Aqueous aluminium-ion rechargeable batteries (AAIBs) have attracted lots of attention due to their high theoretical capacity, volumetric energy density and low price.
Abstract This work demonstrates the use of a NiCu electrocatalyst prepared by hydrothermal method with different Ni/Cu mass ratios (70:30, 50:50 and 30:70) supported on carbon nanotubes (CNTs), which was studied regards to its electrochemical behavior in ammonia oxidation reaction direct microfluidic fuel cell (DAMFC) performance. XRD SEM‐EDX showed formation alloy while TEM particles size be 15–20 nm. Cyclic voltammetry chronoamperometry that had higher catalytic activity than pure Ni Cu,...
In rechargeable batteries, electron transport properties of inorganics in the solid-electrolyte interphase (SEI) critically determine safety, lifespan and capacity loss batteries. However, heterogeneous interfaces among different solid SEI have not been studied experimentally or theoretically yet, although such exist inevitably. Here, by employing non-equilibrium Green's function (NEGF) method, we evaluated atomic-scale under bias voltage for LiF/Li2O single-component layers them, since LiF...
In this study, a novel cotton-based aluminum-air battery is demonstrated. The designed to be reusable so that sheet of aluminum foil with 0.5 mm thickness can used for tens times by simply replacing the cotton substrate. addition, an inexpensive industrial-grade alloy or waste fed reduce its operation cost. Moreover, unlike conventional which requires complicated flow management system, present only needs small reservoir passively supply water electrode reaction, leading greatly simplified...
This work demonstrates a novel-type paper-based solid electrolyte (PBSE) and its application in Al-air battery, which is targeted for miniwatt applications. Benefited from the solid-form electrolyte, liquid-free operation of battery realized, eliminating potential leakage hazard therefore improving practicability. The PBSE prepared by impregnating gel into porous cellulose paper, followed solution casting process to solidify gel. as-prepared can either be used mechanical rechargeable...
Conventional Al-air battery has many disadvantages for miniwatt applications, such as the complex water management, bulky electrolyte storage and potential leakage hazard. Moreover, self-corrosion of Al anode continues even when flow is stopped, leading to great waste. To tackle these issues, an innovative cotton-based aluminum-air developed in this study. Instead flowing alkaline solution, cotton substrate pre-deposited with solid used, together a small reservoir continuously wet dissolve...
A [email protected] core shell nanoparticles decorated graphene carbon nanotube composite was produced as an anode material for flow through direct methanol microfluidic fuel cell. The characterized by SEM and TEM which reveals that the size of is less than 5nm pore porous electrode 10µm. An orthogonal cell designed a maximum specific power 10.15mW/mg catalyst can be achieved, outperformed most others' works in literature.
