摘要： A cathode active material for an all-solid-state battery including colloidal silica, a cathode active material, and a manufacturing method thereof are disclosed. It may be possible to achieve an enhancement in dispersion in a sulfide-based all-solid-state battery by controlling powder properties while reducing interfacial resistance between an electrolyte and a cathode active material of the sulfide-based all-solid-state battery.

摘要： Disclosed herein is a composite anode for a lithium secondary battery and a method of manufacturing the same. The composite anode for a lithium secondary battery where a lithium metal or a lithium metal composite is uniformly distributed and located may be manufactured using a simple pulse-electrodepositing method while minimizing an amount of lithium to be used. Moreover, a dendrite growth of lithium may be suppressed during charging because the lithium metal or the lithium metal composite is uniformly located on the porous conductor.

摘要： Disclosed is a method of manufacturing a cathode active material for an all-solid-state battery by using sonication. The method includes: preparing a cathode active material; preparing a coating solution, the coating solution including a lithium-containing precursor and a transition-metal-containing precursor; preparing an admixture by adding the cathode active material to the coating solution; sonicating the admixture at a first temperature; and forming a coating layer including a lithium transition metal oxide on the cathode active material by heat-treating a resultant of the sonicating at a second temperature that is a temperature higher than the first temperature.
