Disclosed herein are a multilayer separator for a lithium secondary battery capable of preventing an internal short-circuit due to growth of lithium dendrite, and a method of manufacturing the same.

Multilayer separator for lithium secondary battery capable of preventing short-circuit and manufacturing method thereof

A method of manufacturing a composite anode for a lithium ion battery and a composite anode for a lithium ion battery manufactured thereby. According to the method provide herein, since a metal catalyst precursor is reduced using Joule heating to obtain a carbon-metal catalyst composite layer, composite anode for a lithium ion battery having a large area in a short period of time can be provided, which is excellent in terms of economic feasibility. Further, since it is possible to manufacture a composite anode for a lithium ion battery with the improved lithium electrodeposition density and reversibility of lithium ions, a composite anode for a lithium ion battery having high capacity and improved life stability can be obtained.

Method of manufacturing composite anode for lithium ion battery

An electrolyte capable of lip roving the stability of a lithium-metal battery is provided. The electrolyte includes an organic solvent, a cosolvent, which is different from the organic solvent and includes a fluorine-based compound, and an additive having a lower lowest unoccupied molecular orbital (LUMO) value than the organic solvent.

Electrolyte for lithium-metal battery having improved stability

A metal air battery includes: cells, each of which includes a positive electrode, an negative electrode, and an electrolyte layer located between the positive electrode and the negative electrode; and a magnetic field generator configured to form a magnetic field in the cells. The magnetic field generator comprises a permanent magnet attached to one of the positive electrode and the negative electrode.

Metal air battery

The present disclosure relates to a lithium air battery and a manufacturing method thereof. A seed layer for inducing the growth of thin-film type discharge products is formed on a carbon positive electrode. The number of reaction regions that can react with lithium ions is increased, whereby high-speed discharging is possible. Since the seed layer induces the growth of the thin-film type discharge products, high-speed charging is also possible. In addition, since the seed layer induces the growth of the thin-film type discharge products, it is possible to increase the capacity of the battery. Furthermore, the occurrence of overvoltage in the lithium air battery is reduced, whereby the lifespan of the battery is increased while the stability of the battery is improved.

Lithium air battery and manufacturing method thereof

Provided herein is an anode for a lithium air battery with a long lifetime and high lithium ion conductivity and a method for preparing thereof. The anode includes a lithium metal and a protective layer disposed on one surface of the lithium metal, in which the protective layer includes an inorganic material-based solid electrolyte powder dispersed in a polymer matrix.

Anode for lithium air battery and preparation method thereof

There is provided an angular velocity sensor including first and second mass bodies provided within a first frame, a first flexible connector system connecting the first and second mass bodies and the first frame and that includes at least one sensor to detect displacements of the first and second mass bodies, a second flexible connector system connecting the first frame to a second frame provided separate from the first frame and that includes a driver to drive movement of the first frame relative to the second frame, so angular velocities can be measured based on the first and second mass bodies being enabled to rotate in a first axis direction and translated in a second axis direction, and based on the first frame being flexibly connected to the second frame so that a rotation displacement of the first frame is made in a third axis direction.
