Summary: In this study, a new method of sodium tungstate-assisted sintering was proposed to fabricate high-performance single-crystal lithium-rich layered oxides (LLOs) cathode materials. The sodium tungstate promotes particle growth and forms a protective coating on the surface of LLOs particles, suppressing side reactions at the cathode/electrolyte interface. Additionally, trace amounts of sodium and tungsten doping stabilize the crystal structure and enhance the diffusion rate of Li+ ions.

Summary: Forty years after the failed introduction of rechargeable lithium-metal batteries and 30 years after the successful commercialization of the lower capacity, graphite-anode based lithium-ion battery by Sony, demand for higher energy density batteries is leading to reinvestigation of the problem of dendrite growth that makes the metallic lithium anodes unsafe. One strategy to mitigate dendrite growth is to deposit thin, tailored, corrosion-passivating coatings on the metallic lithium, instead of allowing the metal to spontaneously react with the organic electrolyte solution to form its passivating solid electrolyte interface (SEI).

Summary: Zero-emission hydrogen and oxygen production is crucial for the UK to achieve net-zero greenhouse gas emissions by 2050. Electrochemical techniques, such as water splitting with renewable energy, offer a unique approach to achieving zero emissions. However, there can be misleading improvements in the reported performance of electrocatalysts due to the use of different connection lengths in screen-printed electrodes. By using electrochemical impedance spectroscopy, the uncompensated ohmic resistance can be overcome, providing more accurate analysis.
