Abstract

A method of forming an electrochemical cell is disclosed. The method comprises contacting a negative pole layer and a positive pole layer one with the other or with an optional layer interposed therebetween. The pole layers and the optional layer therebetween are selected so as to self-form an interfacial separator layer between the pole layers upon such contacting.

Description

technical field [0001] The present invention relates to thin-layer, liquid chemical batteries, preferably of open configuration, for use as battery power sources for the conversion of chemical energy into electrical energy, and in particular to such batteries having a liquid electrolyte and an autogenous porous separator layer between positive and negative electrode layers. Background technique [0002] Batteries fall into two broad categories: liquid batteries, ie, those with a liquid or wet electrolyte, and solid-state batteries, ie, those with the electrolyte in a solid state. The advantage of solid-state batteries over liquid batteries is that they never dry out or leak. However, their main disadvantage compared to liquid batteries is that their operation is largely temperature dependent and many only function properly at high temperatures due to the limited rate of charge diffusion through the solid. Due to the limited diffusion rate, the ratio between the electrical e...
