Abstract

Electrochemical devices including lithium/sodium-ion batteries and supercapacitors, as the promising solution to energy storage and environmental issues in the future, have attracted great attention recently due to the rapidly growing demand for non-renewable resources. The common electrode materials, including metal oxides, suffer from low conductivities, which lead to low charge transfer rate during the charge/discharge process and thus poor battery performance such as low specific capacitance/capacity, low rate capability, and poor cycling stability. Therefore, researchers have been searching for various strategies to enhance the conductivity of the electrode materials and thus the performance of lithium/sodium-ion batteries and supercapacitors. In this mini-review, different strategies to enhance the conductivities of the electrode materials would be discussed which will provide researchers various routes to improve the conductivity of the electrode materials in order to improve the performance of electrochemical device.
