“…The performance has now been evaluated for Co 3 O 4 prepared in powder form using a breadth of synthesis methods such as decomposition of precursors, [88][89][90][91][92][93][94][95][96] solvothermal, [ 97 , 98 ] precipitation, [ 99 , 100 ] growth within hard templates, [ 101 , 102 ] inverse microemulsions, [ 101 , 103 ] high energy mechanical milling (HEMM), [ 101 ] spray pyrolysis, [ 104 ] electrospinning, [ 105 ] citrate-gel [ 106 ] and even through bio-assisted texturation using genetically modifi ed viruses as templates, [ 107 ] or in thin fi lm form made by pulsed laser deposition (PLD), [ 108 ] radio frequency (RF) sputtering, [ 109 ] electrodeposition couples has a theoretical specifi c capacity of 1675 mAh g − 1 of active material and a theoretical specifi c energy 2500 Wh kg − 1 , assuming complete reaction to form Li 2 S, which triggered efforts to utilize it both in non-aqueous [ 160 , 161 ] and polymer [ 162 ] batteries. Unfortunately, what may in practice look like a simple reaction is complicated by the formation of a variety of lithium polysulfi de intermediates, which are partially soluble in the electrolyte, reducing its conductivity, and can eventually shuttle to the negative electrode where they react with lithium and passivate it, all this, among other reasons, [ 163 ] resulting in severe ineffi ciencies.…”

Despite the imminent commercial introduction of Li-ion batteries in electric drive vehicles and their proposed use as enablers of smart grids based on renewable energy technologies, an intensive quest for new electrode materials that bring about improvements in energy density, cycle life, cost, and safety is still underway. This Progress Report highlights the recent developments and the future prospects of the use of phases that react through conversion reactions as both positive and negative electrode materials in Li-ion batteries. By moving beyond classical intercalation reactions, a variety of low cost compounds with gravimetric specific capacities that are two-to-five times larger than those attained with currently used materials, such as graphite and LiCoO(2), can be achieved. Nonetheless, several factors currently handicap the applicability of electrode materials entailing conversion reactions. These factors, together with the scientific breakthroughs that are necessary to fully assess the practicality of this concept, are reviewed in this report.

Electrospinning of nanomaterial composites are gaining increased interest in the fabrication of electronic components and devices. Performance improvement of electrospun components results from the unique properties associated with nanometer-scaled features, high specific surface areas, and light-weight designs. Electrospun nanofiber membrane-containing polymer electrolytes show improved ionic conductivity, electrochemical stability, low interfacial resistance, and improved charge-discharge performance than those prepared from conventional membranes. Batteries with non-woven electrospun separators have increased cycle life and higher rate capabilities than ones with conventional separators. Electrospun nanofibers may also be used as working electrodes in lithium-ion batteries, where they exhibit excellent rate capability, high reversible capacity, and good cycling performance. Moreover, the high surface area of electrospun activated carbon nanofibers improves supercapacitor energy density. Similarly, nanowires having quasi-one-dimensional structures prepared by electrospinning show high conductivity and have been used in ultra-sensitive chemical sensors, optoelectronics, and catalysts. Electrospun conductive polymers can also perform as flexible electrodes. Finally, the thin, porous structure of electrospun nanofibers provides for the high strain and fast response required for improved actuator performance. The current review examines recent advances in the application of electrospinning in fabricating electronic components and devices.

“…The porous Co 3 O 4 microrod electrode delivers a stable reversible capacity around 678 (±5) mAh g -1 during the 10th-50th cycles (Fig. 5b), which is much higher than the capacities of commercial anode materials (graphite 372 mAh g -1 ) and the Co 3 O 4 nanostructures recently reported in Refs [9,12,22,23]. For comparison, sample S2 (Co 3 O 4 bundles) shows a discharge/charge capacity of 288/286 (±5) mAh g -1 after 50 cycles.…”

Porous Co 3 O 4 microrods have been prepared by an ultrasound-assisted route with subsequent calcination. The as-prepared Co 3 O 4 microrods are composed of interconnected nanoparticles with porous characteristics. The ultrasonic irradiation is critical to determine the morphology and the electrochemical performance of the products. When tested as anode material for lithium-ion battery, the porous Co 3 O 4 microrods show improved capacity and rate cycling performance. The reversible capacity of the materials retains 678 (±5) mAh g -1 after 50 cycles at 100 mA g -1 . Even when cycled at various rate for more than 50 cycles, the reversible capacity recovers to 600 (±5) mAh g -1 for the current of 100 mA g -1 . The improved lithium-storage performance can be attributed to the reduced electrochemical reaction resistance due to the unique porous architecture of Co 3 O 4 microrods.
