Abstract
AbstractTo improve lithium‐ion batteries further, novel concepts for the reproducible preparation of highly structured bicontinuous battery electrodes are required. With this in mind, the main focus of this work is based on the block copolymer template‐directed synthesis of metal nanofoams suitable for the rational study and design of the final conductive matrix through molecular engineering of the starting polymer. As a proof of concept, diverse MnO2 electrodes with nickel foam as substrates are prepared and morphologically and structurally characterized by means of SEM, Raman spectroscopy, and XRD. To investigate the electrochemical properties of the prepared MnO2–nickel foam electrodes, cyclic voltammetry and galvanostatic cycling experiments, including C‐rate tests, are performed and the obtained results are discussed with respect to the deposition time. Compared with the reference, namely, bulk MnO2–nickel foil electrodes, superior electrochemical characteristics, particularly regarding C‐rate capability and long‐term cycling stability, are achieved, which is attributed to better dimensional stability of the composite electrode.
