CHARGEABLE ALKALINE METAL ELECTRODE AND ALKALINE-EARTH METAL ELECTRODE HAVING CONTROLLED DENDRITE CRYSTAL GROWTH, AND THEIR MANUFACTURING METHOD AND METHOD OF APPLICATION

摘要

To provide a lithium electrode battery system that is not affected by dendrite crystal growth, while keeping cycle ability, ion conductivity, voltage and specific capacity of a battery.SOLUTION: A device for prolonging the battery life including an electrode having a metal part selected from a group including lithium, calcium, magnesium, sodium, potassium, and their combinations, an electrolyte permeable membrane, and a metal dendrite crystal seeding material placed between the electrode and membrane, is provided. The electrode, membrane and metal dendrite crystal seeding material are positioned in an electrolyte matrix. At least one dendrite crystal stretching from the electrode toward the electrolyte permeable membrane is integrated with at least one dendrite crystal stretching from the dendrite crystal seeding material.SELECTED DRAWING: Figure 1
