Abstract: Disclosed are an organic electrolyte for a lithium-ion battery and a lithium-ion battery comprising the same, wherein the electrolyte includes a base electrolyte containing a lithium salt dissolved in an organic solvent, and diphenyloctyl phosphate added thereto in an amount of 0.1 to 20 wt %. As compared to a conventional organic electrolyte using only a carbonate ester-based solvent, such as ethylene carbonate, ethyl methyl carbonate, etc., the lithium-ion battery employing the organic electrolyte can improve thermal stability of an electrolyte solution, high-rate performance, and charge/discharge cyclability of a battery, while maintaining battery performance of the base electrolyte.

Abstract: Disclosed are a highly corrosion-resistant aluminum alloy for a heat exchanger tube and a method for manufacturing a heat exchanger tube using the same. The highly corrosion-resistant aluminum alloy includes 0.05 to 0.5 wt % of iron, 0.05 to 0.2 wt % of silicon, 0.6 to 1.2 wt % of manganese, 0.15 to 0.45 wt % of copper, 0.05 to 0.3 wt % of at least one of zirconium and boron, and the remainder of aluminum and impurities. The aluminum alloy aluminum alloy for a heat exchanger tube improves corrosion resistance without affecting the physical properties other than corrosion resistance, through improvement in composition of the alloy, and ensures sufficient corrosion resistance without thermal arc spraying of zinc, resulting in a simple process, which leads to improvement in manufacturing efficiency and productivity of products.
