Abstract

Un método de fabricacion de un cátodo que comprende: descomponer una mezcla que comprende un naftenato metálico e incorpora la mezcla descompuesta al cátodo. La mezcla puede comprender además carbon y un disolvente no acuoso. Preferentemente, la mezcla comprende aproximadamente entre 1 y 10% en peso del naftenato metálico y aproximadamente entre 30 y 70% en peso de carbon. El disolvente puede ser seleccionado de un grupo integrado por acetona y alcanos. En forma preferida, la descomposicion de la mezcla comprende calentar la mezcla a una temperatura que oscila aproximadamente entre 200 y 300 degree C, o bien poner en contacto el naftenato metálico con un agente de reduccion químico, el cual puede ser seleccionado de un grupo integrado por borohidruro de sodio, hidruro de aluminio litio, hidrazina e hidroxilamina. El metal puede ser seleccionado de un grupo integrado por manganeso, hierro, níquel y cobalto. La incorporacion de la mezcla descompuesta al cátodo puede comprender la incorporacion de carbon y un aglomerante al cátodo. El aglomerante puede ser politetra-fluoroetileno. Un método de fabricacion de una batería, que comprende hacer una solucion que comprenda un naftenato metálico y carbon en un disolvente; remover el disolvente y descomponer el naftenato metálico para formar un oxido metálico disperso en el carbon.
