Abstract:
An electrochemical device is disclosed and may include an electrolyte composition disposed between the anode and the cathode and a water vapor barrier which may include a biodegradable material, where the water vapor barrier is disposed to prevent water vapor escaping from the electrochemical device. The water vapor barrier further may include poly lactic acid or a metalized coating. The water vapor barrier further may further include multiple layers and have a water vapor transmission rate (WVTR) less than or equal to 2 wt % over 24 hours. Embodiments of the water vapor barrier may also include a polymeric biodegradable material or a metalized coating disposed onto the biodegradable material. The water vapor barrier may also include multiple layers and may have a water vapor transmission rate (WVTR) less than or equal to 1 mg per cm2 over 24 hours.
