The Future of mobility is Electric (e-Mobility) for sustainable eco-system: Sodium-Ion Battery ( A Technology Beyond Lithium-Ion Battery)

Introduction to electric mobility – Battery on wheels Electric mobility in the 21 st century by Nagmani Transportation and vehicular mobility have been significant aspects of modern civilization, ensuring connectivity and facilitating socio-economical development. The majority of automobiles on the road today run with conventional fossil fuels like gasoline and diesel . In an Internal Combustion Engine (ICE), incomplete combustion results in greenhouse gas (GHG) emissions contributing to 25% of the total GHG emissions worldwide. As the global consensus grew, green and sustainable alternatives emerged towards the electrification of transportation sectors worldwide. However, electric vehicles (EVs) are historically older technologies as compared to ICE-based automobiles. 1 Battery-powered cars first appeared in the early 1800s, followed by electrified locomotives in the 1830s. 2 Patents were granted in England and America in 1840 and 1847 to use electrified rails. 3 ...

Cracking the Hard Carbon Mystery: Study Unveils How Lithium, Sodium and Potassium Ions Are Stored in a Single Carbon Architecture

Research News Cracking the Hard Carbon Mystery: Study Unveils How Lithium, Sodium and Potassium Ions Are Stored in a Single Carbon Architecture Published in: Journal of Materials Chemistry A (Royal Society of Chemistry) DOI: https://doi.org/10.1039/D5TA10571D Article Title: Mechanistic mapping of alkali-ion storage in micro-spherical closed-pore hard carbon: electrochemical, ex situ, and DFT approaches Authors: Nagmani , Deepak Gorai, Priyanka Pal, Raju Kumar Gupta and Sreeraj Puravankara Understanding the "Black Box" of Hard Carbon Hard carbon has emerged as the leading anode material for next-generation sodium-ion batteries, yet one fundamental question has remained unanswered: Where exactly do alkali ions (Li⁺, Na⁺ and K⁺) go inside hard carbon, and why do they behave so differently? Despite years of research, the storage mechanism in hard carbon has remained one of the most debated topics in battery science. Our latest work provides one of the most comprehensive exp...
