Abstract
Chemically modified (CM) rechargeable cathodes, based on a published and patented procedure developed at Ford Motor Company, have been prepared and their electrochemical performances investigated. The CM cathodes were characterized by (i) good rechargeability, (ii) high energy and power densities, (iii) achievement of high charging/discharging rates at a surprisingly constant working voltage, and (iv) low cost. Use of an ion‐selective separator enables the CM to be used in a secondary alkaline battery system with a Zn anode and appreciable cycle‐life to be realized. These characteristics make the secondary CM battery system a promising candidate for electric vehicle applications and also for many other market niches currently occupied by Ni‐Cd secondary and primary cells.
