ELECTROCHEMICAL CELLS HAVING A GELLED ANODE-ELECTROLYTE MIXTURE |
摘要 |
An electrochemical cell having an anode, a cathode and an aqueous alkaline electrolyte solution. The anode is an intimate gelled mixture of a powdered metal, an aqueous electrolyte solution and an agent capable of gelling the mixture. The agent is a material capable of absorbing water and having a carbohydrate backbone which has a water soluble side chain grafted thereon. A preferred agent is a water insoluble salt of an aqueous alkali saponified gelatinized starch having a water soluble side chain grafted thereon. The gelling of the intimate mixture of the powdered metal anode and electrolyte solution with the agent is a method of improving the discharge characteristics of the cell. |
