Battery Maker to Open New Plant
Originated by Dr. Sumner P. "Shep" Wolsky and Dr. Nicola Marincic, the International Battery Seminar and Exhibit is now organized by Dr. Wolsky and Dr. A. Harry Taylor and administered by Tom DeVita. Concurrently, the 12th International Battery Materials Recycling Seminar was held at the same location.
The Battery Seminar was highly successful with presentations on a variety of timely topics and more than 450 attendees, 40 exhibitors and five additional sponsors. It opened with two tutorials.
The first was given by Yoshio Nishi of The Sony Research Center and was entitled The Past and the Present of Lithium-ion Secondary Batteries and What Lies Ahead. Nishi reviewed the history of battery technology from ancient times to the present and why, out of a possible 110 million combinations of active materials, only about 30 are currently available. Nishi also reviewed the development of lithium-ion battery technology from the introduction of the first 1.1Ah 18650 cell using lithium cobalt oxide (LCO) and coke in 1991 to the present 2.6Ah cells employing LCO and graphite anodes.
New cathode and anode materials were discussed, including the use of a Sn-Co-C alloy in Sony's Nexelion cells. The increase in safety-related recalls as cell capacity has increased was pointed out and factors affecting safety were reviewed in detail. The development of lithium-polymer batteries (LPB) was discussed and the need for gel electrolytes with a low vapor pressure was emphasized. The emergence of direct methanol fuel cells (DMFCs) as a competitor for lithium-ion and the advantages of hybrid fuel cell-battery systems were pointed out. . . . continues
