In order to reduce the amount of inactive materials, such as binders and carbon additives in battery electrode, porous cobalt monoxide nanofibers were directly grown on conductive substrate as a binder/additive-free lithium-ion battery anode. This electrode exhibited very high specific discharging/charging capacities at various rates and good cycling stability. It was promising as high capacity...

A class of imprintable, bendable, and shape-conformable polymer electrolyte with excellent electrochemical performance in a lithium battery system is reported. The material consists of a UV-cured polymer matrix, high-boiling point liquid electrolyte, and Al2 O3 nanoparticles, formulated for use in lithium-ion batteries with 3D-structured electrodes or flexible characteristics. The unique struct...

We present an incisive spectroscopic technique for directly probing redox orbitals based on bulk electron momentum density measurements via high-resolution x-ray Compton scattering. Application of our method to spinel Li_{x}Mn_{2}O_{4}, a lithium ion battery cathode material, is discussed. The orbital involved in the lithium insertion and extraction process is shown to mainly be the oxygen 2p o...

The electrochemical performance characteristics of a prismatic lithium-ion battery, ultracapacitors, and hybrid combinations at ambient temperature are considered. The effects of pulse current, duty cycle and hybrid combinations are studied. Current pulsing was shown to improved the total energy discharged from the lithium-ion battery and battery / capacitor hybrid combinations over that of a c...

The Peukert relationship was originally introduced in 1897 for lead-acid batteries and defines one of the most common parameters for battery performance evaluation. This article assesses its application for lithium-ion batteries. From the performed analysis, we can conclude that the Peukert relationship is suitable in a narrow working range such as limited current range and almost constant work...

Introduction With the goal of promoting energy conservation and exploring forms of energy alternative to petrified sources, as well as of reducing environmental burden, much effort has been spent on developing new breeds of vehicles. These include Hybrid vehicles (HV) that run on a combined system of a fossil fuel engine and an electric motor, Plug-in HVs (PHVs) that allow recharging of the in-...

The lithium ion batteries, thanks to their high densities and high power, became promotes element for hybrid-electric and plug-in electric vehicles. Thermal management of lithium ion battery is important for many reasons, including thermal runaway, performance and maintains a constant temperature during the operating, security, lifecycle. However, in a battery pack, the batteries are stacked ag...

As an alternative to pure lithium-ion, Li+, systems, a hybrid magnesium, Mg2+, and Li+ battery can potentially combine the high capacity, high voltage, and fast Li+ intercalation of Li-ion battery cathodes and the high capacity, low cost, and dendrite-free Mg metal anodes. Herein, we report on the use of two-dimensional titanium carbide, Ti3C2Tx (MXene), as a cathode in hybrid Mg2+/Li+ batterie...

A novel lithium ion sulfur battery is formed by coupling an activated ordered mesoporous carbon-sulfur (AOMC-S) cathode and a nanostructured tin-carbon anode. The lithium ion cell has improved reversibility, high energy content and excellent cycle life.

Room temperature ionic liquids are considered as potential electrolytes for high performance and safe lithium batteries due to their very low vapor pressure and relatively wide electrochemical and thermal stability windows. Unlike organic electrolytes, ionic liquid electrolytes are molten salts at room temperature with dissociated cations and anions. These dissociated ions interfere with the tr...
