AI Technical Summary
Technical Problem
Small consumer batteries, particularly coin-cell batteries, pose a risk of tissue damage and electrolysis if swallowed, especially by infants and pets, due to the chemical reaction with bodily fluids, leading to electrolysis and combustion.
Method used
A battery with a safety mechanism that includes a housing with first and second electrodes and spacers made of electronically insulating material, which undergo physical changes in the presence of aqueous solutions to short-circuit the battery, reducing the voltage below harmful levels.
Benefits of technology
The safety mechanism effectively prevents tissue damage and electrolysis by short-circuiting the battery when exposed to moist tissue, reducing the cell voltage to safe levels, thereby preventing harmful reactions.

Abstract
The present invention provides a battery with a safety mechanism that protects the battery from tissue damage and / or electrolysis when exposed to aqueous solutions or wet tissue. [Solution] The battery 50 comprises a housing having first and second poles. At least one electron conductor 66 is electronically coupled to one of the first and second poles. A spacer 64 made of an electronic insulating material is provided between the electron conductor 66 and the other of the first and second poles to prevent electronic coupling between the electron conductor 66 and the other of the first and second poles. The spacer 64 can undergo physical modification in the presence of an aqueous solution so that electronic coupling between the electron conductor 66 and the other of the first and second poles may occur.
