Abstract
Official abstract text for this publication.
A lithium secondary battery is provided with a higher capacity and a longer life. The lithium secondary battery includes: a cathode containing a material that is capable of inserting and desorbing lithium ions; a lithium ion conductive electrolyte; and an anode containing a material that is capable of occluding and releasing lithium metal or lithium ions, wherein the electrolyte contains indigo or indigo carmine, which is an organic compound.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lithium secondary battery comprising: a cathode containing a material that is capable of inserting and desorbing lithium ions; a lithium ion conductive electrolyte; and an anode containing a material that is capable of occluding and releasing lithium metal or lithium ions, wherein the lithium ion conductive electrolyte contains indigo or indigo carmine, which is an organic compound, at a concentration of 50 mmol/l. 2. The lithium secondary battery according to claim 1 , wherein the electrolyte contains a lithium ion conductive electrolytic solution. 3. The lithium secondary battery according to claim 1 , wherein the electrolyte contains a lithium ion conductive gel polymer electrolyte. 4. The lithium secondary battery according to claim 1 , wherein the electrolyte contains a lithium ion conductive solid electrolyte.
