The present disclosure relates to an electrolyte for a lithium secondary battery, and in particular, to a liquid electrolyte capable of stabilizing lithium metal and suppressing lithium dendrite growth, and a lithium secondary battery including the same. The lithium secondary battery provided with the electrolyte according to the present disclosure has an excellent cycle-dependent capacity retention rate, and accordingly, is effective in improving a battery lifespan property.

Electrolyte for lithium secondary battery and lithium secondary battery comprising same

The present invention relates to an electrode assembly for a lithium secondary battery, a lithium secondary battery and a battery module comprising the same, and in particular, to an electrode assembly for a lithium secondary battery capable of, by changing a form of a lithium negative electrode current collector and thereby minimizing an interface of the negative electrode current collector exposed to a electrolyte, fundamentally blocking a corrosion reaction focusing on the negative electrode current collector caused by the liquid electrolyte in the art, and a lithium secondary battery and a battery module including the same.

Electrode assembly having plurality of lithium metal sheets or lithium alloy sheets for lithium secondary battery, and lithium secondary battery and battery module including same

The present invention relates to an electrolyte solution for a lithium-sulfur battery and a lithium-sulfur battery including the same. The electrolyte solution for a lithium-sulfur battery according to the present invention exhibits excellent stability, and may improve a swelling phenomenon by suppressing gas generation during lithium-sulfur battery operation.

Electrolyte for lithium-sulfur battery and lithium-sulfur battery comprising same

The present invention relates to an electrolyte containing a polydopamine and a lithium-sulfur battery including the same and, more particularly, to a technique in which polydopamine contained in an electrolyte adsorbs a lithium polysulfide eluted from a positive electrode of a lithium-sulfur battery. When using an electrolyte, according to the present invention, to which polydopamine particles are added, the polydopamine particles dispersed in the electrolyte act to adsorb lithium polysulfide eluted from a positive electrode during the charging and discharging, and thus can suppress the diffusion thereof, i.e., suppress a shuttle reaction, thereby improving the capacity and lifetime characteristics of the lithium-sulfur battery.
