   2016年第三十一届夏季奥林匹克运动会将在巴西里约热内卢举行，来自世界各地的数万名运动员将为亿万观众奉献最高水平的“体育盛宴”，据此，读图回答下题．

电动汽车的核心部件是超级锂电池。2016年7月，世界最大的电动汽车生产商——美国特斯拉在位于美国西部内华达州的首座超级电池工厂举行了揭幕仪式（如下图）。整座工厂占地面积为3200英亩，足足有107个足球场那么大。工厂2020年投产后，当满负荷生产时，超级电池工厂的员工将达到6500人，电池产量将达到2013年全球电池产量的总和。制造电池所需的钴、石墨等原料来自世界各地，生产技术来自日本。从原料到成品整个电池生产、电池回收过程将在一个工厂内完成，厂房顶全部铺设太阳能电池板。据此完成以下问题。
