On April 11, the Federal Aviation Administration (FAA) and the Pipeline and Hazardous Materials Safety Administration (PHMSA) said they anticipate increased use of lithium-ion batteries in transportation uses in addition to increased transport of these batteries for other purposes. Speaking at a National Transportation Safety Board (NTSB) forum, officials urged the creation of a good regulatory scheme in order to ensure safety. These batteries account for upwards of 80 percent of air cargo, and the officials anticipate demand for lithium-ion batteries will rise. NTSB officials said that while the lithium-ion batteries produce more energy in an efficient manner compared to older batteries, these batteries do pose a risk.
