TL;DR: A series of lattice-strained homogeneous NiSx Se1- x nanosheets@nanorods hybrids are designed and synthesized by a facile strategy, providing a new insight to regulate the lattice strain of advanced catalyst materials and further improve the performance of energy conversion technologies.
Abstract: Developing highly-efficient non-noble-metal electrocatalysts for water splitting is crucial for the development of clean and reversible hydrogen energy. Introducing lattice strain is an effective strategy to develop efficient electrocatalysts. However, lattice strain is typically co-created with heterostructure, vacancy, or substrate effects, which complicate the identification of the strain-activity correlation. Herein, a series of lattice-strained homogeneous NiSx Se1-x nanosheets@nanorods hybrids are designed and synthesized by a facile strategy. The NiS0.5 Se0.5 with ≈2.7% lattice strain exhibits outstanding activity for hydrogen and oxygen evolution reaction (HER/OER), affording low overpotentials of 70 and 257 mV at 10 mA cm-2 , respectively, as well as excellent long-term durability even at a large current density of 100 mA cm-2 (300 h), significantly superior to other benchmarks and the precious metal catalysts. Experimental and theoretical calculation results reveal that the generated lattice strain decreases the metal d-orbital overlap, leading to a narrower bandwidth and a closer d-band center toward the Fermi level. Thus, NiS0.5 Se0.5 possesses favorable H* adsorption kinetics for HER and lower energy barriers for OER. This work provides a new insight to regulate the lattice strain of advanced catalyst materials and further improve the performance of energy conversion technologies.

TL;DR: In this paper, the role of carbon as a conductive additive was investigated for LiFePO4 cathodes with different carbon contents and showed that carbon increased the utilization of active material and the electrical conductivity of electrode, but decreased volumetric capacity of electrode.
Abstract: The electrochemical properties of LiFePO4 cathodes with different carbon contents were studied to determine the role of carbon as conductive additive. LiFePO4 cathodes containing from 0 to 12% of conductive additive ~carbon black or mixture of carbon black and graphite! were cycled at different C rates. The capacity of the LiFePO4 cathode increased as conductive additive content increased. Carbon increased the utilization of active material and the electrical conductivity of electrode, but decreased volumetric capacity of electrode. This composition ~LiFePO4 with 3 wt % of carbon and 3 wt % of Graphite! is suitable for HEV application.
