Energy storage devices such as rechargeable batteries make wearable devices to become more independent from power outlets, or in other words, make device portability. Battery energy density determines how long a battery powered device will work before it needs a recharge. Longer the time before battery needs recharge, better it is for device applications. Therefore, the goal of battery researchers and engineers is to develop a battery that can provide high energy density and longer device operation.

  • Thin Flexible Lithium-Ion Battery Featuring Graphite Paper Based
    169 ARTICLE Thin flexible lithium-ion battery featuring graphite paper based current collectors with enhanced conductivity Hang Qu, Jingshan Hou, Yufeng Tang, Oleg Semenikhin, and Maksim Skorobogatiy Abstract: A flexible, lightweight, and high conductivity current collector is the key element that enables fabrication of a high-performance, flexible lithium-ion battery. Here, we report a thin, lightweight, and flexible lithium-ion battery that uses graphite papers deposited with nano-sized metallic layers as the current collector, LiFePO4 and Li4Ti5O12 as the cathode and anode materials, respectively, and a PE membrane soaked in LiPF6 as the separator. Using thin, flexible graphite paper as a substrate for the current collector instead of a rigid, heavy metal foil enables us to demonstrate an ultra-thin lithium-ion battery (total thickness including encapsulation layers of less than 250 ␮m) that also features a light weight and high flexibility. Key words: lithium-ion batteries, flexible batteries, graphite paper current collectors. Résumé : Un collecteur de courant a` conductivité élevée, a` la fois flexible et léger, constitue un élément clé pour permettre la fabrication d’une batterie au lithium-ion flexible a` haut rendement. Dans le présent article, nous rapportons la fabrication d’une batterie au lithium-ion mince, flexible et légère constituée de collecteurs de courant faits de feuilles de graphite déposées sur des nanocouches métalliques, d’une électrode composée d’une cathode de LiFePO4 et d’une anode de Li4Ti5O12, et d’un séparateur consistant en une membrane imbibée de LiPF6. L’utilisation d’une feuille de graphite flexible comme substrat du collecteur de courant au lieu d’une feuille métallique lourde et rigide nous permet de démontrer la réalisation d’une batterie au lithium-ion ultramince (épaisseur totale comprenant des couches d’encapsulation de moins de 250 ␮m) qui présente également un faible poids et une grande flexibilité.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE > REPLACE THIS LINE WITH YOUR PAPER IDENTIFICATION NUMBER (DOUBLE-CLICK HEREprovided TO EDIT) by University < of Liverpool1 Repository MMC-Based SRM Drives with Decentralized Battery Energy Storage System for Hybrid Electric Vehicles Chun Gan, Member, IEEE, Qingguo Sun, Jianhua Wu, Wubin Kong, Member, IEEE, Cenwei Shi, Member, IEEE, and Yihua Hu, Senior Member, IEEE Abstract—This paper proposes a modular multilevel converter (MMC)-based switched reluctance motor (SRM) drive with decentralized battery energy storage system (BESS) for hybrid electric vehicle (HEV) applications. In the proposed drive, a battery cell and a half- bridge converter is connected as a submodule (SM), and multiple SMs are connected together for the MMC. The modular full-bridge converter is employed to drive the motor. Flexible charging and discharging functions for each SM are obtained by controlling switches in SMs. Multiple working modes and functions are achieved. Compared to conventional and existing SRM drives, there are several advantages for the proposed topology. A lower dc bus voltage can be flexibly achieved by selecting SM operation states, which can dramatically reduce the voltage stress on the switches. Multilevel phase voltage is obtained to improve the torque capability. Battery state-of-charge (SOC) balance can be achieved by independently controlling each SM. Flexible fault-tolerance ability for battery cells is equipped. The battery can be flexibly charged in both running and standstill conditions. Furthermore, completely modular structure is achieved by using standard half-bridge modules, which is beneficial for market mass production.

  • "Advanced Battery Development"
    Issue 69 FEV CUSTOMER MAGAZINE CUSTOMER MAGAZINE CUSTOMER "ADVANCED BATTERY DEVELOPMENT" Strong Partner for Battery Development FEV Battery Benchmarking Batteries from a Single Source eDLP – World's largest development and Issue 69 test center for high- voltage batteries Dear Readers, Due to the increasing electrification of vehicle fleets to reduce CO2 and pollutant emissions, batteries for energy storage are a decisive factor for success. This applies not only to the automotive sector, but also to (smaller) commercial vehicle, industrial and marine applications. What all applications have in common is the high development effort for FEV’s partners. In this issue of SPECTRUM, we would like to give you an overview of the competencies FEV can offer to support you in meeting the challenges in this context – from the battery concept to production readiness and beyond, including recycling. In addition to pure battery development, we also address special aspects such as precise monitoring by battery management sys- tems. Furthermore, we present our benchmarking offerings and demonstrate our expertise in battery assembly. Finally, we outline characteristics that arise for the testing of electrified drives and batteries. In a dedicated article on battery testing, we also present the new development and test center for high-voltage energy storage (eDLP) in Sandersdorf-Brehna, Germany, which is the largest facility of its kind in the world. The commissioning of the eDLP will be finalized in the third quarter of this year and will enable FEV to offer all internationally required test methods for high-voltage batteries from the cell to the module to the pack, all at one location.

Abstract: A flexible, light weight and high conductivity current collector is the key element that enables fabrication of high performance flexible lithium ion battery. Here we report a thin, light weight and flexible lithium ion battery that uses graphite paper enhanced with a nano-sized metallic layers as the current collector, LiFePO4 and Li4Ti5O12 as the cathode and anode materials, and PE membrane soaked in LiPF6 as a separator. Using thin and flexible graphite paper as a substrate for the current collector instead of a rigid and heavy metal foil enables us to demonstrate a very thin Lithium- Ion Battery into ultra-thin (total thickness including encapsulation layers of less than 250 μm) that is also light weight and highly flexible. 1 Introduction Many wearable and portable electronic devices require efficient, compliant power sources that can fully function when bent, folded, or compressed. 1 Lithium-ion batteries (LIBs) dominate the portable power-source market due to their high energy density, high output voltage, long-term stability and environmentally friendly operation. 1, 2, 3 High performance flexible LIBs are considered to be one of the most promising candidates of the power sources for the next generation flexible electronic devices.
