Water-soluble binders are demonstrated to provide significantly better capacity, cycle life stability and rate response for NASICON-type NaTi 2 (PO 4 ) 3 Na-ion battery anodes during reversible sodiation compared electrodes made using polyvinylidene difluoride-containing slurries. The role of carboxymethyl cellulose (CMC) on the physical structure chemical interfacial reactions with sodium-poor...

High-energy batteries need significant cathodes which can simultaneously provide large specific capacities and high discharge plateaus. NASICON-structured Na3V2(PO4)3 (NVP) has been utilised as a promising cathode to meet this requirement and be used in the construction of high energy batteries. For a hybrid-ion battery by employing metallic lithium as an anode, NVP exhibits an initial specific...

Using first-principles calculations, we chart the chemical space of 3d transition metal-based NaSICON phosphates with formula NaxMM′(PO4)3 (with M and M′ = Ti, V, Cr, Mn, Fe, Co Ni). Novel compositions were revealed.

Sodium-ion batteries (SIBs) have developed rapidly owing to the high natural abundance, wide distribution, and low cost of sodium. Among various materials used in SIBs, sodium superion conductor (NASICON)-based electrode with remarkable structural stability ionic conductivity are one most promising candidates for storage electrodes. Nevertheless, relatively electronic these makes them display p...

Mn-substitution NASICON-type Na 3+x Mn x V 2-x (PO 4 ) 3 compounds have been extensively studied as a desirable cathode material for sodium-ion batteries (SIBs), due to their higher operating voltage, low cost and weak biological toxicity compared...

Sodium-ion batteries (SIBs) are potential candidates for the replacement of lithium-ion to meet increasing demands electrical storage systems due low cost and high abundance sodium. Sodium superionic conductor (NASICON) structured materials have attracted enormous interest in recent years as electrode safer long-term performance SIBs electric energy smart grids. These a three-dimensional robust...

Abstract We have studied the ionic and thermal transport properties along with thermodynamic key of a Na-ion-conducting phosphate ceramic. The system Na 1+x Al x Ti 2− (PO 4 ) 3 (NATP) = 0.3 was taken as NASICON-structured model which is candidate material for solid electrolytes in post-Li energy storage. commercially available powder (NEI Coorp., USA) consolidated using cold isostatic pressing...

The effect of high-frequency (HF) electric fields on the crystallization and sintering rates of a lithium aluminum germanium phosphate (LAGP) ion conducting ceramic was investigated. LAGP with the nominal composition Li1.5Al0.5Ge1.5(PO4)3 was crystallized and sintered, both conventionally and under effect of electrical field. Electrical field application, of 300 V/cm at 1 MHz, produced up to a ...
