The invention relates to nano praseodymium oxide lubricating oil additive

The technical problem to be solved by the invention is to provide an energy saving and environmental protection rare earth lubricating oil additive. The rare earth lubricant additive has good wear resistance and self – healing properties. In order to solve the above technical problems, the invention provides a nano praseodymium oxide lubricating oil additive, which is characterized in that it contains nano praseodymium oxide after surface modification. Preferably, the lubricating oil additive preparation materials include: Nano praseodymium oxide 15wt. %; Surfactants 85wt. [...]

Lithium metal battery with flexible Lithium lanthanum zirconium oxygen LLZO electrolyte sheet

Researchers at Tokyo State University have developed a new method for preparing flexible ceramic electrolyte sheets for lithium-metal batteries. They mixed garnet ceramics, polymer binders and ionic liquids to produce a quasi-solid, flake electrolyte. The synthesis is performed at room temperature, requiring much less energy than existing high-temperature (>1000°C) processes. It can operate over a wide temperature range and is a promising battery electrolyte for, for example, electric cars. Fossil fuels account for most of the world’s energy needs, including [...]
