example 1

[0123] Figure 9 and Figure 10 The shown prismatic secondary battery was fabricated by the following procedure. The secondary battery is formed as a lithium ion secondary battery in which the capacity of the anode 162 is expressed by a capacity component based on insertion and extraction of lithium.

[0124] First, the cathode 161 is formed. That is to say, lithium carbonate (Li 2 CO 3 ) and cobalt carbonate (CoCO 3 ) were mixed at a molar ratio of 0.5:1. After this, the mixture was fired at 900 deg C in air for 5 hours. Thus, lithium cobalt composite oxide (LiCoO 2 ). Subsequently, 96 parts by weight of lithium cobalt composite oxide as a cathode active material, 1 part by weight of graphite as a conductor, and 3 parts by weight of polyvinylidene fluoride as a binder were mixed to obtain a cathode mixture. After that, the cathode mixture was dispersed in N-methyl-2-pyrrolidone to obtain a paste cathode mixture slurry. Finally, both faces of the cathode current colle...

Abstract

An evaporation apparatus that is capable of stably forming a good quality thin film and is highly suitable for mass production is provided. The evaporation apparatus include an evaporation source discharging an evaporation material by heating, a retention member retaining an evaporation object, and a heat shield member that is located between the evaporation source and the evaporation object retained by the retention member, has an opening for passing the evaporation material in a state of vapor phase from the evaporation source to the evaporation object, and shields the evaporation object from part of radiation heat of the evaporation source. The heat shield member is located closer to the evaporation source than to the retention member.

Description

[0001] For cross-references to related applications [0002] The present invention contains subject matter related to Japanese Patent Application JP 2007-229850 filed in the Japan Patent Office on Sep. 5, 2007, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an evaporation apparatus for evaporating evaporation material sublimated from an evaporation source to an evaporation object, a method of manufacturing an anode using the apparatus, and a method of manufacturing a battery using the apparatus. Background technique [0004] In recent years, high performance and multifunctional mobile devices have been developed. Accordingly, for secondary batteries serving as power sources of mobile devices, it is required to realize their high capacity. Lithium ion secondary batteries meet such requirements. Recently, a lithium ion secondary battery having an extremely high capacity has been developed by using s...
