The present invention provides a battery electrode comprising an active battery material enclosed in the pores of a conductive nanoporous scaffold. The pores in the scaffold constrain the dimensions for the active battery material and inhibit sintering, which results in better cycling stability, longer battery lifetime, and greater power through less agglomeration. Additionally, the scaffold forms electrically conducting pathways to the active battery nanoparticles that are dispersed. In some variations, a battery electrode of the invention includes an electrically conductive scaffold material with pores having at least one length dimension selected from about 0.5 nm to about 100 nm, and an oxide material contained within the pores, wherein the oxide material is electrochemically active.

The present invention discloses a light-diffusion quantum dot nanostructure and an LED component having the same. The quantum dot nanostructure comprises an optical core, an organic ligand layer, a hydrophobic layer, an inorganic encapsulation layer, and a multi-layered water vapor barrier layer. In the present invention, the multi-layered water vapor barrier layer is particularly designed to an onion skin-like structure, so as to facilitate photoluminescence rays radiated from the optical core can emit out of the barrier layer via voids or pores of the onion skin-like structure, such that the uniformity of the spatial light output distribution of the LED component having the quantum dot nanostructures can be obviously enhanced. On the other hand, because the multi-layered water vapor barrier layer can also improve the dispersibility of the light-diffusion quantum dot nanostructures in a colloidal encapsulation of the LED component, the luminous intensity of the LED component is therefore increased.
