Embodiment Construction
[0030] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. The drawings and descriptions are to be regarded as illustrative in nature and not restrictive. Throughout the specification, the same reference numerals denote the same elements.
[0031] For example, in the vacuum deposition apparatus and the vacuum deposition method using the vacuum deposition apparatus according to an exemplary embodiment of the present invention, lithium is deposited on the active substrate formed on the positive electrode and the negative electrode forming the electrode assembly of the lithium ion battery. Substance coated parts. In this case, in an exemplary embodiment, lithium is not deposited to t...

Provided are a vacuum evaporator and a vacuum evaporating method using the same. The vacuum evaporator allows evaporating subjects to be evaporated on a coated portion instead of an uncoated portion in a substrate. The vacuum evaporator comprises a roller, an evaporating source, a covering die, a detection sensor and a controller. The roller is used for supporting the substrate with the coated portion and the uncoated portion to move continously. The evaporating source is arranged on the opposite side of the roller and is used for providing evaporating subjects to the coated portion. When the covering die is moving between the opening of the evaporating source and the roller, the evaporating subjects are prevented from moving from the evaporating source to hthe coated portion. The detection sensor is used for detecting a first reference point and a second reference point that are disposed on the moving substrate. The controller is used for controlling the movement of the substrate and the covering die based on a fact that whether a third reference point and a fourth reference point, obtained according to the first reference point and the second reference point and arranged on the covering die, respectively correspond to the first reference point and the second reference point. Therefore, the evaporating subjects are evaporated onto the coated portion.
Description
technical field [0001] The described technology generally relates to a vacuum deposition apparatus for vacuum-depositing a deposition substance onto a substrate moving in a roll-to-roll manner and a vacuum deposition method using the vacuum deposition apparatus. Background technique [0002] Unlike primary batteries, rechargeable batteries (including, for example, Ni-MH batteries, lithium batteries, and lithium-ion batteries) can be repeatedly charged and discharged, and are manufactured in packs to be widely used in applications such as mobile phones, laptop Portable electronic devices such as computers and camcorders. [0003] The rechargeable battery includes an electrode assembly spirally wound in a jelly-roll shape by stacking positive and negative electrodes with separators interposed therebetween, a can accommodating the electrode assembly and electrolyte, and a cap assembly sealing the opening of the can. According to whether the active material is coated on the sub...
