Review of Graphene in Cathode Materials for Lithium-Ion Batteries

Abstract

With the development and progress of science and technology, energy is becoming more and more important. One of the most efficient energy sources is lithium-ion batteries. Graphene is used to improve the rate performance and stability of lithium-ion batteries because of its high surface area ratio, stable chemical properties, and fine electrical and thermal conductivity. In this paper, several common cathode materials of lithium-ion batteries, the preparation methods of graphene, and the combination of graphene and polyanion are reviewed and the research direction of graphene application in cathode materials of lithium-ion batteries is prospected.

Graphene: Chemistry and Applications for Lithium-Ion Batteries

“…Pristine graphene, doped graphene, graphene composites such as graphene/metal phosphates, graphene/metal silicates, graphene/metal chalcogenides, etc., are some of the most commonly reported graphene composite cathodes for LIBs. Among them, olivine phosphate (Li2MPO4) and silicate (Li2MSiO4) (M = Fe, Mn, and Co) have the benefits of minimal expense, good electrochemical performance, high stability, and so forth, explored widely as cathode materials in LIBs [94,95].…”

Progress in electrode and electrolyte materials: path to all-solid-state Li-ion batteries

“…Many researchers have significantly focused towards improving the remarkable features of these batteries. Carbon-based nanomaterials, such as, the graphene, carbon nanotubes, and graphene oxide have shown a great potential as a cathode material in energy storage devices [83][84][85].…”

“…Carbon-based nanomaterials, such as graphene, carbon nanotubes, and graphene oxide, have shown great potential as cathode materials in energy storage devices. [85][86][87] The limitation of traditional cathodes (layered, spinel, and olivine) has limited the capacity mismatch with that of silicon anodes (B1000 mA h g À1 ). Thus, to fill this gap, Li-rich oxide (LRO) materials have emerged as a potential alternative to replace future cathodes due to their high theoretical capacity (B300 mA h g À1 ) and high specific energy (B900 W h kg À1 ).…”

Morphology and Chemical Purity of Water Suspension of Graphene Oxide FLAKES Aged for 14 Months in Ambient Conditions. A Preliminary Study

“…Graphene is a two-dimensional, one-atom-thick layer of carbon, in which atoms are oriented in a hexagonal crystal lattice. The promising and appealing properties of graphene-based materials are widely used in many research-oriented fields, like fuel cells [ 1 , 2 ], batteries [ 3 , 4 ], screens [ 5 , 6 ], sensors [ 7 , 8 ], flexible electronics [ 9 , 10 ], tissue engineering [ 11 , 12 ], and membranes [ 13 , 14 ]. Moreover, their unique features result in an increase of materials’ mechanical strength, electrical and thermal conductivity, and surface area and flexibility [ 15 , 16 , 17 ], making them the most preferred choice in experimental procedures.…”
