ANODE OG ANVENDELSE DERAV I ELEKTROKJEMISK LADBARE BATTERIER |
摘要 |
The disclosure describes an anode made of a thin metallic foil in discharged condition which is converted into a dense metallic alloy of an alkali metal during the first charge. The disclosure also describes an electrochemical rechargeable battery in discharged condition. The latter comprises an anode made of a thin metallic foil, such as aluminum, magnesium or tin, an electrolyte, for example a polymeric electrolyte, as well as a cathode based on an oxide, a sulfide or an halide, prepared in discharged condition and constituting a source of alkali metal preferably lithium. The cathode should be capable of freeing the alkali metal under a charge so that the latter is introduced into the metallic foil to form an alloy of the alkali metal and of at least a portion of the metal constituting the metallic sheet. To obtain the charged battery, it is merely sufficient to apply a charge during a certain period of time while the anode is being transformed into an alloy. Substantially improved properties during cycling. |
