Superionics

Abstract

This research concerns the investigation of the physical properties of the components of a new solid state microbattery. This battery consists of a lithium metal anode, a lithium borate glass separator, and a cathode of the layer compound Indium Selenide which readily intercalates lithium ions and which is also an electronic conductor. The battery operates by the passage of lithium ions between the electrodes through the borate glass separator and the passage of electrons between the electrodes via the external circuit. A single battery of this type produces a voltage of 2.7 V, can be discharged with a current density of 50 microamps/sq cm and can achieve a specific energy 300 watt hours. It is the ultimate objective of this project to produce systems composed of many microbatteries for applications requiring high voltage, high current density and/or high energy density. In order to achieve this objective, it is necessary to have a fundamental understanding of fast ion transport in the lithium borate glasses and of both fast ion and electron transport in the layer compound.
