Summary: A polyhedral hollow structure of cobalt selenide (CoSe2) was synthesized using metal-organic bone MOFs (ZIF-67) as template and precursor. CoSe2 was coated with conductive polymer polypyrrole (PPy) to improve its electroconductibility and limit the outflow of polysulfide compounds. The prepared CoSe2@PPy-S composite cathode showed high reversible capacities and good cycle stability. The structure of CoSe2 and the coating of PPy enhanced the electrochemical performance of the lithium-sulfur cathode material.

Summary: This study experimentally investigates the degradation of electric vehicle lithium-ion batteries (LIBs) at different temperatures and discharge rates, and proposes a new degradation model to more accurately predict the capacity degradation of EV LIBs. The research reveals that the available capacity of LIBs transiently increases with the increase of charge-discharge cycles during the initial stage of battery use. Temperature has a significant impact on the available capacity of LIBs, and alternating changes in ambient temperature can accelerate the degradation of LIBs. The proposed degradation model exhibits higher prediction accuracy compared to the traditional model.

Summary: Recent progress in lithium sulfur batteries (LiSBs) indicates the potential for a mature energy storage system that can replace existing commercial batteries. LiSBs have advantages such as high theoretical energy density, low production cost, and abundant and environmentally friendly raw materials. However, challenges such as sulfur non-conductivity, shuttle effect, and volumetric changes limit their performance. Porous carbon-based matrix materials have been studied as a solution to overcome these challenges and design high-performance cathodes for LiSBs.

Summary: An interlayer nanocomposite (CC@rGO) composed of a graphene heterojunction with CoO and Co9S8 was prepared through a simple and low-cost hydrothermal calcination method for use as a cathode sulfur carrier in lithium-sulfur batteries. The CC@rGO composite consists of a spherical heterostructure evenly distributed between graphene layers, preventing graphene sheet stacking. The introduction of cobalt heterojunction on a graphene substrate increases the reactivity of the composite and improves its electrochemical properties to some extent. The composite exhibits good cycling performance and maintains high discharge capacity in different rate tests.

As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
