A cathode (12) that includes manganese dioxide and a titanium oxy salt, preferably titanium oxy sulfate, is disclosed. Batteries (10) having cathode (12) have good performance characteristics. For example, the batteries (10) perform well in applications involving intermittent drains such as toys. Also disclosed is an electrochemical cell including a cathode (12) an anode (14) and a separator (16) disposed between the cathode and the anode. The cathode includes manganese dioxide and a titanium oxy salt.
L'invention se rapporte à une cathode (12) comportant du dioxyde de manganèse et un oxy-sel de titane, de préférence un oxysulfate de titane. Les batteries (10) dotées d'une telle cathode (12) présentent de bonnes caractéristiques de rendement. Ces batteries (10) sont, par exemple, bien adaptées aux applications impliquant un épuisement par intermittence, telles que l'utilisation dans des jouets. L'invention se rapporte également à une cellule électrochimique comportant une cathode (12), une anode (14) et un séparateur (16) disposé entre la cathode et l'anode. La cathode contient du dioxyde de manganèse et un oxy-sel de titane.
