While doing some research I came upon an witter who states "you can not damage a battery by overcharging it." He meant the batteries used in Laptop Computers.
Nevertheless, the lithium ion battery is the same fundamental design that was used in the
Dream liner aircraft the FAA grounded.
Here is a recent version of the story:
https://www.scientificamerican.com/article/how-lithium-ion-batteries-grounded-the-dreamliner/Right. Scientific American. They thought the topic was worthy of more study.
At 10:21 a.m. on Jan. 7, 2013, about a minute after all 183 passengers and 11 crew members from Japan Airlines Flight 008 disembarked at Boston's Logan International Airport, a member of the cleaning crew spotted smoke in the aft cabin of the Boeing 787-8.
A mechanic then opened the aft electronic equipment bay of the plane, parked at the airport gate, and saw billowing smoke and flames coming from the batteries for the 787's auxiliary power unit (APU). He tried to use a fire extinguisher, but the blaze didn't go out.
They had a hard time controlling the fire.
The culprit was a lithium-ion battery manufactured by GS Yuasa, which was found to be under a condition known as a thermal runaway, in which the heat from a failing cell causes itself and surrounding cells to fail, thereby generating more heat.
The was enough efvgidence to blame a lot of people.
Though the aircraft are now flying again with safety retrofits, the episode highlights some of the emerging concerns around cutting-edge clean technologies, particularly those that store large amounts of energy...
Quality-control problems suspected. Last year, a spate of fires in the all-electric Tesla Model S car prompted concern among auto safety experts
