Scientists have developed a stretchable, elastic, self-healing hydrogel battery that lacks the toxic components and moisture problems that have previously plagued similar products. The researchers demonstrated its strength by cutting, puncturing, and vigorously twisting it.
Conventional soft lithium-ion (Li-ion) batteries suffer from performance degradation caused by moisture ingress. They also pose potential safety risks due to toxic, flammable electrolytes, scientists have noted.
To address these shortcomings, the researchers developed an electrolyte based on a fluorine-free lithium salt. They reported their findings in a study published April 9 in the journal Science Advances.
