The slow redox kinetics of lithium–sulfur batteries severely limit their application, and sulfur utilization can be effectively enhanced by designing different cathode host materials. Herein, we report the hollow porous nanofiber LaNi0.6Co0.4O3 as a bidirectional material for batteries. After Co is substituted into LaNiO3, oxygen vacancies are generated to enhance conductivity enrich active sites material, electrochemical reaction rate further accelerated synergistic catalytic ability Ni elements in B-site site LaNi0.6Co0.4O3. As illustrated kinetic test results, interconversion lithium polysulfides, nucleation Li2S dissolution were significantly enhanced, indicating that battery during charging discharging process. In performance test, initial discharge specific capacity S/LaNi0.6Co0.4O3 was 1140.4 mAh g–1 at 0.1 C, it able release 584.2 5 C. It also showed excellent cycling long cycle with single-cycle degradation only 0.08%. Even under harsh conditions high loaded low electrolyte dosage, still delivers capability.

In this paper, the natural waste pinecone as a carbon precursor for generation of satisfactory sulfur host materials in lithium-sulfur batteries was realized by introducing molybdenum carbide nanoparticles into derived structure. The conductive pinecone-derived doped with N, O reveals an expansive specific surface area, facilitating accommodation higher load. Moreover, integration Mo2C also significantly enhances its chemical affinity and catalytic capacity polysulfides (LiPSs) to alleviate shuttle effect accelerate redox conversion. As result, WPC-Mo2C/S electrode displays excellent electrochemical performance, including low decay rate 0.074% per cycle during 600 cycles at 1 C outstanding (631.2 mAh g-1 3 C). high loading 5.5 mg cm-2, shows area 5.1 cm-2 after 60 0.2 C.
