And they found that the response to magnetic field attenuated as the number of cycles increased. However, there were still relatively few researches about the influence of magnetic field on the performances of lithium-ion batteries. Magnetic field effect could affect the lithium-ion batteries performance.
Then the effect of the magnetic field effect on the charge–discharge performance and internal resistance of widely used 18650 lithium-ion battery was studied. The results showed that the trends of terminal voltage during charge and discharge process with and without magnetic field are basically the same.
The magnetic characterization of active materials is thus essential in the context of lithium-ion batteries as some transition metals shows magnetic exchange strengths for redox processes which provides pathway to improve the charge-discharge behavior. The interactions of charged particles within electric and MFs are governed by the MHD effect.
For the purpose of studying the performance of the battery to be tested in the magnetic field, the battery used is the 18 650 cylindrical lithium-ion battery. The cathode material is nickel cobalt aluminum ternary material, and the anode material is artificial graphite.
The position of a single lithium-ion battery in a magnetic field. According to Ampere Circuital Theorem: in a magnetic field, the line integral of the H vector along any closed curve is equal to the algebraic sum of the currents enclosed in the closed curve.
The magnetic susceptibility of the active material of LIBs is an important property to explore once the magnetic properties of the transition metal redox processes begin to be correlated to the electrical control (voltage) of LIBs, influencing battery performance.
