ELECTROCHEMICAL BATTERY

摘要

An electrochemical cell and a method of reducing potential hazard in electrochemical cells are provided. The cell (18) has as reactive components molten sodium (22) and molten sodium aluminium chloride (28) and according to the invention a macroporous material such as a fibrous felt material is impregnated by one of said reactive components in a zone where they can react upon damage to the cell, to reinforce the reaction products produced and to enhance the ability of the reaction product to separate the reactive components from each other, to reduce undesirable consequences of the damage.
