Kinetically Dormant Ni-Rich Layered Cathode During High-Voltage Operation.

The degradation of Ni-rich cathodes during long-term operation at high voltage has garnered significant attention from both academia and industry. Despite many post-mortem qualitative structural analyses, precise quantification of their individual and coupling contributions to the overall capacity degradation remains challenging. Here, by leveraging multiscale synchrotron X-ray probes, electron microscopy, and post-galvanostatic intermittent titration technique, the thermodynamically irreversible and kinetically reversible capacity loss is successfully deconvoluted in a polycrystalline LiNiMnCoO cathode during long-term charge/discharge cycling in full cell configuration.

Effects of Light Intensity on the Growth and Biochemical Composition in Various Microalgae Grown at High CO Concentrations.

In modern energy, various technologies for absorbing carbon dioxide from the atmosphere are being considered, including photosynthetic microalgae. An important task is to obtain maximum productivity at high concentrations of CO in gas-air mixtures. In this regard, the aim of the investigation is to study the effect of light intensity on the biomass growth and biochemical composition of five different microalgae strains: , , , , and .
