Most transition metal oxides (TMOs) with medium conductivity and large volume expansion upon lithiation have arelatively poor rate capability and cycling life. To improve the electrochemical performances of electrochemical energystorage devices (EESDs), low-cost non-noble metals can be coupled to TMOs to yield diversified nanostructures, suchas non-noble metal decorated-TMO nanoparticles (NPs) or nanoarrays, non-noble metal-TMO core-shell nanostructures. Notably, in recent years, conductive metal (Cu, Ni, Ti) substrates have been effectively employed as currentcollectors for the direct growth of TMO nanostructures, which have attracted much attention. Thus, non-noble metalTMO materials can be divided into three types: 1) TMOs on non-noble metal substrates (TMO/NM-S), 2) non-noblemetal-TMO (NM/TMO), 3) non-noble metal-TMO on substrates (NM/TMO/S). In this review, we focus on the threetypes of non-noble metal-TMO materials based on their synthetic methods, morphologies and electrochemicalperformances for supercapacitors and rechargeable batteries. Furthermore, future perspectives and challenges of non-noblemetal-TMO materials for EESDs are briefly discussed.
