Tin–Transition Metal–Carbon Systems for Lithium-Ion Battery Negative Electrodes

Si1-xBx thin films of 0.071 ≤ x ≤ 0.950 have been synthesized using combinational sputtering. All Si1-xBx film compositions had a highly amorphous structure consisting of amorphous Si and B phases, as characterized by X-ray diffraction. In Li cells, it was found that all of the Si is active and the B is inactive with lithium. Otherwise, the Si1-xBx films have similar characteristics as pure Si film electrodes in Li cells, except with reduced capacity due to the added B. However, shifts in the voltage curves appear when the B content is increased that may be induced by stress-voltage coupling between the active Si and the inactive B phases.

“…Substantial problems in actual application result from the significant shape change of tin electrodes during charging and discharging [69]. Attempts have been reported to meet this challenge by preparing nanosized particles [70] or by incorporating tin (or its oxide SnO 2 ) in suitable host structures [71,[72][73][74][75][76].…”

Abstract. The basic concepts of electrodes and electrochemical cells (including both galvanic and electrolytic ones) are introduced and illustrated with practical examples. Particular attention is paid to negative electrodes in primary and secondary cells, fuel cell electrodes and electrodes in redox flow batteries. General features and arguments pertaining to selection, optimization and further development are highlighted.

Printed on paper containing at least 50% wastepaper, including 10% post consumer waste. ForewordIn 2010, the National Renewable Energy Laboratory (NREL) entered into a subcontract agreement with Dr. Daniel Doughty, the principal of Battery Safety Consulting Inc. At NREL, we perform battery research and development (R&D) in areas of materials, modeling, testing, and system analysis, particularly as they relate to the lithium-ion (Li-ion) battery safety modeling and testing for electrified vehicles. This work was supported by the U.S. Department of Energy's (DOE) Energy Storage R&D Vehicle Technologies Program in the Office of Energy Efficiency and Renewable Energy under DOE/VTP Agreement 16378 of the 1102000 B&R, NREL Task Number FC086200.The purpose of the subcontract was to investigate the research, development, and other activities related to the safety of Li-ion batteries for electric drive vehicles and to provide recommendations for developing a DOE roadmap for the safety of Li-ion batteries for electric drive vehicles. Dr. Doughty has a long, distinguished career in battery R&D, particularly at Sandia National Laboratories (SNL), where he was responsible for the safety and abuse tolerance testing of batteries for more than 15 years. Dr. Doughty has chaired the Society of Automotive Engineers (SAE) committee that revised and updated SAE Recommended Test Procedure J2464, "Electric and Hybrid Electric Vehicle Rechargeable Energy Storage System (RESS) Safety and Abuse Testing," published November 2009. With his strong experience in battery safety and involvement with safety committees, Dr. Doughty was in a unique position to perform this work by collecting the necessary information, interacting with key players in the community, and providing recommendations.This document is divided into two sections: (1) the synopsis, which discusses high-level findings of the work, and (2) the full report, which provides a comprehensive, in-depth review of the state of the art and also discusses interactions with experts, users, researchers, and developers from different organizations interested in the safety of vehicle batteries.The findings and recommendations in this document will be taken into consideration by the Energy Storage R&D Program at the DOE Vehicle Technologies Program for further defining the R&D roadmap for developing safer batteries for electric drive vehicles. SynopsisThe safety of electrified vehicles with high-capacity energy storage devices creates challenges that must be met to ensure commercial acceptance of electric vehicles (EVs) and hybrid electric vehicles (HEVs). One of the most important objectives of DOE's Office of Vehicle Technologies is to support the development of Li-ion batteries that are safe and abuse tolerant in electric drive vehicles.Batteries for EVs and HEVs, which in this document includes plug-in hybrid electric vehicles (PHEVs), are different from batteries developed for other applications. The environment that vehicle traction batteries experience during their life is more diff...
