Abstract
A battery cell comprising a composite water-responsive safety layer and/or composite water- and pH-responsive safety layer to protect against tissue damage and/or electrolysis, when the battery cell is exposed to aqueous solution or tissue, is provided.
Claims19
A battery comprising:
- a housing, the housing comprising first and second poles;
- and
- a composite water-responsive safety layer comprising a polymer material and being positioned adjacent to at least one of the first and second poles, the composite water-responsive layer being adapted to change from a non-electronically conducting state to an electronically conducting state when contacted with an aqueous solution, the safety layer further comprising at least one metal salt, the at least one metal salt comprising at least a first metal salt and a second metal salt.
