5分钟给汽车充满电?——以色列快速充电电池公司StoreDot探秘

2017-06-07 21:31:16   国际在线

多荣表示,第一代给手机充电的“闪充”电池已经研制成功,用户可能只需要比现在多花20美元就能买到这种“闪充”电池,1分钟就可以给手机充满电,可以待机一天,这种电池能充电500次,也就是说可以使用大约2年。目前,关于手机“闪充”电池的技术问题已经解决,现在遇到的难题是规模化生产,比如做到1天生产100万块电池的大规模生产。StoreDot公司正在日本和中国深圳寻找合作伙伴,预计将于今年底开始投产。多荣表示比较看好中国,因为中国有材料供应、大规模生产能力和广阔的手机市场需求。“大规模生产并不容易,你会看到我们把有机材料和纳米材料结合,这明显不是一般的锂电池。当我们在中国建造一个新的设备工厂的时候,我们得教会他们如何生产,这预计得花一年的时间。所以我们正在亚洲的几个地方选址。中国有一个地方,日本有一个地方,他们来这里,我们也派人过去,交流很多信息,交换材料和设备,就像我提到的那样,这是一个复杂的产品。在中国我们能大量生产,比如我们需要一天生产100万块电池,这是我们的首要目标。”

多荣表示,目前他们正在研发的第二代电池主要用于电动汽车,设计理念和第一代电池相同,但是因为电动汽车的电池需要容量更大,所以电池体积大,造价高,对安全性也有更高的要求。目前他们在材料上有很多选择,要经过多次实验,最终选择出一种性价比最高、可以大规模生产的环保材料来制造“闪充”电池。“第二代电池是给汽车充电的,现在技术还不成熟,正在发展阶段,我们可以通过演示证明其可行,但是还不稳定,可能还要花费一年左右的时间来制造性能稳定的汽车电池。”

除了稳定性外,电池成本也是重要因素。第一代“闪充”手机电池成本相对较高,如果直接用于电动汽车则价格昂贵,因此公司决定对现有的电池纳米材料配方进行筛选,辅以新的合成有机材料,以获得理想的电池核心物质,使得汽车电池实现5分钟快充的同时,其价格、规格和性能最优化,并达到量产化的程度。为此,StoreDot公司与欧洲的电动汽车制造商比如特斯拉等公司展开了合作,针对其研发计划,为它们三年后推出的新型电动汽车提供配套用的第二代“闪充”电池组。“如果你多花20美元或50美元买一个能一分钟快充的智能手机充电电池,没什么问题,但在一台电动汽车上有7000个电池单元,即使每个单元多收一美元,都太贵了,都是不可能的,新的电池材料必须和传统的锂电池成本相当,这就是为什么我们要研发第二代电池。”

多荣表示,如果汽车“闪充”电池面世,为满足汽车电池快充的需要,许多基础设施必须重新设计和建设,需要建立全新的充电设备、电线、接口,并提高供电能力。

多荣透露,StoreDot公司成立至今共获得6600万美元投资,其中2000万美元来自中国的投资者。由于转向手机电池量产的需要,公司近期完成了5000万美元的融资,同时公司为建立快充手机电池量产厂已着手2亿美元的融资工作。为获得资金,公司在考虑上市以及在何处上市的问题。

展望未来,多荣认为不仅是手机和电动汽车将使用“闪充”电池,其他使用电池的电子产品都将成为“闪充”电池的应用市场。“一旦大规模稳定生产,我们知道将会在手机和汽车上满足大量需求,它可以给任何东西充电:无人机、玩具、公共汽车、电动工具等等任何东西,每个人都想快速充电,你可以给你的照相机5分钟充满电,可以用一天。”
