Sodium ion battery technology is gradually advancing and can be viewed as a viable alternative to lithium batteries in niche applications. One of the promising positive electrode candidates P2 type layered sodium transition metal oxide, which offers attractive conductivity. However, reversible capacity phases limited by inability directly synthesize stoichiometric compounds with ratio equal 1. To alleviate this issue, we report herein situ synthesis P2-NaxMO2 (x ≤ 0.7, M = ions)-Na2CO3...

Abstract Orthorhombic α‐MoO 3 is a potential anode material for lithium‐ion batteries due to its high theoretical capacity of 1100 mAh g −1 and excellent structural stability. However, intrinsic poor electronic conductivity volume expansion during the charge–discharge process impede it from achieving practical capacity. A novel composite nanobelts single‐walled carbon nanohorns (SWCNHs) synthesized by facile microwave hydrothermal technique demonstrated as high‐performance batteries. The...

Due to natural abundance, low cost, and compatibility with sustainable green technology, Mg3Sb2-based Zintl compounds are comprehensively explored as potential thermoelectric materials for near-room temperature applications. The effective use of these in devices requires both p n-type Mg3Sb2 having comparable efficiency. However, p-type has inferior efficiency compared its counterpart due electrical conductivity (∼103Sm-1). Here, we show that codoping monovalent atoms (Li-Ag, Na-Ag) at the...

Abstract In this study, discarded neem ( Azadirachta indica ) mature-wood twigs are charred at 473 K to yield charcoal ash. Material characterizations reveal that the ash is composed of various minerals and organic functionalities has a flaky, macroporous surface consisting protrusions. Elementary property analyses performed, twig compared characteristically with similar wood-derived, organic, bottom ashes. The inherently gray color (∼50 % absorbance ∼50 reflectance) changes reddish when...
