Triple-shelled Mn₂O₃hollow nanocubes: force-induced synthesis and excellent performance as the anode in lithium-ion batteries

Hollow nanospheres composed of titanium dioxide nanocrystals modified with carbon and gold for high performance lithium ion batteries

“…Over the past years, fabrication of electrode materials with hollow micro-/nanostructures has been ubiquitous since their widespread characteristics including high surface areas and void ratios can effectively improve the diffusion kinetics by reducing the penetration pathways of electrolyte and lithium ions into the electrode materials, allowing these materials to exhibit remarkable cycling and rate capability [15,16]. Generally, the universal strategies for the controllable generation of hollow structures have been based on the templating methods, by encapsulating various templates (e.g.…”

One-step synthesis of crystalline Mn2O3 thin film by ultrasonic spray pyrolysis

“…[12,13] While attaining significant interest in many fields of research, dimanganese trioxide has primarily been investigated as a water splitting catalyst, electrodes for lithium ion batteries, and supercapacitors. [14][15][16][17] Based on literature, Mn 2 O 3 has relatively high conductivity, thermodynamic stability and a reported band gap of 1.2eV, which makes it a suitable material for optoelectronics and photovoltaic applications. [18] So far, several deposition techniques of Mn 2 O 3 were reported in literature such as hydrothermal, facile solvothermal, calcination and reduction of MnO 2 .…”

Mesoporous Tungsten Trioxide Polyaniline Nanocomposite as an Anode Material for High‐Performance Lithium‐Ion Batteries

“…Lithium ion batteries have been widely used in portable electronics (including mobile phones,l aptops, and digitala udio players), and are expected to be ap romisingp ower source in electric vehicles due to their superiore nergy density compared to other secondary batteries.
