Request Expert

Expert has a great deal of experience in failure analysis of various battery systems including lithium, lithium-ion, lithium-polymer, and various other nonaqueous and aqueous based systems, both primary and secondary. He is the sole battery safety instructor for NASA and has also taught a battery applications class with the director of R&D from a major battery company to NASA. Through his over 40 year career in high reliability lithium, lithium-ion, and aqueous batteries he has designed, built and tested batteries for heart pacemakers, satellites, and remote applications and environments where the batteries can not be replaced. He has worked with numerous chemical systems including; lithium-iodine, lithium-CFx, lithium-manganese dioxide, various lithium-liquid cathode systems, lithium-ion, lithium-polymer, sodium-sulfur, nickel-hydrogen, nickel-metal hydride, nickel-cadmium, silver-zinc, lead-acid, alkaline, and thermal batteries. He has his own facility for battery testing and battery teardown for failure analysis of battery systems and has done so for NASA, the aerospace community, and various commercial vendors, as well as, the legal community.

Prior to starting his own business over 20 years ago he also acted as an in house consultant for major corporations due to his broad knowledge in battery applications both in military/government and the commercial sectors. At his test facility he has performed life, characterization, and safety testing for NASA and other customers and has equipment capable of wide temperature, current, and voltage ranges. He has qualified batteries for both the STS (shuttle) and the ISS (International Space Station). The safety test chamber can safely test batteries up to approximately one kW. Expert has a battery database that goes back more than 40 years which has been useful for some legal actions on patent infringement and where replacement batteries are no longer available. He is an expert in "system design" which is a requirement to obtain high reliability and long life in remote applications and modern devices.

He has a thorough understanding of the battery interfaces and their effect on the lifetime of the battery. These interfaces include; thermal, electrical, and mechanical, as well as, the internals of the cell and battery designs and the quality control necessary to obtain these goals. He has performed trouble shooting and failure analysis for such organizations as NATO and has helped commercial customers which has had reporting requirements to the FAA and FDA. He has reviewed contracts for the DoE and other government organizations. He has presented numerous papers and has been an invited speaker to the Inorganic Fluorine Chemistry meeting in Russia.

He has previously been involved with automobile racing as pit crew and technical inspector and has served on an ad hoc committee for EV racing for the Sports Car Club of America. Expert has also built prototype batteries for both military and commercial customers, as well as, performed international marketing and analysis.

He determined the reason for failure and fire of a lithium-ion battery system aboard a racing catamaran sailboat.He determined the reasons for failure in lithium-ion batteries in a portable gaming device, PDA, cell phone, and digital cameras.He has been responsible for determining battery failures on numerous battery designs for both military and commercial customers and has provided support for new programs that required specialty batteries.He has provided battery testing and consulting services for various customers in the aerospace industry for both aircraft and space applications. He has his own battery testing and disassembly and analysis facility.He has performed trouble shooting and design considerations for various government customers.

Expert may consult nationally and internationally, and is also local to the following cities: Spokane, Washington
