electrochemical properties of various rock-shaped-cuo/graphite (g) composites and monoclinic structure cuo nanoparticles as the cathode versus a zinc plate as the anode in a 4m naoh electrolyte were elucidated by electrochemical impedance spectroscopy (eis) and chronopotentiometry (cp) in a two electrode configuration cell. various values of g 9, 16 and 28 wt% were prepared and studied as catho...

Efficient and affordable synthesis of Li+ functional ceramics is crucial for the scalable production solid electrolytes batteries. Li‐garnet Li7La3Zr2O12−d (LLZO), especially its cubic phase (cLLZO), attracts attention due to high conductivity wide electrochemical stability window. However, sintering temperatures raise concerns about cathode interface stability, costs, energy consumption manufa...

The renewable energy sources and plug-in electric vehicles (PEVs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. This paper presents modelling and control of a Building Integrated Fuel Cell and Plug-in Electric Vehicles (BIFC-PEV) in smart distribution systems. In BIFC-PEV system, conventional building elements could be replaced by sp...

We demonstrate a controlled growth of nitrogen-doped graphene layers by liquid precursor based chemical vapor deposition (CVD) technique. Nitrogen-doped graphene was grown directly on Cu current collectors and studied for its reversible Li-ion intercalation properties. Reversible discharge capacity of N-doped graphene is almost double compared to pristine graphene due to the large number of sur...

In nature, cellulose, lignocellulose and lignin are major sources of plant biomass; therefore, their recycling is indispensable for the carbon cycle. Each polymer is degraded by a variety of microorganisms which produce a battery of enzymes that work synergically. In the near future, processes that use lignocellulolytic enzymes or are based on microorganisms could lead to new, environmentally f...

times. Hippocrates in the fourth century B.C., described the illness due to working in the smelting of lead ores. With the progress of industrialization the use of lead is also increasing in some form or another. Commonly, lead is encountered in printing and pigment industries, in the manufacture of insecticides, pottery and storage battery industries and in the mining and milling of lead ore. ...

Lithium ion batteries are among the most used rechargeable batteries in the world. Carbon nanostructures including carbon nanotubes (CNTs) are considered as important electrode materials for this kind of batteries. Therefore improving the performance of these carbon based electrodes in Lithium ion batteries is an important issue and attracts much attention in the battery community. In this manu...

This paper proposes an alternating discharge method of multiple battery cells to extend battery operation time. In the proposed method, two battery cells are periodically connected in turn to a mobile device and only one cell supply power while the other rests. Battery operation time of the connecting cell decreases due to rate-capacity effect, while that of the resting cell increases due to re...
