“…The electrochemical performance of SIBs is closely related to the properties of electrode materials, especially anode materials (Chen et al, 2018; Fan et al, 2018; Hu A. J. et al, 2018; Liang et al, 2018b,d; Wan et al, 2018; Wei et al, 2018). Recently, Na super ion conductor (NASICON) type NaTi 2 (PO 4 ) 3 has been considered as one of promising anode materials for SIBs owing to its “zero-stress” three-dimensional (3D) framework, high Na + conductivity, and good thermal stability (Kabbour et al, 2011; Wu et al, 2013; Sun et al, 2016; Ye et al, 2017).…”

NaTi2(PO4)3 has attracted great interest as anode material for sodium ion batteries owing to its open three-dimensional framework structure and limited volume changes during the charge and discharge process. However, the poor intrinsic electronic conductivity of NaTi2(PO4)3 needs to be improved for high rate capability. In this work, porous NaTi2(PO4)3 nanocubes anchored on porous carbon nanosheets (NaTi2(PO4)3/C) are designed and developed. This material exhibits a large discharge capacity and good rate capacity including a first discharge capacity of 485 mAh g−1 at a current density of 0.1 A g−1, and 98 mAh g−1 retained at a high rate of 4 A g−1 even after 2,000 cycles. These results suggest that NaTi2(PO4)3/C is a promising anode material for sodium-ion batteries.

“…Graphene has been considered as an ideal electric double layer capacitive material because of ultrathin flexible structure, high surface area (2630 m 2 g −1 ), superior electrical conductivity, and high theoretical capacitance (550 F g −1 ) . However, the electrochemical performance has been primarily hindered by the restacking tendency due to strong Van der Waal force between graphene nanosheets, resulting in the huge decrease of accessible surface area of electrolyte ions.…”

The Road Towards Planar Microbatteries and Micro‐Supercapacitors: From 2D to 3D Device Geometries

The rapid development and further modularization of miniaturized and self‐powered electronic systems have substantially stimulated the urgent demand for microscale electrochemical energy storage devices, e.g., microbatteries (MBs) and micro‐supercapacitors (MSCs). Recently, planar MBs and MSCs, composed of isolated thin‐film microelectrodes with extremely short ionic diffusion path and free of separator on a single substrate, have become particularly attractive because they can be directly integrated with microelectronic devices on the same side of one single substrate to act as a standalone microsized power source or complement miniaturized energy‐harvesting units. The development of and recent advances in planar MBs and MSCs from the fundamentals and design principle to the fabrication methods of 2D and 3D planar microdevices in both in‐plane and stacked geometries are highlighted. Additonally, a comprehensive analysis of the primary aspects that eventually affect the performance metrics of microscale energy storage devices, such as electrode materials, electrolyte, device architecture, and microfabrication techniques are presented. The technical challenges and prospective solutions for high‐energy‐density planar MBs and MSCs with multifunctionalities are proposed.

“…Without using additional components (conductive carbons and binders) or external weighty metal current collectors, free‐standing flexible graphene‐based electrodes present significant advantages on weight, cost, and energy density over traditional electrodes. Recently, many efforts have been devoted to fabricating graphene‐based electrodes to construct flexible batteries and there are some reviews highlighting the development of the field . For instance, Chen et al summarized graphene‐based materials for flexible supercapacitors and LIBs.…”

The emerging flexible electronic devices have stimulated the development of flexible batteries, in which flexible electrodes are indispensable components. Graphene, known for its excellent electrical conductivity and mechanical stability, can be used as an ideal flexible substrate. Recently, many efforts have been devoted to graphene-based electrodes for flexible batteries. Herein, this review summarizes recent advances in the development of graphene-based electrodes for various flexible batteries, including metal-ion batteries (ions of Li, Na, Zn, Al, etc.), lithiumsulfur batteries, and metal-air batteries (Li-and Zn-air batteries). Besides, major challenges and future developments of flexible batteries are also discussed. K E Y W O R D S flexible batteries, flexible electrodes, graphene
