: Tardive practical development of lithium-sulfur (Li-S) batteries faces two fatal nuisances, the grievous shuttle effect of sulfur electrodes as well as rock-ribbed Li dendrites, which results in undesired cycling lifespan and the potential safety hazard. Diversified electrocatalytic materials are employed to enhance polysulfides conversion kinetics and subsequently restrain shuttle effect. Here, pyrite-type cation regulation strategy is applied to motivate the electrochemical catalysis capability of bimetallic sulfide by regulating the cation ratio of Co and Ni ions. The reformative bimetallic sulfide with Co to Ni ratio near 2:1 shows stronger chemical adsorption capability towards lithium polysulfides in contrast to pristine NiS 2 , which resulted from the strong contribution of metal oxide layer. The comparable electrochemical kinetics and electrochemical performances of Li-S batteries with CNS-2/CP interlayer show in the aspects of low polarization voltage, high lithium ion diffusion rate, high discharge capacity, as well as better rate performances. These results demonstrate cation regulation could be an efficient strategy for material design to optimize the surface physicochemical properties of iron pyrite for boosting the cycle durability of Li-S batteries

: To resolve the problem of the imbalance between micro-Combined Heat and Power (m-CHP) supply and demand, a district energy network has been established based on residential m-CHP units powered by natural gas-fueled internal combustion engine. The electric and thermal loads of a Harbin residential building in a typical winter heating week are calculated. The performance of the m-CHP systems operating in two operation strategies, i.e., Following the Electric Load (FEL) and Following the Thermal Load (FTL), are analyzed and evaluated from both energy and economic aspects. The result shows that the energy cost of the m-CHP is reduced by 10% when operating in FTL mode, and the income from selling excess energy is 2.7 times more than that in FEL mode, indicating lower operation costs in FEL mode. Moreover, compared with the traditional separate production of electricity and heat, the net cost reduction rate of the system in FEL and FTL mode is 13.68% and 38.83%, respectively. Micro-CHP operating in a district energy network is more profitable than traditional separate electricity and heat production.
