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 majority of research indicates that a magnetic field is beneficial to the whole system and the electrochemical performance of lithium-based batteries, being advantageous to the cathode, anode, and separators. The main mechanisms involved include magnetic force, the magnetization effect, a magnetohydrodynamic effect, spin effect, and NMR effect.
As the power source of new energy vehicle, the lithium-ion battery’s main responsibility is to provide continuous operation power for new energy automobiles and ensure the safe, stable, economical and green operation of vehicles.
Authors in studied the influences of lithium-ion battery cycles on the SEI layer, the state of charge of the anode and its response to the external magnetic field. And they found that the response to magnetic field attenuated as the number of cycles increased.
With the use of miniaturized batteries, the magnetic field allows for the more uniform penetration of batteries, thus leading to fast charging LIBs. Simulation and experimental results show that the magnetic field has a significant effect on the discharge/charge process for LIBs. Fig. 10.
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.
