Summary: A novel in situ self-catalyzed synthetic strategy is explored to prepare graphitic carbon nanotubes (CNTs) wrapped and amorphous nanocarbon shells coated LiFePO4 microclews (LiFePO4@C@CNT) at one-step. The results show that the in situ intergrowths of CNTs and LiFePO4@C could be realized by the catalytic effect of Fe3C nanoparticles based on the tip-growth mechanism. The as-prepared LiFePO4@C@CNT-5 composite exhibits excellent electrochemical performance.

Summary: This paper investigates the aging behavior and mechanism of cylindrical LFP batteries by designing a cross-comparison aging test, which uses three constant current and two different dynamic working conditions for accelerated aging at high temperature. The aging behavior and mechanism are quantitatively studied through in-situ electrochemical test and ex-situ Post-Mortem methods. External characteristic parameters such as capacity, internal resistance, and open circuit voltage are periodically checked during the long-term cycle of the battery. This multiscale analytical method enables a detailed understanding of the performance loss process, guiding performance prediction and safety diagnostics.

Summary: The reversible cycling performance of silicon (Si) in lithium-ion batteries is a major concern. This study proposes a solution by coating Si particles with a conductive biphenyl-polyoxadiazole (bPOD) layer, which enhances the electrochemical process and prolongs the battery lifespan. The bPOD coating acts as a mixed ionic-electronic conductor, inhibiting the growth of the solid electrolyte interphase (SEI) and improving ion/electron transport capacity. The 3D porous structure of the coating also provides stability against volume variation. The resulting lithium-ion battery exhibits high reversible specific capacity and excellent rate capacity.
