⎯ A thermoelectric energy scavenging microsystem is proposed, optimized to convert the small thermal power available in human-body applications. A Lithium solid-state thin-film battery is integrated in the same device as well as the ultra low-power electronics to charge battery and perform DC-DC conversion.

In this paper, an extended analysis of the performance of different hybrid Rechargeable Energy Storage Systems (RESS) for use in Plug-in Hybrid Electric Vehicle (PHEV) with a series drivetrain topology is analyzed, based on simulations with three different driving cycles. The investigated hybrid energy storage topologies are an energy optimized lithium-ion battery (HE) in combination with an El...

OBJECTIVES Recent cases suggest that severe and fatal button battery ingestions are increasing and current treatment may be inadequate. The objective of this study was to identify battery ingestion outcome predictors and trends, define the urgency of intervention, and refine treatment guidelines. METHODS Data were analyzed from 3 sources: (1) National Poison Data System (56535 cases, 1985-200...

DOI: 10.1002/aenm.201600154 due to their limited specific capacity.[18,19] Very recently, we have proposed that conversion reaction materials can be attractive high capacity prelithiation materials for cathodes and demonstrated using Li2O/metal and LiF/metal nanocomposites.[20,21] For example, a high “donor” lithium-ion specific capacity of 609 mAh g−1 has been achieved for a stable nanoscaled ...

The electronic and adsorption properties of graphene can be changed significantly through substitutional doping with nitrogen and nitrogen decoration of vacancies. Here ab initio density functional theory with a dispersion correction was used to investigate the stability, magnetic and adsorption properties of nine defects in graphene, including both nitrogen substitutional doping and nitrogen d...

This paper reports on the design and operation of a flexible power source integrating a lithium ion battery and amorphous silicon solar module, optimized to supply power to a wearable health monitoring device. The battery consists of printed anode and cathode layers based on graphite and lithium cobalt oxide, respectively, on thin flexible current collectors. It displays energy density of 6.98 ...

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...
