What makes lithium ion batteries dangerous? Part 2

Подробнее о видео

What are the hazards associated with lithium-ion batteries, and how can these turn into safety risks? Last week Risk Bites looked at the bottom-line risk challenges of lithium-ion batteries. This week we take a closer look at the technology behind the batteries used in cell phones, laptops and the latest high-tech airplanes like Boeing's 787 Dreamliner.
