CNT encapsulated nickel-doped hollow porous manganese oxide scaffold as a sulfur cathode host for Li-S battery applications.

ABSTRACT: Recently, lithium-sulfur batteries have captivated those in the energy storage industry due to the low cost and high theoretical capacity of the sulfur cathode (1675 mA h g^-1). However, to enhance the practical usability of Li-S batteries, it is crucial to address issues such as the insulating nature of sulfur cathodes and the high solubility of lithium polysulfides (LiPS, Li₂S _x , 4 ≤ n ≤ 8) that cause poor active sulfur utilization. Designing innovative sulfur hosts can effectively overcome sulfur bottlenecks and achieve stable Li-sulfur batteries. This study presents novel hollow porous structures of Ni-doped MnO₂ encapsulated with multi-walled carbon nanotubes (CNTs) used as an efficient host material for a sulfur cathode. These
