The applications of microwave processing of electrode materials for Li-ion batteries have been reviewed. This paper intends to insist at the advantages of the microwave processing and its credentials for commercialization. In order to achieve successive commercialization/ industrial application, a systematic understanding of the microwave processing becomes imperative. In the advent of this, an extensive study on the behavior of material in electromagnetic field has been presented. Microwave processing of various materials like lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, lithium titanium oxide and their derivatives, copper bismuth oxide, antimony sulfide, and tin oxide graphite has been reviewed in detail. Also, the dependence of microwave processing in operating frequency, geometry, preheating, soaking time, susceptor material, and single (or) multimode cavity has been reviewed.
