This review explores degradation pathways, failure risks, and mitigation strategies in lithium-ion batteries, with focus on safety and operation in EVs, ESS, and extreme military environments.

Porous carbons were produced by molten salt assisted activation for use in Li–S battery cathode. The best performing composite displayed high sulfur utilization and good electrochemical performance even at high mass loading of sulfur at 5.15 mg cm⁻².

A bilayer coating prepared by sputtering a thin Pt film on Au-electroplated Ti PTL, prevented TiO_x formation, ensure low interfacial contact resistance and long-term stability. The PEMWE cell performance of 1.716 V at 2.0 A cm⁻² was achieved.

Doping lithium into nickel oxide not only improves its electrical conductivity but also facilitates lithium-ion diffusion into the perovskite, enhancing the quality of the absorber and, consequently, the performance of the solar cell.

Mismatched complex oxide thin films and heterostructures based on perovskites have key applications in technologies such as solid oxide fuel cells, batteries, and solar cells because of emerging properties at the interface.

This research analyzes four perovskite solar cell architectures, emphasizing the effects of material selection, absorber thickness, defect and acceptor densities, interface imperfections, and temperature fluctuations on device efficiency.

The Donnan potential difference between the electrodes increases with the exchange of saline solutions. The geometry and operational parameters offer valuable insights for improving energy extraction performance.

In the first lithiation of (001) sulfur surface, lower S₈ rings convert to Li₂S₈. In the second lithiation, however, reaction occurs at upper S₈ rings adjacent to an existing Li₂S₈ or on lower S₈ rings at a distance, forming new Li₂S₈ molecules.
