Summary: The traditional polyolefin separators used in lithium-ion batteries have limitations such as poor wetting of electrolytes and insufficient thermal stability. To overcome these limitations, a modified phase inversion technique was developed to coat polyolefin separators with poly(ether ether ketone) (PEEK) efficiently and durably. The PEEK-coated polyolefin separators exhibit comparable mechanical properties with unmodified separators, as well as outstanding thermal stability and enhanced ionic conductivity, leading to significant improvement in the electrochemical performance of prototype half cells. This modified technique provides a practical solution for next-generation separator materials.

Summary: This study investigates the mechanical response of a battery separator and its impact on battery performance. Simulating the displacement and pore pressure of the separator under different charge/compression rates, it is found that the stress-strain curve of the separator exhibits a wave pattern in the fully dynamic model, while this phenomenon is not observed in the quasi-static model. The maximum displacement and pore pressure increase with the compression rate, and the pore pressure fluctuates during compression in the fully dynamic model.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
