Bipolar solid state battery with insulating package

Abstract

In accordance with one embodiment, a bipolar solid state battery includes a first cell stack including a first solid-electrolyte separator positioned between a first cathode and a first anode, a first base layer including a first base portion positioned directly beneath the first anode, a second cell stack including a second solid-electrolyte separator positioned between a second cathode and a second anode, a second base layer including a second base portion positioned directly beneath the second anode, and a thermally insulating medium surrounding the first cell stack and the second cell stack.

Description

[0001] cross reference [0002] This application claims the benefit of US Provisional Application No. 61 / 870,836, filed August 28, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to batteries, and more particularly to solid state batteries. Background technique [0004] Rechargeable lithium-ion batteries are attractive energy storage systems for portable electronics and electric and hybrid electric vehicles because of their high specific energy compared to other electrochemical energy storage devices. A typical Li-ion cell contains a negative electrode, a positive electrode, and a separator region between the negative and positive electrodes. Both electrodes contain active materials that reversibly intercalate or react with lithium. In some cases, the negative electrode can include lithium metal that can be electrochemically dissolved and deposited reversibly. The separator contains an electrolyte wi...
