<italic>In situ</italic> XRD resolves the structural evolution of Na–Cu/Ni/Mn–O system during Na intercalation/deintercalation processes. The introduction Cu<sup>2+</sup> into transition metal lattice is an strategy to prevent P2–O2 phase transitions.
Hollow carbon nanostructures have inspired numerous interests in areas such as energy conversion/storage, biomedicine, catalysis, and adsorption. Unfortunately, their synthesis mainly relies on template-based routes, which include tedious operating procedures showed inadequate capability to build complex architectures. Here, by looking into the inner structure of single polymeric nanospheres, we identified complicated compositional chemistry underneath uniform shape, confirmed that...
The development of high energy electrode materials for lithium ion batteries is challenged by their inherent instabilities, which become more aggravated as the densities continue to climb, accordingly causing increasing concerns on battery safety and reliability. Here, taking voltage cathode LiNi0.5Mn1.5O4 an example, we demonstrate a protocol stabilize this through systematic phase modulating its particle surface.
