Why do you think Boeing picked the lithium-ion battery?
Boeing chose the design that it says best met the needs of the 787, including all federal and international safety standards. “We chose the lithium-ion battery because it was superior in performance to other battery technology at the time,” Boeing 787 Chief Engineer Mike Sinnett told accident investigators.
Is the 787 a failure?
Current 787 deliveries have been mostly suspended over the last year because of quality control programs involving microscopic tolerances of fasteners joining fuselage barrels together, and additional issues with electrical systems and windscreens. This has resulted in around 100 undelivered 787s subject to rework.
How long was the Dreamliner grounded?
The Dreamliner, Boeing’s marquee wide-body jet, experienced a series of early teething problems that caused it to enter the market more than three years late in 2011. Regulators grounded the aircraft for three months in early 2013 after two lithium-ion batteries incinerated.

Who makes nickel cadmium batteries?
SAFT Corporation
The abbreviation NiCad is a registered trademark of SAFT Corporation, although this brand name is commonly used to describe all nickel-cadmium batteries. The abbreviation NiCd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd). There are two types of NiCd batteries: sealed and vented.
Why lithium batteries can catch on fire but last longer and provide more power than the older cadmium and nickel batteries?
It was these same batteries that caught fire in laptops a few years back and, more recently, were suspected culprits in electric car fires.Why they’re better: Lithium is the lightest of all metals, so its ions hold energy more efficiently — more than twice as much per unit of weight as nickel cadmium batteries.
