Customer ServiceThe activation energy of the battery sample can be obtained by exponential fitting. In the experiment, the activation energy of samples 1–4 is basically around 0.55 eV, which is consistent with the activation energy range (0.31–0.94 eV) of the 18 650 battery reported in the literature .
In addition, the SOH of samples 1–4 covers the range of 80%–100% of the battery, and their activation energy is basically stable at 0.55 eV, which indicates that the activation energy is not affected by the aging degree of the battery during normal use.
Here we propose a method to obtain the activation energy of a battery using direct current impedance spectroscopy (DCIS), which enables the stability diagnosis of the charge transport process. DCIS is a time-domain impedance spectroscopy technique.
Activation energy is the energy barrier that lithium-ions need to overcome when passing through the interface between the electrode and the electrolyte, and is an important indicator of the lithium-ion transport capacity at the interface , , , .
If the protection circuit or the detection cabinet is out of control, the charging voltage will be greater than 5V, causing the electrolyte decomposition, violent reaction inside the battery, rapid rise of internal pressure of the battery. Eventually the battery explodes.
2. Direct current impedance spectroscopy During the initial cycle charge and discharge of lithium batteries, some lithium-ions will react with non-aqueous solvents to form a solid electrolyte interphase (SEI) film on the electrode surface, preventing the continued decomposition of the electrolyte in the carbon electrode , , .
