787 Battery
Include what you BELIEVE really caused the problem:
During battery operation, lithium at the negative electrode gives up electrons to become Li+, which dissolves into the electrolyte. This process is reversed during the recharge cycle, but the replated lithium adds unevenly to the electrode surface, and as the battery is charged and discharged, dendrites grow from the surface, which can cause short-circuiting in the battery and lead to explosions.
REALLY caused the problem:
Most of the batteries will pass all tests. During the manufacturing of the cells the annealing process has to be monitored Microscopically. Contamination or lack of proper cooling creates a Dendritic Structure.
And what can be done to prevent a recurrence:
Quality Control. Environment in manufacturing process.
OR correct the situation:
Work together!
