论文摘要
借助锂离子和新兴的替代电池对我们的电力未来的重要性，可以预测新的可持续材料，电解质和完整的电池，这些电池可安全地提供高性能，长寿，能量密集能力至关重要。了解界面，材料的微观结构，影响或限制长期性能的电解质的性质和因素是新电池化学的关键，细胞形态和替代材料。引起这些变化的电化学过程也很难探测，因为它们具有其稳定性和寿命，这可能是纳秒纳秒纳秒时间域。因此，开发和适应捕获这些过程的高分辨率，无损方法证明了具有挑战性，需要最先进的技术。截然不同的进度是非常有希望的，光谱光谱，同步辐射技术，以及能量特定的原子概率概率和微观的方法是不断的，这些方法是在不断的情况下进行的。近年来，许多最有希望的非破坏性方法评估了电极和完整细胞操作中的电池材料特性，界面，过程和反应。
With the importance of Li-ion and emerging alternative batteries to our electric future, predicting new sustainable materials, electrolytes and complete cells that safely provide high performance, long life, energy dense capability is critically important. Understanding interface, microstructure of materials, the nature of electrolytes and factors that affect or limit long term performance are key to new battery chemistries, cell form factors and alternative materials. The electrochemical processes which cause these changes are also difficult to probe because of their metastability and lifetimes, which can be of nanosecond to sub nanosecond time domains. Consequently, developing and adapting high-resolution, non-destructive methods to capture these processes proves challenging, requiring state-of-the-art techniques.Recent progress is very promising, where optical spectroscopies, synchrotron radiation techniques, and energy-specific atom probe tomography and microscopy methods are just some of the approaches that are unravelling the true internal behaviour of battery cells in real-time.In this review, we overview many of the most promising non-destructive methods developed in recent years to assess battery material properties, interfaces, processes,and reactions under operando conditions in electrodes and full cells.
