Researchers have developed a solid-state material that can stably and efficiently upconvert sunlight- intensity visible light photons to UV light photons. This photon upconversion material can utilize visible light to successfully drive reactions that would conventionally need UV light, broadening the spectrum of utility for the former.
In the race for fast-charging, energy-dense lithium metal batteries, researchers discovered why the promising solid electrolyte version has not performed as hoped. This could help new designs - and eventually battery production - avoid the problem.
Researchers have developed the design and process technology for the world's first battery electrode that significantly improves the performance and stability of batteries used in electronic devices such as smartphones, laptops, and electric vehicles.
