Customer ServiceThe discharge characteristics of lithium-ion batteries are influenced by multiple factors, including chemistry, temperature, discharge rate, and internal resistance. Monitoring these characteristics is vital for efficient battery management and maximizing lifespan.
Understanding the Discharge Curve The discharge curve of a lithium-ion battery is a critical tool for visualizing its performance over time. It can be divided into three distinct regions: In this phase, the voltage remains relatively stable, presenting a flat plateau as the battery discharges.
The charging and discharging processes of the battery are optimized. The capacity degradation is unfavorable to the electrochemical performance and cycle life of lithium-ion batteries, but the systematic and comprehensive analysis of capacity loss mechanism, and the related improvement measures are still lacking.
Lithium-ion batteries (LIBs) are widely used in new energy vehicles because of their high specific capacity, good energy density, and low self-discharge rate. However, they also have various disadvantages, such as the poor durability [1, 2] that the energy and power of lithium-ion batteries will decrease over time.
Electrode materials that enable lithium (Li) batteries to be charged on timescales of minutes but maintain high energy conversion effi-ciencies and long-duration storage are of scientific and technolog-ical interest.
With the increase of discharge rate, the deintercalation amount of lithium-ion per unit of time increases. A larger concentration gradient will be formed inside the particles to balance the increase of ion deintercalation rate, resulting in an increased internal stress and aggravating the fracture of the particles.
