Iron, rhodium-codoped Ni2P nanosheets arrays supported on nickel foam as an efficient bifunctional electrocatalyst for overall water splitting.

Flexible carbon fiber cloth (CFC) is an important scaffold and/or current collector for active materials in the development of flexible self-supportive electrode materials (SSEMs), especially in lithium-ion batteries. However, during the intercalation of Li ions into the matrix of CFC (below 0.5 V vs. Li/Li+), the incompatibility in the capacity of the CFC, when used directly as an anode material or as a current collector for active materials, leads to difficulty in the estimation of its actual contribution. To address this issue, we prepared Ni5P4 nanosheets on CFC (denoted CFC@Ni5P4) and investigated the contribution of CFC in the CFC@Ni5P4 by comparing to the powder Ni5P4 nanosheets traditionally coated on a copper foil (CuF) (denoted P-Ni5P4). At a current density of 0.4 mA cm−2, the as-prepared CFC@Ni5P4 showed an areal capacity of 7.38 mAh cm−2, which is significantly higher than that of the P-Ni5P4 electrode. More importantly, theoretical studies revealed that the CFC has a high Li adsorption energy that contributes to the low Li-ion diffusion energy barrier of the Ni5P4 due to the strong interaction between the CFC and Ni5P4, leading to the superior Li-ion storage performance of the CFC@Ni5P4 over the pristine Ni5P4 sample. This present work unveils the underlying mechanism leading to the achievement of high performance in SSEMs.
