Ladpli et al. used ultrasonic guided waves for the first time to detect the lithium-ion battery, in which the impact of the cycle on the battery was monitored and the reduction of TOF was described in detail with the charge-discharge cycle increasing.
The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually declining characteristic when a lithium battery is operated at a lower discharge rate (such as C/2, C/3, C/5, C/10, etc.).
It is usually expressed in milliamp-hours (mAh) or ampere-hours (Ah). By integrating the lithium battery charge curve and discharge curve, the actual capacity of the lithium battery can be calculated. At the same time, multiple charge and discharge cycle tests can also be performed to observe the attenuation of capacity.
With the development of new energy technology, lithium-ion battery, as a common energy storage and driving structure, has been widely used in many fields. It is significant to accurately monitor and evaluate the state of charge (SOC) and state of health (SOH) of lithium-ion battery.
In common, lithium-ion battery can be regarded as a multi-layer structure and its structural parameters such as internal modulus and density change in the process of charge-discharge cycle and aging. As a result, the SA of response signal can well correspond to the charge-discharge cycle of lithium-ion battery.
The capacity of a lithium battery refers to the amount of charge the battery can store. It is usually expressed in milliamp-hours (mAh) or ampere-hours (Ah). By integrating the lithium battery charge curve and discharge curve, the actual capacity of the lithium battery can be calculated.
