Abstract:

The present invention relates to electrochemical electrodes, and more specifically to a method of fabricating a magnesium titanium bipolar electrode. 2 Description of the Prior Art There continues to be a need for energy sources with a high energy density. In particular, there is a need for high energy density energy sources that can power unmanned undersea yehicles UUVs Such energy sources when used to power such vehicles are required to have an energy density greater than 400 Wh kg -1. They also need to have long endurance and quiet operation. Additionally, they must be relatively inexpensive, environmentally friendly, safe to operate, reusable, capable of a long shelf life and not prone to spontaneous chemical or electrochemical discharge. The zinc silver oxide ZnAgo electrochemical couple has served as a benchmark energy source at 100 Wh kg -1 for undersea applications. Because of its low energy density, however, it is not suitable for unmanned undersea vehicles whose energy density requirements are four times those of the ZnAgo electrochemical couple.
