Recent Advances in Effective Reduction of Graphene Oxide for Highly Improved Performance Toward Electrochemical Energy Storage

“…Recently, great efforts have been directed toward improving the structural quality and associated properties of RGO powder, through employing high-temperature annealing process to remove defects in RGO to produce highly graphitized graphene. [46][47][48][49][50] The obtained low-defect graphene showed excellent electrical conductivity. In the same principle, GO with moderate degree of reduction was subjected to microwave heating, leading to lowered content of oxygen functional groups and effectively repaired graphene structure.…”

“…[74] The thermal-reduced graphene-based materials were widely researched and applied to obtain low-defect graphene for energy storage devices. This led to excellent improvement in electrochemical performance of such devices as Li-ion batteries (LIBs), [55,[75][76][77][78][79][80][81][82][83][84] Li-air batteries, [85][86][87][88] Li-sulfur batteries (LSBs), [89] Na-ion batteries (SIBs), [81,90] Al-ion batteries (AlBs), [47][48][49][50] and SCs. [91] Zhang et al [83] used graphite oxide (GO) and triphenylphosphine (TPP) as carbon and phosphorus sources for synthesizing phosphorus-doped graphene (PG) by thermal annealing reduction (e.g., 1000°C).…”
