Understanding the Electrochemical Performance of FeS2 Conversion Cathodes

David S. Ashby et al.

Summary: Conversion cathodes have the potential to improve energy densities in rechargeable Li+ batteries, but their limited electrochemical stability and power density have hindered their practical use. In this study, we investigate the effects of cell fabrication, electrolyte interaction, and current density on the electrochemical performance of FeS2/Li batteries. The capacity loss is primarily attributed to the large volume changes during (de)lithiation, leading to the degradation of the conductive matrix. However, by applying external pressure and increasing current density, the capacity loss and polysulfide loss can be minimized.

Temperature-Dependent Reaction Pathways in FeS2: Reversibility and the Electrochemical Formation of Fe3S4

Grace Whang et al.

Summary: This study investigates the rechargeable Li-FeS2 system using various characterization techniques and an ionic liquid electrolyte. The results reveal new reaction pathways and products during the initial lithiation and subsequent cycling of FeS2. It is found that Li2S and hexagonal FeS are formed as intermediate phases during the initial lithiation, and greigite (Fe3S4) is produced as a charge product during the rechargeable reaction, which differs from previous reports. The formation of Fe3S4 is dependent on temperature and the availability of sulfur. Upon further cycling, Fe3S4 transforms to a lower sulfur content iron sulfide phase. The findings highlight the importance of retaining sulfur in the active material for capacity retention.

Utilizing computer vision and artificial intelligence algorithms to predict and design the mechanical compression response of direct ink write 3D printed foam replacement structures

Devin J. Roach et al.

Summary: This study introduces a novel methodology for determining the mechanical compression response of 3D printed foam replacement structures (FRS) using AI. By training an artificial neural network (ANN) on measurement data from a small number of samples, computer vision algorithms can make inferences about foam compression characteristics from a single cross-sectional image. A genetic algorithm (GA) is then used to generate the AM printing parameters needed to achieve a desired compression response from a DIW printed FRS, offering a fully autonomous design and analysis approach for additively manufactured structures.
