Toshiba IR Day 2019 Battery Division Masayasu Toyohara Corporate Executive Vice President Toshiba Corporation November 14th, 2019 © 2019 Toshiba Corporation Forward-looking Statements This presentation contains forward-looking statements concerning future plans, strategies, and the performance of Toshiba Group. These statements are not historical facts; rather, they are based on assumptions and judgments formed by the management of Toshiba Group in light of currently available information. They include items that have not been finally decided at this point and future plans that are yet to be confirmed or that require further consideration. Since Toshiba Group promotes business in various market environments in many countries and regions, its activities are subject to a number of risks and uncertainties that are, without limitation, related to economic conditions, worldwide mega-competition in the electronics business, customer demand, foreign currency exchange rates, tax rules, regulations, geopolitical risk, natural disasters and other factors. Toshiba therefore wishes to caution readers that actual results might differ from expectations. Please refer to the annual securities report (Yuukashoken houkokusho) for FY2018 and the quarterly securities report (shihanki houkokusho) for the second quarter of FY2019 (both issued in Japanese only) for detailed information on Toshiba Group’s business risk. Toshiba’s fiscal year (FY) runs from April 1 to March 31. All figures are consolidated totals for 12 months, unless otherwise stated. Results in segments have been reclassified to reflect the current organizational structure, unless otherwise stated. © 20XX Toshiba XXX Corporation 2 Contents 01 SCiB™ Characteristics and Target Areas 02 Progress of Business 03 Promoting New Businesses Initiatives 3 © 2019 Toshiba Corporation 01 SCiB™ Characteristics and Target Areas © 2019 Toshiba Corporation 4 2019 Nobel Prize in Chemistry for Development of Lithium-ion Batteries Congratulation to John Goodenough, Stanley Whittingham and Akira Yoshino Koichi Mizushima, an executive fellow at Toshiba, while a researcher at SCiB™ Characteristics Oxford University in England working with Professor John Goodenough, discovered lithium cobalt oxide (LCO), which is used for the cathode. This discovery played a central role in the development of lithium-ion battery electrodes. K. Mizushima & et al., Mat. Res. Bull., Vol.15, pp.783-789(1980) Toshiba has developed an original battery, the SCiB™, that has a lithium titanium oxide (LTO) negative electrode. Its superior characteristics include safe operation, long life, high input and output, rapid charging, and low-temperature operation. 5 © 2019 Toshiba Corporation Differences Between SCiB™ and Other Lithium Batteries Using LTO as the anode electrode allows SCiB™ to overcome the disadvantages of conventional lithium-ion batteries.
