The impact of lithium-metal-polymer battery characteristics on telecom power system design

Abstract: AVESTOR's lithium-metal-polymer (LMP) technology is an advanced battery system for stationary and automotive applications Papers have been presented at Intelec in past years on this technology, focusing on basics of the electrochemistry, key benefits and field test results The present paper will describe the electrochemical system in greater detail, outline the subsystems that optimize the operation of the battery and show their impact on telecommunication applications The lithium-metal-polymer battery utilizes an electrochemical configuration composed of a metallic lithium anode, a simple copolymer based on polyether chemistry, vanadium oxide and a lithium salt, lithium bistrifluoromethanesulfonamide (LiTFSI) What are the specifics of the LMP electrochemistry and how does it influence the properties and performance of the battery? This paper will answer these questions by describing and explaining the electrochemistry and the resulting properties of the electrochemical cell To optimize the battery performance, certain conditions are required and are achieved by control subsystems integrated into the battery This paper will explain these main subsystems, their function and their influence on operation and performance Finally, this paper will describe how the electrochemistry and its integrated subsystems affect the installation and operation of LMP batteries in telecommunication applications from an end-user perspective

High Power Organic Radical Battery for Information Systems

Abstract: We have developed a high-power organic radical battery for information technology equipment such as personal computers (PCs). The battery provides several minutes of backup power without an external uninterrupted power source. Since the built-in battery makes energy conversion from AC to DC, or DC to AC, unnecessary, it protects equipment from power failure with no loss of energy. The fabricated battery shows a high power density of 1 kW/L and is capable of driving a desktop PC for several minutes. The use of purely organic polyradicals, poly (2,2,6,6-tetramethylpiperidinyloxy mathacrylate), for the cathode active material opens up a new field of high power density, environmentally friendly batteries.

Recent Development of Lithium Ion Batteries

Abstract: Lithium ion batteries are much welcomed by consumers and have found wide application in mobile phones, notebook computers and other portable electrical appliances They have potential application in the future electrical vehicle and will have a deep influence on the way of people's life The capacity and cycling performance of lithium ion batteries have improved a lot New kinds of batteries with higher capacity, lighter weight, smaller volume and lower cost are continually put into market New electrode materials and electrolytes with high capacity, low cost, non-toxicity, and safety are developed The historical and recent development of cathodes, anode materials and electrolytes are reviewed in this paper

Lead-acid battery having an organic polymer additive and process of charging thereof

Abstract: A process for prolonging the life of a lead-acid battery by adding an organic polymer and ultra fine lignin to its electrolyte and then discharging the battery at a high current rate and the battery so produced.
