This is the first report on the preparation of highly crystalline Li4Ti5O12 with a small particle size of ∼20 nm using a low synthesis temperature (500 °C).
Substituting electroinactive Al3+ into vanadium ferrite aerogels boosts capacity to battery-relevant levels but in a material that expresses pseudocapacitive character and high-rate performance.
An external force field-assisted electrochemical exfoliation method was adopted to produce few-layered bismuthene nanosheets (FBNs). These FBNs exhibited a high rate performance and ultra-long cycle life for KIBs anode.
