In this work, an innovative method is proposed during electrode fabrication to improve lithium-ion battery (LIB) performance. Prior works have demonstrated that controlling the microstructure of a LIB electrode can improve its performance by enhancing the transport of lithium ions. It is known that particles tend to form “chains” under the influence of an electric field (EF) due to the dipolar interactions between particles. This paper investigates a unique method that applies an EF combined with conventional tape-casting to improve electrode performance via facile microstructure modification. From electrochemical tests, it is found that the specific capacity can be improved with higher electric field strength. From electrode microstructure analysis, it is revealed that the improved battery performance benefits from the increased porosity of electrodes under the influence of electric field. This work provides a clear framework in which an electric field treatment combined with conventional tape-casting can significantly improve battery performance.
