Battery degradation can be described using three tiers of detail. Degradation mechanisms describe the physical and chemical changes that have occurred within the cell. Mechanisms are the most detailed viewpoint of degradation but are also typically the most difficult to observe during battery operation.
Battery degradation can be a serious problem in the automotive industry affecting the vehicles warranty period and compromise an industry's reputation in the business market role . Hence fundamental understanding of degradation mechanisms is critical for the development of reliable life-prediction methods for battery management systems (BMS).
The n-type materials have the potential to offer an economical and sustainable solution for energy storage applications. 17, 20, 36 However, further insights are needed to evaluate the feasibility and performance of these materials in commercial-scale battery systems.
The percentage variation of the battery pack properties refers to the case with the highest active material mass loading.
While many reviews have evaluated the properties of organic materials at the material or electrode level, herein, the properties of n-type organic materials are assessed in a complex system, such as a full battery, to evaluate the feasibility and performance of these materials in commercial-scale battery systems.
This improves the lifetime economics, enables longer warranties 4 and dilutes the environmental impacts associated with raw material extraction and manufacturing. 9,10 Understanding battery degradation is key to increasing operational lifetime.
