We quantify the effects of the duration of the charge-discharge cycling period on the irreversible loss of anode material in rechargeable lithium metal batteries. We have developed a unique quantification method for the amount of dead lithium crystals (DLCs) produced by sequences of galvanostatic charge-discharge periods of variable duration τ in a coin battery of novel design. We found that th...

New energy industry including electric vehicles and large-scale energy storage in smart grids requires energy storage systems of good safety, high reliability, high energy density and low cost. Here a coated Li metal is used as anode for an aqueous rechargeable lithium battery (ARLB) combining LiMn2O4 as cathode and 0.5 mol l(-1) Li2SO4 aqueous solution as electrolyte. Due to the "cross-over" e...

Context: Over the last ten years the ingestion of disk batteries and its serious consequences have been increasing. The severity of injury is related to a growing diffusion of the new lithium battery that may cause catastrophic damages when lodged in the esophagus in children. Case report: A five-year-old boy presented to the Emergency Department of our tertiary pediatric Institute for a lithiu...

Although the rechargeable lithium-sulfur battery is an advanced energy storage system, its practical implementation has been impeded by many issues, in particular the shuttle effect causing rapid capacity fade and low Coulombic efficiency. Herein, we report a conductive porous vanadium nitride nanoribbon/graphene composite accommodating the catholyte as the cathode of a lithium-sulfur battery. ...

This paper proposes a design of power system control in the hybrid electric vehicle. It adopts the isolated DC/DC power converter as the front-end fuel cell and Lithium-ion battery to supply constant voltage. By micro-controller to detect the hybrid power output, and the low-pressure hydrogen storage temperature, and the adjustment of the power output ratio to provide the energy for loading bal...

Lithium-sulfur (Li-S) battery has emerged as one of the most promising next-generation energy-storage systems. However, the shuttle effect greatly reduces the battery cycle life and sulfur utilization, which is great deterrent to its practical use. This paper reviews the tremendous efforts that are made to find a remedy for this problem, mostly through physical or chemical confinement of the li...

The market of grid-level electricity storage is growing rapidly, with a predicted market value of 1.6 billion in 2012 and 8.3 billion in 2016. Electrochemical storages such as lead-acid, nickel-cadmium, sodium-sulfur and lithium-ion batteries are candidates with high potential for grid-level implementations. Among them, sodium-sulfur battery appears to be suitable for energy application while l...

Li2Ni8O10 and LiMn2O4 Nanoparticles as cathode materials of lithium ion battery, were successfully synthesized using lithium acetate, nickel and manganese acetate as Li, Ni and Mn sources and stearic acid as a complexing reagent. The structure of the obtained products were characterized by FT-IR and XRD. The shape, size and distribution of the Li2Ni8O10 and LiMn2O4 nanoparticles were observed b...

Lithium-based rechargeable batteries have been widely used in portable electronics and show great promise for emerging applications in transportation and wind-solar-grid energy storage, although their safety remains a practical concern. Failures in the form of fire and explosion can be initiated by internal short circuits associated with lithium dendrite formation during cycling. Here we report...
