Summary: The cathode material of a lithium-ion battery plays a crucial role in the durability, capacity, and safety of the battery. LiNiO2 has attracted attention as a potential cathode material for higher capacity due to its ability to extract more lithium at the same voltage compared to LiCoO2. However, it is prone to pyrolysis, which can lead to ignition and explosion hazards. This study investigates possible elemental substitutions to suppress pyrolysis and identifies P, Ta, and W as promising solutions.

Superparamagnetic NixCu1-x nanoparticles were prepared using a sol-gel method and had a Curie temperature in the therapeutic range for use in magnetic hyperthermia. The release of model drugs from the nanoparticles was studied using an in vitro release system and quantified using UV-visible spectrophotometry. The nanoparticles were characterized using various techniques and their biocompatibility was tested on human skin-derived fibroblasts.

Summary: The effect of Li2S deposition on the impedance response of Li-S battery cells was investigated. It was found that Li2S deposit has little effect on the impedance response, mainly due to its porous structure. Additionally, the deposition process of Li2S leads to a decrease in polysulfide species concentration in the electrolyte, resulting in a decrease in chemical capacitance.

Summary: Infiltration of sulfur into microporous carbon enables the use of carbonate-based electrolytes, forming a compact cathode electrolyte interface. The mechanism of sulfur conversion changes to a quasi-solid-state mechanism, resulting in a single sloping plateau of sulfur conversion. The narrow size of pores determines the sulfur maximum ratio within the carbon-sulfur composite. The confinement of sulfur in narrow pores affects its conversion into Li2S2/Li2S due to volumetric changes.

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.

It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. 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.
