  Multifunctional three-dimensional (3-D) nano-architectures, integrating all
device components within tens of nanometers, offer great promise for next
generation electrical energy storage applications, but have remained
challenging to achieve. The lack of appropriate synthesis methods, enabling
precise 3-D spatial control at the nanoscale, remains a key issue holding back
the development of such intricate architectures. Here we present an approach to
such systems based on the bottom-up synthesis of penta-continuous nanohybrid
monoliths with four functional components integrated in a triblock terpolymer
derived core-shell double gyroid architecture. Two distinct 3 D
interpenetrating networks serving as cathode and current collector are
separated from a carbon anode matrix by continuous, ultrathin polymer
electrolyte shells. All periodically ordered domains are less than 20 nm in
their layer dimensions and integrated throughout the macroscopic monolith.
Initial electrochemical measurements with the Li-ion/S system exhibit
reversible battery-like charge-discharge characteristics with orders of
magnitude decreases in footprint area over conventional flat thin layer
designs.
