slimed battery / Semipermeable membrane deforma

Battery uses carbon rod suppression absorption design, the electrolysis product is difficult to enter the inner conductor resistance increases caused by battery ,convient to make full use of electricity.Waste gas generated by the reaction can be discharged through the polymer film in unidirectional way,which can make a paste with the discharge electrolysis deformation occurs, but also easy to determine the remaining power and remove the used batteries.
