摘要:
A secondary battery comprising a cathode, an anode, a separator and an electrolyte that comprises a eutectic mixture formed of: an amide group-containing compound, and an ionizable lithium salt. The anode comprises a metal or metal oxide having a potential vs. lithium potential (Li/Li+) within electrochemical window of the eutectic mixture. Because the secondary battery uses a eutectic mixture as an electrolyte in combination with an anode having a potential vs. lithium potential (Li/Li+) within the electrochemical window of the eutectic mixture, problems such as decomposition of an electrolyte and degradation of the quality of a battery are avoided. Also, due to the thermal and chemical stability, high conductivity and a broad electrochemical window of a eutectic mixture, it is possible to improve the quality as well as safety of a battery.

Disclosed is an electrolyte comprising (a) a eutectic mixture of an amide compound represented by the following chemical formula 1 or 2 and an ionizable lithium salt; and (b) a nitrile compound. The eutectic mixture and the nitrile compound in the electrolyte contribute to excellent thermal and chemical stability and sufficiently low viscosity and high ion conductivity. The electrolyte can be usefully applied as an electrolyte of electrochemical devices.

Disclosed is an electrolyte for electrochromic devices, which includes a eutectic mixture comprising: (a) a compound having an acidic functional group and basic functional group; and (b) an ionizable lithium salt. An electrochromic device using the same electrolyte is also disclosed. Because the electrochromic device uses the electrolyte comprising the eutectic mixture, which is cost-efficient and has excellent thermal and chemical stability, there are no problems related with evaporation and exhaustion as well as flammability of electrolyte. Additionally, it is possible to minimize side reactions with constitutional elements of an electrochromic device and electrolyte, thereby improving the safety. Further, it is also possible to improve the quality of an electrochromic device by virtue of a broad electrochemical window and high electroconductivity of the eutectic mixture.

Disclosed is an electrochromic device comprising: (a) a first electrode; (b) a second electrode; (c) an electrochromic material; and (d) a gel polymer electrolyte containing an ionic liquid. A method for manufacturing the same is also disclosed. The electrochromic device uses a gel polymer electrolyte comprising an ionic liquid. Therefore, there is no problem related with electrolyte leakage. Additionally, it is possible to manufacture electrochromic devices by using plastic materials, because the ionic liquid gel polymer electrolyte permits structural deformation with ease. Further, because the electrochromic device uses an ionic liquid, it is possible to minimize side reactions between constitutional elements of an electrochromic device and electrolyte.

The present invention relates to a refrigerator. In the present invention, a communication pad 60 is installed in one of the doors 51 and 53 for opening and closing storage spaces formed in a refrigerator main body 50. The communication pad 60 is detachably installed in a seating; space 58 of the door 53. While an upper end of the communication pad 60 is seated in the seating space 58 by an upper clamp 61, a lower end of the communication pad 60 is seated in the seating space 58 by a lower clamp 61′. The upper clamp 61 and the lower clamp 61′ are installed in the seating space 58 through hinge assemblies 65. Here, the hinge assemblies 65 are configured so that the upper and lower clamps 61 and 61′ rotate only by a force of a predetermined value or higher. According to the present invention constructed as above, it is possible to get advantages in that the communication pad 60 is securely mounted to and easily dismounted from the door 53.
摘要:
An icemaker for an ice supply system for preventing water from overflowing from the ice tray by vibration and/or shaking of the surrounding structure includes an icemaker, a container provided at a lower part of the icemaker and an ice chute for supplying the ice stored in the ice container. An ejector in the ice tray of the icemaker and a dropper device having an inclined upper surface at a side of the open top of the ice tray are provided for dropping the ice discharged upwardly by the ejector. The dropper has no gap or slot through which the ejector passes to prevent water overflow through the dropper. An overflow prevention device is provided at another side of the open top of the ice tray for preventing water filled in the ice tray from overflowing.

Disclosed are a full ice level sensing apparatus and method in which a full ice level of ice cubes in an ice bank is sensed by means of upward and downward movements of an elevating member, thereby minimizing an operational area of the elevating member required to sense the full ice level and increasing an effective volume of a freezing chamber. The full ice level sensing apparatus includes an elevating member disposed so as to rectilinearly move up and down into the ice bank, elevating means for rectilinearly moving the elevating member upward and downward, and sensing means for sensing whether or not the ice bank is at the full ice level based on the position of the elevating member.
摘要:
A image-forming apparatus has a light projection unit for projecting light onto a document. A reflection plate having a predetermined pattern corresponding to a size of the document reflects the light projected onto the document. The light reception unit receives the reflected light and forms an image. A control unit determines the size of the document based on the width of the document according to the pattern appearing on the image. When photocopying documents of several sizes using an automatic document feeder, documents are sorted based the document sizes and therefore, the documents can be read out at once without requiring re-setting of the image forming apparatus for different document sizes.
