Summary: Considering use cases and selecting the right features are crucial in developing battery lifetime prediction models. Prediction of cell-to-cell variability between identically cycled cells requires features that are not reliant on cycling conditions. While features encoding cycling conditions can boost model accuracy, they may lead to reduced transferability on identically cycled cells.

Summary: This study reveals that low discharge rate leads to accelerated capacity fade, while high discharge rate results in more significant kinetic loss. It further identifies that the kinetic loss in high discharge cells primarily occurs in the cathode, while accelerated capacity fade in low discharge cells is mainly caused by degradation in the anode. SEM images also indicate worse interphases and dense agglomerated structure due to cycling the anode at a high potential.

Summary: Incremental capacity analysis (ICA) and integrated voltage (IV) methods were both investigated for Li-ion battery state of health (SOH) estimation, using partial charging data. ICA method showed an accuracy of 0.9-2.1% (RMSE) with C/3 charging for all studied cells, and similar accuracy with 1C and 2C charging currents for some cell types. IV method's accuracy was not as affected by increasing charging current as ICA method, with SOH estimation error remaining below 2.0% (RMSE) for all studied cell types at 2C charging.

Summary: Silicon suboxides (SiOx) are potential anode materials for high-energy lithium-ion batteries (LIBs) due to their high specific capacity and stable cycling performance. The crystallinity of Si embedded in the SiO2 matrix significantly influences the electrochemical performance of SiOx. The presence of heat absorbents (KCl and NaCl) during the magnesiothermic reduction of SiO affects the crystallinity of SiOx particles and hence the electrochemical behavior of SiOx during cycling, with KCl leading to superior performance compared to NaCl.

Summary: F-containing functional electrolytes are investigated to improve the performance of Li-metal batteries by generating stable LiF-based solid-electrolyte interphase layers. However, these electrolytes corrode both the Al current collector and the stainless steel (SS) component of the coin cell at high voltages. This study finds that SS corrosion has a greater effect on capacity fading than the Al case, and proposes SS and Al-free pouch-type cells with carbon current collectors and locally high-concentration electrolyte to develop stable cells.

Summary: Lithium-sulfur (Li-S) batteries are considered as promising energy storage devices for portable electronics and electric vehicles due to their low-cost, high-energy density, and minimal environmental impact. However, the low sulfur utilization and short lifespan hinder their performance and commercialization. In this study, Li-S battery cathodes were prepared by blending sulfur (S) with modified multiwall carbon nanotubes (MWCNTs) and poly (acrylic acid) (PAA) as a binder to optimize the electrode composition. The cathode prepared with a 5:4:1 wt ratio of S:oxidized MWCNT:PAA showed the highest discharge capacity of approximately 480 mA h g-1. This work demonstrates the feasibility of using redox mediation to enhance electron accessibility with sulfur loaded on MWCNT.

Summary: During the growth of anodic TiO2 nanotubes with a high layer thickness, nanograss structures are formed on the outermost surface through engraving of the oxide tubes in an F- ion containing electrolyte. These nanotubular layers have a high aspect ratio with bundles of nanograss structures on the tube top and high surface area with anatase crystallites inside. By combining two-step anodization and a rubber polymer binder, freestanding nanotubular layers with nanograssy surfaces and nano-crystalline particles in the tubes were obtained. This nanotubular hybrid membrane exhibited excellent performance in Li-S batteries, delivering a capacity of 618 mA h g(-1) after 100 cycles at 0.1C, thanks to efficient polysulfide trapping and electrolyte perturbation.
