Boeing Co. is proposing several changes to the battery on its 787 Dreamliner. Here's a closer look at its plans, which still require government approval:

— Non-conducting tape wrapped around each of the eight cells that make up a battery

— Heat-resisting insulation for wiring

— Glass laminate plates between the cells and aluminum case

— Locking nuts on the metal plates that connect each cell

— New tests on each battery cell, and on the assembled battery

— New sealed steel box to house the battery

— Titanium tube to take gases from an overheated battery straight outside through a new hole in the plane
