Delithiation capacity
WebJun 17, 2024 · Although a high delithiation capacity of 945 mAh⋅g −1 is achieved for CPTCDA–S cathodes in the first cycle, the capacity quickly drops to 370 mAh⋅g −1 after 60 cycles with a low CE of ∼95% (SI … WebCell voltage is a fundamental quantity used to monitor and control Li-ion batteries. The open circuit voltage (OCV) is of particular interest as it is believed to be a thermodynamic quantity, free of kinetic effects and history and, therefore, “simple” to interpret. Here we show that the OCV characteristics
