“…7,8 3D nanowire/nanotube arrays of negative electrodes have been successfully prepared, showing improved capacities and rate capabilities compared with their planar counterparts. 9,10 However, there are very limited reports on the preparation of 3D-positive electrodes, which is probably due to the difficulty in synthesizing positive electrode arrays. 11,12 LiCoO 2 is the most commonly used cathode material for lithium-ion batteries due to its excellent electrochemical performance and simple synthesis.…”

Three-dimensional microbatteries have emerged as a new direction for powering microelectronic devices, where the threedimensional nanostructured electrode is the key component for microbatteries to achieve high power density and high energy density in a small footprint. In this work, we present a novel approach for fabrication of LiCoO 2 nanowire arrays as threedimensional cathode for microbatteries. Mesoporous low-temperature LiCoO 2 nanowire arrays can be directly prepared by a twostep hydrothermal method and they can be easily converted into chain-like high-temperature LiCoO 2 nanowire arrays through further calcination. The layered LiCoO 2 nanowire arrays exhibit both high gravimetric capacity and areal capacity, while maintaining good cycling stability and rate capability. The facile synthesis and superior electrochemical performance of the three-dimensional LiCoO 2 cathode make it promising for application in microbatteries.

A novel fiber‐in‐tube hierarchical nanostructure of SnO2@porous carbon in carbon tubes (SnO2@PC/CTs) is creatively designed and synthesized though a carbon coating on scalable electrospun hybrid nanofibers template and a post‐etching technique. This 1D nanoarchitecture consists of double carbon‐buffering matrixes, i.e., the external carbon tubular shell and the internal porous carbon skeleton, which can work synergistically to address the various issues of SnO2 nanoanode operation, such as pulverization, particle aggregation, and vulnerable electrical contacts between the SnO2 nanoparticles and the carbon conductors. Thus, the as‐obtained SnO2@PC/CTs nanohybrids used as a lithium‐ion‐battery anode exhibits a higher reversible capacity of 1045 mA h g−1 at 0.5 A g−1 after 300 cycles as well as a high‐rate cycling stability after 1000 cycles. The enhanced performance can be attributed to the wonderful merits of the external carbon protective shell for preserving the integrity of the overall electrode, and the internal porous carbon skeleton for inhibiting the aggregation and electrical isolation of the active particles during cycling.

SnS 2 urchins self-assembled by one dimensional nanorods, being different from the two dimensional flakes, were synthesized by a facile method to work as an anode material in lithium-ion battery. The SnS 2 urchins displayed a stable capacity of 600 mAh g −1 at the current density of 100 mA g −1 after 50 cycles. The SnS 2 urchins showed better cyclic performance and rate capacity compared with SnS 2 flakes. The improved performance was ascribed to the three dimensional structures which can decrease the volume expansion/contraction of SnS 2 during cycling; the fatal drawbacks of SnS 2 were thus mitigated. The facile and economic preparation route may find suitable application to industrial mass production.
