‐ion) cells at research scale, highlighting parameters and techniques that are likely to impact measured cycling performance. Consistent process‐structure‐performance links have been established for typical lithium‐ion (Li‐ion) cells, which can guide hypotheses to test in Na‐ion cells. Liquid electrolyte viscosity, sequence of mixing electrode slurries, rate of drying electrodes and cycling characteristics of formation were found critical to the reported capacity of laboratory cells. Based on the observed importance of processing to battery performance outcomes, the current focus on novel materials in Na‐ion research should be balanced with deeper investigation into mechanistic changes of cell components during and after production, to better inform future designs of these promising batteries. Better batteries: This review summarizes the steps performed in constructing sodium ion (Na‐ion) cells at research scale, highlighting variables and techniques that are likely to impact measured cycling performance. Process‐structure‐performance links observed in lithium‐ion cells can be instructive, while parameter optimization through independent validation is recommended when testing novel materials for Na‐ion cells.
