Boeing lithium ion battery

Do Boeing 787s have lithium-ion batteries?

Boeing was required to demonstrate that the 787s design complied with the Federal Aviation Administration's (FAA) Special Conditions 25-359-SC, Boeing Model 787-8 Airplane; Lithium-Ion Battery Installation, which detailed nine specific requirements regarding the use of these batteries on the airplane.

What chemistry does Boeing use for lithium ion batteries?

When Boeing was initially qualifying the design of their battery system in 2009, lithium cobalt oxide (LiCoO 2) was the most widely used cathode chemistry for most commercial lithium-ion battery applications. This was due to its high energy density and high voltage limit compared to alternative chemistries.

Why do Boeing 787 Dreamliners use lithium-ion batteries?

The lithium-ion batteries used in Boeing's 787 Dreamliner are central to the design of a plane which is billed as being lighter and 20% more fuel efficient than earlier generations of jet.

Why do aircraft use lithium-ion batteries?

Other aircraft makers have also been using more lithium ion batteries. In addition to being light and packing lots of power, lithium ion batteries also require less maintenance. There's no need to fully drain the battery before recharging, as was the case with older nickel cadmium batteries.

What is lithium ion battery technology?

Lithium-ion battery technology was chosen for its high energy density and long cycle life compared to other battery chemistries. Lithium-ion batteries operate by shuttling lithium ions between two electrodes to transfer charge and generate current.

What are the advantages of lithium ion batteries?

In addition to being light and packing lots of power, lithium ion batteries also require less maintenance. There's no need to fully drain the battery before recharging, as was the case with older nickel cadmium batteries. Plus, they may be less environmentally toxic during disposal.
