Batteries are playing more crucial roles, both helpful and hazardous, in the daily lives of humans. With use and technology growing rapidly in lithium batteries, dramatic accidents are happening, due largely to human error. Urban areas rife with electric delivery bikes are reporting fires and even resulting deaths from the improper charging methods of scooter and e-bike lithium batteries. Automobile accidents involving electric cars create stories of certain death and a fiery grave for the victims, whose remains are sometimes unrecoverable.

But there are positive reports of household battery use in safer conditions. Suburban owners are running their household on batteries that have been charged in the wee hours when utility rates are at their lowest. Certain rural municipalities are building massive storage units the size of football fields to relieve strain on their grid. New battery technology is making this possible.
