“…Since reversible electrostripping/deposition at room temperature,k nown as the anode reaction, has been achieved in the RTIL electrolyte,the next stage is to discover promising cathode materials that will allow the development of aluminum battery systems.H owever,u pt on ow,n oa luminum battery system has shown an overall electrochemical performance comparable to the current lithium battery systems,b oth the lithium-ion battery [49,50] and the lithiumsulfur battery, [51] because the trivalent reaction medium, Al 3+ ,a lways produces unusual reaction mechanisms different from Li + .F or example,ultrafast-kinetic graphene materials suffer from al ow capacity while highcapacity transition-metal-chalcogen compounds and elements have poor kinetics and inferior cycling stability.I ti st herefore necessary to elucidate the failure mechanisms of cathode reactions and uses this knowledge to guide materials design and modification. In this Section, cathode materials for different aluminum battery systems are introduced, including intercalation reaction materials (graphite and transition-metal-chalcogen compounds) and phase-transfer materials (elements and non-metallic compounds).…”

Aluminum battery systems are considered as a system that could supplement current lithium batteries due to the low cost and high volumetric capacity of aluminum metal, and the high safety of the whole battery system. However, first the use of ionic liquid electrolytes leading to AlCl4− instead of Al3+, the different intercalation reagents, the sluggish solid diffusion process and the fast capacity fading during cycling in aluminum batteries all need to be thoroughly explored. To provide a good understanding of the opportunities and challenges of the newly emerging aluminum batteries, this Review discusses the reaction mechanisms and the difficulties caused by the trivalent reaction medium in electrolytes, electrodes, and electrode–electrolyte interfaces. It is hoped that the Review will stimulate scientists and engineers to develop more reliable aluminum batteries.

“…All three samples reveal the Type-IV isotherm characteristics with the distinctive Type-H3 hysteresis curves (classified by IUPAC). These are indicative of the mesoporous feature in the solid-state material system [38,39,55,56]. Through the BET analysis, the specific surface area (A ss ) was determined to be 64, 822, and 109 m 2 /g for MnO 2 , AC (see also Figure S2a), and MnO 2 -AC, respectively.…”

In the present work, we demonstrated the upcycling technique of effective wastewater treatment via photocatalytic hydrogen production by using the nanocomposites of manganese oxide-decorated activated carbon (MnO2-AC). The nanocomposites were sonochemically synthesized in pure water by utilizing MnO2 nanoparticles and AC nanoflakes that had been prepared through green routes using the extracts of Brassica oleracea and Azadirachta indica, respectively. MnO2-AC nanocomposites were confirmed to exist in the form of nanopebbles with a high specific surface area of ~109 m2/g. When using the MnO2-AC nanocomposites as a photocatalyst for the wastewater treatment, they exhibited highly efficient hydrogen production activity. Namely, the high hydrogen production rate (395 mL/h) was achieved when splitting the synthetic sulphide effluent (S2− = 0.2 M) via the photocatalytic reaction by using MnO2-AC. The results stand for the excellent energy-conversion capability of the MnO2-AC nanocomposites, particularly, for photocatalytic splitting of hydrogen from sulphide wastewater.

HIGHLIGHTS • For the first time, we fully presented the recent progress of the application of NaTi 2 (PO 4) 3 on sodium-ion batteries including nonaqueous batteries, aqueous batteries, aqueous batteries with desalination, and sodium-ion hybrid capacitors. • The unique NASICON structure of NaTi 2 (PO 4) 3 and the various strategies on improving the performance of NaTi 2 (PO 4) 3 electrode have been presented and summarized in detail. ABSTRACT Several emerging energy storage technologies and systems have been demonstrated that feature low cost, high rate capability, and durability for potential use in large-scale grid and high-power applications. Owing to its outstanding ion conductivity, ultrafast Na-ion insertion kinetics, excellent structural stability, and large theoretical capacity, the sodium superionic conductor (NASICON)-structured insertion material NaTi 2 (PO 4) 3 (NTP) has attracted considerable attention as the optimal electrode material for sodium-ion batteries (SIBs) and Na-ion hybrid capacitors (NHCs). On the basis of recent studies, NaTi 2 (PO 4) 3 has raised the rate capabilities, cycling stability, and mass loading of rechargeable SIBs and NHCs to commercially acceptable levels. In this comprehensive review, starting with the structures and electrochemical properties of NTP, we present recent progress in the application of NTP to SIBs, including non-aqueous batteries, aqueous batteries, aqueous batteries with desalination, and sodium-ion hybrid capacitors. After a thorough discussion of the unique NASICON structure of NTP, various strategies for improving the performance of NTP electrode have been presented and summarized in detail. Further, the major challenges and perspectives regarding the prospects for the use of NTP-based electrodes in energy storage systems have also been summarized to offer a guideline for further improving the performance of NTP-based electrodes.
