“…Compared to the spectrum of Na 4 Mn 9 O 18 , Na 4 Mn 9 O 18 -RGO contained two carbon-related bands at about 1352 (D-band) and 1594 cm −1 (G-band). These bands could be due to defective or disorder carbon and graphitic carbon in RGO, respectively [28,29]. …”

An aqueous sodium ion battery (ASIB) with metal Zn as anode and Na4Mn9O18-reduced graphene oxide (Na4Mn9O18-RGO) as cathode has been developed. In this work, spherical Na4Mn9O18-RGO composite particles were prepared via spray drying. The aqueous battery exhibits stable cyclability and high specific capacities. Typically, a high initial discharge capacity of 61.7 mAh·g−1 is attained at a high current rate of 4 C, and a stabilizing reversible capacity of 58.9 mAh·g−1 was obtained after 150 cycles. The network interlaced by RGO sheets provided fast electron conduction paths and structural stability to accommodate the mechanical stresses induced by sodium insertion and extraction, so the Na4Mn9O18-RGO electrode displayed superior electrochemical performance in the ASIB.

“…34,36 According to the literature, the D band frequency will be higher when graphene is doped by nitrogen atoms, and the G band will shi to higher frequency when graphene is stacked fewer layers. 15,37 Compared with the Raman spectrum of RGO, D-and G-bands locations of NGCA are higher by 4.93 cm À1 and 6.5 cm À1 , respectively. The Raman results conrmed that nitrogen atoms have been successfully introduced into graphite crystal lattice that would improve the homogeneous distribution of graphene and CNTs, which is consistent with XRD and SEM analyses.…”

“…The proposal of transition metal oxides for energy storage [154,155,156] has been given a lot of attention. Superimposing transition metal oxides on carbonaceous materials, such as reduced graphene oxide (rGO), opens challenges of creating an efficient electrode possessing optimal material characteristics [157,158]. Superimposing CeO 2 with carbonaceous material results in uniquely enhanced characteristics.…”

Rechargeable batteries are attractive power storage equipment for a broad diversity of applications. Lithium-ion (Li-ion) batteries are widely used the superior rechargeable battery in portable electronics. The increasing needs in portable electronic devices require improved Li-ion batteries with excellent results over many discharge-recharge cycles. One important approach to ensure the electrodes’ integrity is by increasing the storage capacity of cathode and anode materials. This could be achieved using nanoscale-sized electrode materials. In the article, we review the recent advances and perspectives of carbon nanomaterials as anode material for Lithium-ion battery applications. The first section of the review presents the general introduction, industrial use, and working principles of Li-ion batteries. It also demonstrates the advantages and disadvantages of nanomaterials and challenges to utilize nanomaterials for Li-ion battery applications. The second section of the review describes the utilization of various carbon-based nanomaterials as anode materials for Li-ion battery applications. The last section presents the conclusion and future directions.
