An international team of researchers has demonstrated a new way to increase the robustness and energy storage capability of a particular class of “lithium-rich” cathode materials—by using a carbon dioxide-based gas mixture to create oxygen vacancies at the material’s surface. Researchers said the treatment improved the energy density—the amount of…

…electrolytes that enable lithium batteries to run at temperatures as low as -60 degrees Celsius with excellent performance—in comparison, today’s lithium-ion batteries stop working at -20 degrees Celsius. The new electrolytes also enable electrochemical capacitors to run as cold as -80 degrees Celsius—their current limit is -40 degrees Celsius.

…used to make self-healing batteries, electrochemical sensors and wearable, textile-based electrical circuits. The key ingredient for the ink is microparticles oriented in a certain configuration by a magnetic field. Because of the way they’re oriented, particles on both sides of a tear are magnetically attracted to one another, causing a…
