Heterogeneous nanostructures may offer better or new properties that are not originally present in constituting components by judiciously combining two or more different materials. For example, silicon coating on carbon nanotubes (CNTs) improves the thermal stability of carbon nanotubes by acting as a protective fi lm, [ 1 ] and silicon-coated CNT composites have been proposed as promising lith...
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...
A cubic spline regression model was used to fit the experimental open-circuit potential ~OCP! curves of two intercalation electrodes of a lithium-ion battery. All the details of an OCP curve were accurately predicted by the resulting model. The number of regression intervals used to fit an OCP curve was determined in a way such that in each regression interval the OCP exhibits a profile predict...
Long term prediction such as multi-step time series prediction is a challenging prognostics problem. This paper proposes an improved AR time series model called ND-AR model (Nonlinear Degradation AutoRegression) for Remaining Useful Life (RUL) estimation of lithium-ion batteries. The nonlinear degradation feature of the lithiumion battery capacity degradation is analyzed and then the non-linear...

Estimating the state of charge is important for any battery operated device. In case of automobile batteries, which are designed to deliver large power, many methods such as open circuit voltage based, ampere hour counting based, impedance based are used for calculating the state of charge. Internal resistance of a battery at a particular temperature directly gives the information about the sta...
It is an essential task of battery management system (BMS) to online estimate the State of Charge (SoC) of a Lithium-ion (Li-ion) battery, an important indicator of the remaining charge in the battery. Accurate modeling of the electrical behavior of a Li-ion battery can provide an accurate approximation of the battery dynamic characteristics during charging/discharging and relaxation phases. Th...
Abstract Lithium ion battery (LIB) technology is the state-of-the-art rechargeable energy storage for electric vehicles, stationary and personal electronics. However, a wide variety of degradation effects still contribute to performance limitations. The metallic copper aluminium current collectors in an LIB can be subject dissolution or other reactions with electrolytes. Corrosion these metal f...
Although the energy densities of batteries continue to increase, safety problems (for example, fires and explosions) associated with the use of highly flammable liquid organic electrolytes remain a big issue, significantly hindering further practical applications of the next generation of high-energy batteries. We have fabricated a novel "smart" nonwoven electrospun separator with thermal-trigg...
