摘要:
A transistor includes an MILC (metal-induced lateral crystallization) region formed on a substrate with a semiconductor material and including a channel region, and a plurality of MIC (metal-induced crystallization) regions formed on the sides of the MILC region with a semiconductor material, wherein at least one boundary between the MILC region and one of the MIC regions is located outside the channel region. A method of fabricating a transistor includes the steps of forming an MILC (metal-induced lateral crystallization) region on a substrate using a semiconductor material, the MILC region including a channel region, and forming a plurality of MIC (metal-induced crystallization) regions formed on sides of the MILC region using a semiconductor material, wherein at least one boundary between the MILC region and one of the MIC regions is located outside the channel region.
摘要:
Provided is a method of manufacturing a lithium secondary battery, the method including: preparing positive and negative metal foams having a plurality of first pores; controlling first pore sizes of the metal foams depending on an application; filling the first pores with a slurry obtained by mixing a positive electrode active material or a negative electrode active material, a binder, a conductive material, and an organic solvent; heat-treating the metal foams to form second pores having a size smaller than those of the first pores. The first pore size of the metal foam can be controlled, so that a high capacity and high output battery can be manufactured depending on the usage.
摘要:
Provided is a lithium negative electrode having metal foam capable of significantly improving the safety and reliability of a lithium secondary battery by suppressing volume expansion and consumption of a lithium material due to charge/discharge repetition of the lithium secondary battery, and a lithium secondary battery using the lithium negative electrode. The negative electrode for a lithium secondary battery includes: a negative electrode current collector made of metal foam having a plurality of pores whose inner portions are empty; and a lithium thin film attached to a rear surface of the electrode current collector.
