Unprecedented strong and reversible atomic orbital hybridization enables a highly stable Li-S battery.

ABSTRACT: The shuttle effect and excessive volume change of the sulfur cathode severely impede the industrial implementation of Li-S batteries. It is still highly challenging to find an efficient way to suppress the shuttle effect and volume expansion. Here, we report, for the first time, an innovative atomic orbital hybridization concept to construct the hierarchical hollow sandwiched sulfur nanospheres with double-polyaniline layers as the cathode material for large-scale high-performance Li-S batteries. This hierarchically 3D, cross-linked and stable sulfur-polyaniline backbone with interconnected disulfide bonds provides a new type and strong intrinsic chemical confinement of sulfur owing to the atomic orbital hybridization of Li 2s, S 3p, C 2p and N 2p. Crucially, such atomic orbital hybridizat
