Title:
INCORPORATION OF LITHIUM-ION SOURCE MATERIAL INTO AN ACTIVATED CARBON ELECTRODE FOR A CAPACITOR-ASSISTED BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/200609
Kind Code:
A1
Abstract:
A hybrid lithium-ion battery/capacitor cell(10) comprising at least a pair of graphite anodes(14,18) assembled with a lithium compound cathode(12) and an activated carbon capacitor electrode(16) can provide useful power performance properties and low temperature properties required for many power-utilizing applications. The initial formation of the graphite anodes(14,18) of this hybrid cell(10) combination is enhanced by including particles of a selected lithium compound with the activated carbon particles used in forming the capacitor electrode(16). The composition of the lithium compound is selected to produce lithium ions in the liquid electrolyte of the assembled cell(10) to enhance the in-situ lithiation of the graphite particles of the anodes(14,18) during formation cycles of the assembled hybrid cell(10).
