Electrochemical analysis is a technique used to analyze the performance of lithium-ion batteries. It involves measuring the voltage and current of the battery during charging and discharging cycles. This information can be used to determine the battery's capacity, energy efficiency, and other performance characteristics. It can also be used to detect any potential issues with the battery, such as short circuits or overcharging.
Its useful to evaluate basic properties, especially at the development stage of new electrodes and electrolytes.
Electrochemical analysis is a common method used to study the performance and stability of lithium-ion batteries. There are several techniques used in electrochemical analysis of lithium-ion batteries, including:
- Cyclic voltammetry: This technique measures the potential of a battery as it is charged and discharged, and can be used to determine the capacity, charge-discharge efficiency, and kinetics of lithium-ion intercalation and de-intercalation.
- Electrochemical impedance spectroscopy: This technique measures the resistance of a battery to an applied voltage, and can be used to determine the charge transfer resistance, impedance of the electrodes, and the state of charge of a battery.
- Galvanostatic charge-discharge testing: This technique measures the current flowing through a battery as it is charged or discharged, and can be used to determine the capacity, coulombic efficiency, and rate capability of a battery.
- Electrochemical quartz crystal microbalance: This technique measures the mass of a battery as it is charged or discharged, and can be used to determine the capacity and rate capability of a battery.
- X-ray diffraction: This technique measures the crystal structure of a battery as it is charged or discharged, and can be used to determine the phase transformation of lithium-ion intercalation and de-intercalation.
