Measuring device of the present invention includes a plurality of measuring sites for generating a plurality of optical paths and various dilutions. The range for concentration measurement and the measurement accuracy are enhanced due to the plurality of optical path length, and the interference on the measurement ranges and results caused by the concentration or the turbidity of suspended solid is reduced and removed by water sample dilution, and thus the characteristic wavelengths of the components in the water are measured. Next, the information of spectrum database is used to determine the ingredients which may exist in the water (qualitative analysis), and UV-VIS-NIR absorbance spectrum analysis is used to obtain the concentration of the respective ingredients in the water at the same time (quantitative analysis).

Changed optical path measuring device for component concentration of water and measuring method thereof

An anode protector of a lithium-ion battery and a method for fabricating the same are provided. A passivation protector () is formed on a surface of an anode () in advance by film deposition, such as atomic layer deposition (ALD). The passivation protector () is composed of a metal oxide having three dimensional structures, such as columnar structures. Accordingly, the present invention is provided with effective protection of the anode electrode structure and maintenance of battery cycle life under high-temperature operation.
