Li Ion Battery Safety and Abuse Tolerance Report

Safety concerns arise when batteries are abused, used outside the design’s operational space, poorly designed, or beyond useful life. Heat generation and gas generation are the most common responses of batteries to abusive conditions--the most serious consequences occur when the stored energy is rapidly released in an unintended manner, triggering thermal runaway. This report presents the fundamentals of battery safety and abuse tolerance. It discusses materials, cells, and battery system design, manufacturing, applications, and validation, as well as the lessons learned from recent failures.

Dr. Daniel Doughty,
President, Battery Safety Consulting, Inc.
Dr. Doughty founded his consulting firm in 2008 to provide independent expert consulting services for a wide range of battery safety issues, including failure analysis, test method development, interpretation of test results, expert witness and forensic consulting. In this capacity, he works with battery developers and integrators to secure and validate battery system safety under all foreseeable abuse conditions; he also assists standard and test organizations in establishing battery safety test standards.

Dr Doughty’s many accomplishments include:

• Chair of the SAE J2464 Committee that re-wrote and improved Society of Automotive Engineers Recommended Test Procedure J2464 “Electric and Hybrid Electric Vehicle Rechargeable Energy Storage System (RESS) Safety and Abuse Testing”; published November 2009.
• Authored the handbook entitled "Vehicle Battery Safety Roadmap Guidance" (Oct. 2012) which provides guidance to DOE Office of Vehicle Technologies' R&D program to improve electric vehicle safety.
• Established and managed the premier US battery safety testing facility while leading the Advanced Power Source R&D department of Sandia National Laboratories between 1992 and 2006.
• Wrote the Battery Abuse Test Standard that was accepted by US Advanced Battery Consortium (USABC) for safety evaluation of hybrid vehicle batteries in 2005
• Principal Investigator for NHTSA's "Safety Performance of Rechargeable Energy Storage Systems" Program to improve xEV battery safety tests, March 2013 to September 2014.
• Provided expert testimony to NTSB Panel regarding Boeing 787 Battery Fire Investigation, 11 April 2013.
• Author of book chapters, “Rechargeable Lithium Batteries (Ambient Temperature)” in 4th Edition of Linden’s Handbook of Batteries, T. B. Reddy, Ed. (2011, McGraw-Hill) and “Battery Safety and Abuse Tolerance” in Handbook of Battery Materials, Claus Daniel, Ed. (2011,Wiley-VCH)
• Performed pioneer work on the safety of Lithium Sulphur batteries while serving as Vice President at Sion Power Corporation between 2006 and 2009.
