Abstract

Se revela un método de predescarga de una batería nueva según el cual se forma una película litiada estaable en el ánodo por medio de una pequenadescarga de capacidad con el objeto de recuperar rápidamente la tensión de circuito abierto de lamisma. La batería comprende un cátodo que utiliza litiometálico como material activo, un ánodo que utiliza dióaxido de manganeso como un componente principal del material activo, y un electrólito que comprende unelectrólito inorgánico disuelto en un disolvente no acuoso que contiene por lo menos carbonato de propileno. La batería es predescargada utilizando unacorriente pulsativa. La descarga no es superior al 2% de la capacidad de descarga total. Una película litiada que se forma en la porción ánodo, mientrasse oxida parcialmente en iones de litio, es emparejada. A través de una pequena descarga, puede eliminarse una porción de alto potencial y suprimirse lareacción de generación de gases. Además, se alarga la vida útil y mejorala uniformidad de tensión de batería.A new battery pre-discharge method is disclosed whereby a stable lithium film is formed at the anode by means of a small capacity discharge in order to quickly recover the open circuit voltage therefrom. The battery comprises a cathode using lithi-metal as the active material, an anode using manganese dioxide as a main component of the active material, and an electrolyte comprising an inorganic electrolyte dissolved in a non-aqueous solvent containing at least propylene carbonate. The battery is pre-discharged using a pulsating current. The discharge does not exceed 2% of the total discharge capacity. A lithiated film that forms in the anode portion, while partially oxidized to lithium ions, is paired. Through a small discharge, a high potential portion can be removed and the gas generating reaction suppressed. In addition, it extends the service life and improves the uniformity of battery voltage.
