Advancements in Battery Materials

The doping of metal on carbon can be significantly improved by plasma treatment in two ways: increased dispersion and stronger interactions between metal particles and the substrate, both leading directly to enhanced hydrogen spillover and, thereby, increased hydrogen storage. Thus, the hydrogen storage capacity of activated carbon at 298 K was increased almost 3-fold by doping with 3 wt % of platinum, using a plasma treatment. Without plasma treatment but with H2 reduction, the increase in hydrogen storage was only 54% by doping with 3 wt % of platinum.
