New insights into the effects of available space characteristics within graphite-based anodes on the accessibility of solvated Li-ions under fast charging conditions

Jaewook Kim et al.

Summary: This study investigates the accessibility of lithium ions within graphite-based anodes for energy storage materials. By modifying the characteristics of channels and surface pores, the solvated lithium ion accessibility is enhanced. The optimal point is determined through analysis, providing insights on how changes in space characteristics affect electrochemical performance.

Role of silicon-graphite homogeneity as promoted by low molecular weight dispersants

Beth L. Armstrong et al.

Summary: This study found that polymers with the same chemical repeat structure as high molecular weight poly acrylic acid (PAA) and lithium poly acrylic acid (LiPAA) binders, but with low molecular weight, perform the best when used as dispersants in silicon-graphite electrodes. On the other hand, electrodes formulated using PAA had good dispersion but performed the worst in cycling. The binder was found to be unevenly distributed in the electrode, with local regions accommodating volume expansion during cycling.

Influence of Laser Structuring and Calendering of Graphite Anodes on Electrode Properties and Cell Performance

Lucas Hille et al.

Summary: This study explores the influence of calendering and laser structuring on the pore structure and electrochemical performance of electrodes. Laser structuring was found to release superficial pore clogging caused by calendering and to result in binder agglomerates on the electrode surfaces. Structured electrodes showed higher porosities than unstructured counterparts, but no significant change in the pore size distribution was detected. Electrochemical impedance spectra revealed increasing ionic resistances and tortuosities for decreasing electrode porosities. Laser structuring significantly reduced the diffusion limitations of lithium-ion at all porosity levels. Furthermore, electrode structuring showed potential for improving performance at high currents.

Li-Ion Battery Electrode Contact Resistance Estimation by Mechanical Peel Test

John E. Vogel et al.

Summary: The electronic properties of Li-ion battery electrodes, such as bulk conductivity and contact resistance, are crucial for cell performance and fast-charging capability. This study compares the contact resistance and mechanical peel strength of different commercial-grade cathodes and anodes. It was found that peel strength correlates well with contact resistance in a carefully curated data set, but may not accurately reflect electrical properties when there is significant variation in electrode composition.

Calendar aging of silicon-containing batteries

Josefine D. McBrayer et al.

Summary: Silicon-containing batteries are gaining popularity in the mass market, but the calendar aging behaviors of silicon anodes have not been well studied. Researchers are discussing the challenges surrounding the long-term stability of silicon anodes for lithium-ion batteries, especially in high-energy batteries for automotive applications. Future research should focus on assessing and mitigating the time-dependent degradation of silicon-containing batteries to fully realize their benefits.
