The present invention provides a negative electrode for a lithium metal battery and a lithium metal battery comprising the same, the negative electrode comprising: a first negative electrode including a lithium metal negative electrode; and a second negative electrode which is disposed on the first negative electrode and includes a coating layer including a carbon-based material. By using the negative electrode for a lithium metal battery, a lithium metal battery can have an improved charge and discharge efficiency and life time.

Negative electrode for lithium metal battery and lithium metal battery comprising same

An all-solid secondary battery includes a cathode; an anode including natural graphite; and a solid electrolyte layer between the cathode and the anode, wherein the natural graphite has an average particle diameter (D50) in a range of greater than about 10 μm to about 20 μm or less and includes an amorphous carbon coating layer.

All-solid secondary battery

Provided are an organic/inorganic composite electrolyte, an electrode-electrolyte assembly and a lithium secondary battery including the organic/inorganic composite electrolyte, and a manufacturing method of the electrode-electrolyte assembly. The porous organic/inorganic composite electrolyte, includes a first pore peak in a pore size range of about 100 nm to about 300 nm in a total pore distribution chart, and 50% or more of pores having a pore size range of about 100 nm to about 300 nm based on a total pore volume.

Organic/inorganic composite electrolyte, electrode-electrolyte assembly and lithium secondary battery including the same, and manufacturing method of the electrode-electrolyte assembly

An electrolyte additive for a lithium battery, an electrolyte including the electrolyte additive, and a lithium battery including the electrolyte additive are disclosed. The electrolyte additive for a lithium battery includes a sulfonylmethylisocyanide-based compound. The electrolyte additive including the sulfonylmethylisocyanide-based compound may form a protective layer having improved high-temperature stability on positive and negative electrodes of a lithium battery, thereby improving the safety of the lithium battery.
