Progress in electrode and electrolyte materials: path to all-solid-state Li-ion batteries

Abstract

This review presents a brief scenario about the development of cathodes, anodes, and electrolytes for the next generation of Li-ion batteries (LIBs) and supercapacitors for future energy technologies. Specific capacity...

Highly Flexible PEDOT Film Assembled with Solution-Processed Nanowires for High-Rate and Long-Life Solid-State Supercapacitors

“…The ever-growing wearable consumer electronics have accelerated intensive explorations of various electrochemical energy storage systems. Supercapacitors have been recognized as one of the promising energy storage devices in powering various wearable electronics by virtue of their merits of light weight, rapid charging–discharging rate, and extreme cycling stability. − However, traditional supercapacitors composed of activated carbon and an aqueous electrolyte cannot meet the increasing requirements of modern flexible electronics. Hence, exploration of lightweight supercapacitors that can store energy under bendable, stretchable, and even compressible conditions is highly demanded. , It is believed that the performance of a supercapacitor is dominated by the properties of electrode materials.…”

Improved reversibility of lithium deposition and stripping with high areal capacity under practical conditions through enhanced wettability of the polyolefin separator to highly concentrated electrolytes

“…Li metal is considered to be one of the most attractive negative electrode materials for high energy density rechargeable batteries because of its high theoretical capacity (3860 mA h g À1 ) and low standard electrode potential (À3.04 V vs. SHE). [1][2][3][4][5] However, its practical application has been hampered by the growth of Li dendrites during repeated Li deposition/stripping and the low coulombic efficiency due to the side reactions between Li metal and the electrolyte. The solid electrolyte interphase (SEI) formed by the reductive decomposition of the electrolyte on the Li metal surface, which is a Li + -ion-conductive but electronically insulating passivation layer, is one of the most critical factors that strongly affects the morphology and reversibility of the Li metal electrode.…”

Stacked vanadium pentoxide–zinc oxide interface for optically-chargeable supercapacitors

“…5–7 The metal oxides are well known for their high charge storage capabilities when used in a heterostructure with carbon and metal–organic frameworks (MOF). 8–12…”

“…[5][6][7] The metal oxides are well known for their high charge storage capabilities when used in a heterostructure with carbon and metal-organic frameworks (MOF). [8][9][10][11][12] Among these materials, the low-cost ZnO shows intriguing characteristics such as high carrier mobility, long carrier diffusion, ease of synthesis on substrates, and non-toxicity. 13,14 As a result, ZnO has been widely used in charge transfer applications such as photovoltaic, 15 photocatalysis, 16 and gas sensors.…”
