Cathodically protected battery having sacrificial anode

摘要

A cathodically protected battery comprising a battery cell (110) having positive (160) and negative (140) electrical terminals. A sacrificial anode (150) is electrically coupled to the battery cell and situated on an external surface (120) of the battery cell. The sacrificial anode is strategically located so as to be exposed to the corrosive environment, thereby negating the corrosion of the battery electrical terminals. A plurality of cells is also configured to form a cathodically protected multicell battery package for use in a corrosive environment. The multicell battery (200) comprises a battery housing (210) and a plurality of cells (250-300) within the housing. The cells are electrically coupled together so as to terminate in a positive and a negative terminal. Electrical contacts (221 and 222) are provided on the exterior (220) of the battery housing and the positive and negative terminals of the cells are connected to these contacts. A sacrificial anode (231) is electrically connected to the cells so as to expose the sacrificial anode to the environment.
