Self-destruct battery completely dissolved in water for 30 minutes

Scientists at Iowa State University developed a lithium-ion battery which fully decomposes after use.
Саморазрушающийся аккумулятор
 
The presented sample is intended for powering an electronic device for 15 minutes. Used battery dissolves within 30 minutes after immersion in water.
 
Eight-layer miniature battery including an anode, a cathode, and an electrolyte dissolves completely after use, thanks to the alcohol-containing polymer. Nanoparticles not capable of decomposing disperse to the environment and do not pose a threat.
 
These power supplies are planned to be embedded in implants unrecoverable from the patient's body, because after the establishment of a resource they will dissolve without harming the body. Also, self-destruct batteries will be indispensable in a variety of electronic devices with a limited time of use.
 
Disposal of spent batteries and accumulators requires significant material costs, and the use of self-destruct batteries allows cutting them. This development will allow finding a compromise between the time of the source's power, its capacity and environmental safety.
