Compounds called nickelates can conduct electricity without resistance well above absolute zero and at ambient pressure.
The researchers discovered that in LiNiOâ‚‚ batteries, oxygen atoms in the cathode undergo a chemical reaction that makes the material unstable, causing cracks to form. Over time, these cracks weaken ...
Chinese scientists have achieved high-temperature superconductivity in nickel oxide materials under ambient pressure conditions. The discovery establishes nickel-based materials as the third high ...
