Direct Synthesis of Lithium-Intercalated Graphene for Electrochemical Energy Storage Application

Abstract: A novel approach for bulk synthesis of lithium-intercalated graphene sheets through the reduction of exfoliated graphene oxide in liquid ammonia and lithium metal is reported. It is demonstrated here that as-synthesized lithiated graphite oxide sheets (Li-RGO) can be directly used as an electrode material in lithium batteries. The electrochemical studies on Li-RGO electrodes show a significant enhancement in the specific capacity of the lithium battery over commercially available graphite electrodes. Partial i… Show more

“…Intercalation compounds of inorganic hosts (graphite, clays, di-chalcogenides and others) have also gained renewed interest owing to their unique chemical and physical properties [1][2][3][4][5][6] . De-intercalation of those compounds under certain conditions (such as thermal shock) as well as sonication or volume expansion reactions in the interlayer space lead to the formation of widely used exfoliated graphite [7][8][9][10][11] and two-dimensional (2D) materials with unusual electronic properties [12][13][14][15] .…”

“…4. Other methods use alkali ions [15,16] to intercalate or microwave [17][18][19] width of 30 inches, and the use of Cu instead of Ni led to better controlled growth of mono or bi-layer graphene. Typically, the CVD method refers to thermal CVD (TCVD) but also, other CVDs that use plasma.…”

“…Owning to its unique physical and chemical properties, this material is set to revolutionize the twenty-first century for its wide practical uses, such as in nanoelectronics, (5,6), sensors, (7,8), capacitors, (9)(10)(11), solar cells, (12)(13)(14), fuel cells, (15,16), Li ion batteries, (17)(18)(19), photocatalysis, (20,21), electrocatalysis, (22,23), drug delivery (24,25) and plasmonics (26,27). Given this exceptional level of utility, there is a clear need to prioritize processes that are amenable to the large-scale synthesis of highquality graphene, at low cost and with easy processing methods.…”
