Abstract

Layered materials have emerged as promising candidates due to their versatility in applications ranging from biomedicine to photocatalysis to energy storage. These materials exhibit remarkable properties such as high specific capacity and structural stability during charge-discharge cycles, making them vital in advancing battery technologies. We have investigated the performance of Na2Ti3O7 (NTO) as an active electrode material for lithium-ion batteries (LIB),

where multi-walled carbon nanotubes (CNTs) have been used as conductive additives along with carbon black (CB) to form a composite electrode. These additives help in improving conductivity, surface area, electrolyte accessibility, and mechanical properties, leading to enhanced inter-particle connectivity, discharge capacity, cyclic stability, and capacity retention. We have explored NTO as an anode material for both LIB and SIB (sodium-ion battery). We have also investigated Na3V2(PO4)3 (NVP), a NASICON-type material as an electrode material for sodium-ion batteries. NVP was synthesized as a carbon composite (NVP/C) and evaluated in both anodic and cathodic configurations. NVP-A (used as an anode) exhibited superior cyclic stability. Temperature-dependent studies revealed that NVP-A outperformed NVP-C under all conditions. Post-cycling investigations suggested the formation of parasitic reaction by-products which contributed to reduced lifecycle and capacity fading
