The present disclosure relates to a lithium secondary battery assembled without an anode active material. Since the lithium secondary battery of the present disclosure does not contain an anode active material such as a lithium metal during the assembling ...

Provided are a composite and a method of preparing an anode slurry including the same. More particularly, the present invention provides a composite including a (semi) metal oxide, a conductive material on a surface of the (semi) metal oxide, and a binder,...

Disclosed is a method for preparing a graphene-like doped positive electrode material of a lithium-ion battery, comprising the following steps: stirring a liquid polyacrylonitrile solution for 8-72 hours at 80-300°C, to form a micro-cyclic LPAN solution; ...

An improved cathode material for nonaqueous electrolyte lithium electrochemical cell is described. The preferred active material is e-phase silver vanadium oxide (Ag2V4O11) coated with a protective layer of a metal oxide, preferably gamma -phase SVO (Ag1.2...

The present invention provides a non-aqueous electrolytic solution secondary battery which can obtain stable power regardless of a depth of discharge and which can detect residual capacity easily. Graphite particles G having a predetermined particle diamet...

Electrode films for lithium batteries are produced by using vinylidene fluoride/hexafluoropropylene (VDF/HFP) copolymer with an HFP content of less than 8 wt.% to make a solution, mixing this with electrochemically-active material, drawing out the paste to...

An electrochemical cell of either a primary or a secondary chemistry, is described. In either case, the cell has a negative electrode of lithium or of an anode material which is capable of intercalating and deintercalating lithium coupled with a positive e...
