Abstract

Ciertos dispositivos electronicos, tales como las cámaras digitales, cámaras fotográficas con flash de ultima generacion, algunos juguetes de alto consumoy juegos electronicos requieren de una tension de carga operativa sostenida de aproximadamente 2 .5 a 3 voltios y demandan mucha potencia la cual puede sersatisfecha con el uso de pilas de litio primarias. No obstante las pilas de litio primarias comercializadas actualmente pueden ser utilizadas para alimentarmuchos de estos dispositivos, es con veniente incrementar la capacidad de la pila en la medida de lo posible para hacerla más atractiva en el marco de talesaplicaciones. Es conveniente, entonces, incrementar la capacidad de la pila de litio (mAmp-h) para un tamano dado, en la medida de las posibilidades técnicas yeconomicas, sin sacrificar en forma significativa la salida de potencia de la misma. Una pila de litio primaria posee un conjunto de electrodos bobinado. Elconjunto de electrodos incluye un ánodo (40) que comprende litio, un cátodo (60) que comprende dioxido de manganeso y un separador permeable al electrolitoentre ellos (50). El conjunto de electrodos comprende una lámina catodica (62), una lámina anodica (40) y una lámina de separador permeable al electrolito (50)en tre ellas. Las láminas son arrolladas en una bobina en espiral. Un borde expuesto de cada vuelta de la lámina de separador luego es tratado con calor, porejemplo, aplicándole una placa caliente para moldear dicho borde expuesto a fin de obtener una m embrana separadora continua. La membrana separadora continua,constituida de esta manera, cubre y sella dicho borde de las vueltas adyacentes de la lámina catodica y de este modo provee de aislacion eléctrica a la misma.
