WebEfficient bifunctional electrocatalysts for hydrogen and oxygen evolution reactions are key to water electrolysis. Herein, we report built-in electric field (BEF) strategy to fabricate a heterogeneous nickel phosphide-cobalt nanowire arrays grown on carbon fiber paper (Ni2P-CoCH/CFP) with large work function difference (ΔΦ) as bifunctional electrocatalysts for … WebMay 1, 2012 · These batteries only work in one direction, transforming chemical energy to electrical energy. But in other types of batteries, the reaction can be reversed. Rechargeable batteries (like the kind in your cellphone or in your car) are designed so that electrical energy from an outside source (the charger that you plug into the wall or the …
