Energizer has introduced a new range of lithium coin batteries called Ultimate Child Shield, available in 2032, 2025, and 2016 formats. According to the company, they are the first to eliminate the risk of burns if a child swallows them. The danger arises when the battery lodges in the esophagus and saliva generates a current that triggers chemical reactions, causing severe alkaline burns within hours.
The technical mechanism behind the protection 🔬
The innovation focuses on a patented coating that interrupts the electrical circuit upon contact with saliva. Normally, a battery stuck in the esophagus generates voltage between its poles, breaking down water into sodium hydroxide. This chemical process causes damage to soft tissues in less than two hours. Energizer's safety layer acts as an insulator, preventing the ionic conduction necessary for the reaction. The technology does not alter battery performance in its conventional uses.
The ingenuity of not trusting that children won't eat your batteries 😅
Finally, someone realizes that placing shiny, round objects within a child's reach is not the best idea in the world. Until now, the strategy was to pray that the battery would pass through or trust that the little one wouldn't imitate a slot-machine robot. Energizer, with its protective layer, assumes that kids are disaster magnets and prefers to avoid the urgency of having to fish a battery out of the esophagus with forceps. A more sensible solution than blaming the child.
