Ru, B Co-doped hollow structured iron phosphide as highly efficient electrocatalyst toward hydrogen generation in wide pH range

“…48,49 In the high-resolution XPS spectrum of P 2p (Fig. 3d), the peak at 132.5 eV correspond to P-O, where the peaks located at 128.6 eV and 129.7 eV were attributed to M-P. 50 The signal peaks at about 483.3 eV and 460.9 eV have been assigned to Ru 3p 1/2 and 3p 3/2 of Ru 0 . The following peaks (487.5 eV and 464.9 eV) are ascribed to Ru(IV) 51 (Fig.…”

Construction of a N,P doped 3D dendrite-free lithium metal anode by using silicon-containing lithium metal

“…6a and n, DOC 100%, at a current density of 1 mA cm −2 ). 26 Li deposited unevenly on the pure Li, forming sparse domains that resembled islands. The surface of Li has pits and blisters when Li has been stripped, and the surface is uneven, which is attributed to the endless dendrite proliferation of the hostless Li (Fig.…”

“…To obtain a strong affinity for Li and a low overpotential of the 3D lithiophobic host/current collectors, further preparatory steps such as injection of a nucleation seed and lithiophilic surface coating are necessary. 26 The growth of Li dendrites is related to several factors of the matrix material, including the diffusion barrier and local current density. 31 In the traditional crystal growth theory, the crystal growth model mainly depends on the nucleation size and the subsequent growth process.…”

“…They form an interface layer to prevent unnecessary side reactions and dendrite propagation. 26 (3) Solid electrolytes and mixed electrolytes have also been reported to significantly inhibit lithium dendrites. Difficulties such as manufacturing thin solid electrolytes, high interface resistance of lithium, and low ionic conductivity have not been still overcome unlike with liquid electrolytes.…”

In situconstruction of polyether-based composite electrolyte with bi-phase ion conductivity and stable electrolyte/electrode interphase for solid-state lithium metal batteries

“…Triggered by the increasing demand for technologies ranging from exible electronics and electric vehicles to electrical grids, [1][2][3] there is an urgent need for a breakthrough in electrochemical energy storage systems. The lithium (Li) metal anode is a very promising candidate for high-energy lithium metal batteries (LMBs), due to its high specic capacity (3860 mA h g À1 ) and ultra-low redox potential (À3.04 V vs.…”
