Research progress on modified Zn substrates in stabilizing zinc anodes

Abstract

The future demand for large-scale electrochemical energy storage devices has spawned various types of batteries, among which aqueous zinc-ion batteries (ZIBs) have gained much attention due to their safety, affordability,...

Recent progress in aluminum anodes for high-performance rechargeable aqueous Al-ion batteries

“…Recently, rechargeable batteries based on sodium, 8 potassium, 9 magnesium, 10 calcium, 11 zinc 12 and aluminum ions 13 have been proposed as promising alternatives to LIBs. Among them, rechargeable aqueous aluminum-ion batteries (AIBs) are the most promising alternatives because of the following advantages: (1) AIBs can be assembled under ambient conditions and do not require harsh oxygen-free and water-free conditions; this reduces their raw material and manufacturing costs; (2) the electrolyte used in AIBs is non-toxic, non-volatile, non-flammable, and hence environmentally friendly; (3) the high ionic conductivity of the electrolyte affords AIBs a fast charging and discharging capability; (4) AIBs have high intrinsic safety and tolerance against external impact and misoperations.…”

Progress in stabilizing zinc anodes for zinc-ion batteries using electrolyte solvent engineering

“…4 The improved safety, simple operating conditions, resourcefulness, and cost-effectiveness of rechargeable aqueous Zn-ion batteries (ZIBs) make them promising alternatives to LIBs. 5–8 In addition, owing to their high theoretical capacities (820 mA h g −1 and 5854 mA h cm −3 ), low redox potential (−0.763 V vs. the standard hydrogen electrode (SHE)), high safety, and abundant zinc resource, ZIBs are promising candidates for next-generation battery systems. 9 In contrast to other active metals (Li, Na, K, Ca, etc .…”

Hydrogel-stabilized zinc ion batteries: progress and outlook

“…With the advancements in sensor technology and flexible display technology, there is a growing and urgent demand for energy storage devices (ESDs) compatible with these developments. 1–3 In addition to providing a consistent power supply, ESDs for wearable electronics must also possess the necessary flexibility. Traditional ESDs, due to their rigidity, bulkiness, and cumbersome nature, are unable to meet the requirements of wearable electronics.…”
