I don't know much about the technology behind these batteries so I'm wondering how they still missed the fact they were building a battery that could fail when surely the best minds in the lithium-ion battery business did all the testing they could possibly come up with? I hope the battery issue have already been addressed. I truly hope the battery problems have been fixed. One can only imagine what would happen if something even remotely similar would happen again.
Two days ago, I read an article (Discovery News) about an emerging affordable 1,000 mile aluminum-air batteries for cars. They would be a game changer if they really could be deployed. Will Lithium-Ion batteries prove too hard to control - or are we just not yet at the point of having all the necessary process controls on their production?
Same Yuasa brand, same issue with a single cell causing the problem, as was the case in the two Boeing 787 incidents, but a different flavor of Li-Ion chemistry. It will be interesting to see if the focus (finally) goes inside the cells themselves, instead of addressing peripheral, unlikely, easier to protect against, and easier-to-check-and-rule-out causes.
As appealing as Li-Ion batteries are, this thermal runaway seems to have been such a common problem that one would think the root causes by now would have been discovered and remedied?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
