Abstract

La invención divulga una estructura de capa de electrodo de bola de material activo, que principalmente incluye las bolas de material activo hechas de partículas de material activo, un primer electrolito mezclado localizado dentro de las bolas de material activo, y un segundo electrolito mezclado localizado fuera de las bolas de material activo. El primer electrolito mezclado está compuesto principalmente por electrolito deformable. El segundo electrolito mezclado está compuesto principalmente por electrolito con deformación relativamente menor qué el electrolito deformable del primer electrolito mezclado. La invención utiliza el primer electrolito mezclado para reducir de manera efectiva los problemas derivados del cambio de volumen de los materiales activos. Más aún, las diferentes configuraciones del primer electrolito mezclado y del segundo electrolito mezclado por dentro y por fuera de las bolas de material activo se utilizan para reducir la resistencia de transferencia de carga. También, se proporciona resistencia a la expansión para las bolas de material activo.
