A cold cathode is a cathode in a gas-filled electron tube that is not heated by a filament. The voltage potential within the tube is sufficient to ionize the gas and cause the current to flow. For ...

Massachusetts Institute of Technology (MIT) researchers have developed a new organic cathode material with an energy density higher than most cobalt-based cathodes. It can charge–discharge in as ...

There is increasing demand for high-performance lithium-ion batteries for energy storage, electric vehicles, and electronic devices. One of the most commonly used cathode materials in these batteries ...

Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes. Layered lithium cobalt oxide, a key ...

Redox Pathways in the O₂-Type Lithium-Excess Cathode. The schematic illustrates the electrochemical processes of the O₂-type Li₀.₇₅[Li₀.₁₅Ni₀.₁₅Mn₀.₇]O₂ cathode during charge and discharge. Sequential ...

In the early part of the 20th century, it was the first name given to electron beams emitted from a negatively charged cathode in a vacuum tube. The term has been used ever since. See CRT. THIS ...

Stratus Materials Inc., a developer and manufacturer of next-generation cathode active materials for lithium-ion batteries, came out of stealth today. The company, previously operating as 33 Tech Inc.

ICL Group announced in the past week that it discontinued its lithium iron phosphate (LFP) cathode facility projects in the US and Spain after the loss of US Department of Energy and European Union ...
