  陈璇:非常感谢协会给了我们这次机会,来给大家讲一下天鹏现在在智能制造这一块的一些新的布局和进展。刚才因为有幸刚好听了亿纬袁总这块的思考和介绍,在那个之前我们也听了三星的,因为也是中国籍的高管的介绍,确实在之前很长时间大家的感受或者体会觉得我们中国的电芯厂产量大、但是质低,水准还比较低。我觉得今天我们在路上,我们在往国际一线水准的路上,我们袁总刚才分享了很多非常实在的,作为锂电企业遇到的一些挑战和他们做的一些思考,我在这个地方也把天鹏这几年的一些判断和想法跟大家做一个分享。

  总体来讲,大的方向,我跟袁总的判断是一样的,就是说未来不会是所有电池的过剩,应该是劣质电池的过剩,或者说性价比不高的电池过剩,真正能够存活下来的可能有这么几点。第一个,有足够的能力能够把产品做好,这是首先的一个条件。第二个,确实能够把性价比提高,就是把价格能够再做的更便宜一些。这里面我们做电芯的都知道,原材料的成本各家的采购差异没有那么大,但是可能从成品率、合格率到全生命周期电池的性能来看的话,这个成本差异会非常大。所以我们现在也是致力于说我们能不能一起通过各方面的努力,能够把我们从原材料到制成过程、到最后给客户带来的成本,到我们自己售后的成本,整个成本把它降下来。这个过程其实就是一个非常大的挑战,因为电池是一个类似于有点像人的身体一样,就是到现在医学发展的今天,还是很难说清楚癌症的来源是什么。大家都知道,电池最可怕的就是它内部的一些短路或者安全性的问题,但是这些问题首先来自于设计,然后是制造,然后是使用,每个过程都至关重要。所以我们做电芯厂的,只能说我们从设计到制造的过程,我们把它做的更优秀、更精准、更精致,确保在我们能够关注到的细节上面把它做好。

  但是我们这几年下来的体会是什么呢?就是说随着能量密度越来越高,实际上他的安全性是越来越低的,是一个不可回避的矛盾,当你的能量密度高了,你的高镍也好、能量膨胀也好,你的活性分子越来越不受你的控制,你怎么保证你做的更高的能量密度的产品符合现在更安全的这样一个趋势?更高能量密度以后,我们大家没有办法容忍它更不安全,但是事实就是这样,怎么办,就是要提高控制能力。

  这个地方是我列举了一些在锂电生产过程当中,对高能量密度的电芯会提出的更高的要求,比如说高镍体系和硅碳需要更低的制成湿度和更好的粉尘控制,更薄的薄膜。更薄的薄膜为了更高的容量,但是更薄的薄膜意味着安全性更差、强度更低,包括我们这两天一直在讲涂覆的陶瓷薄膜,即使是涂覆的陶瓷薄膜,当陶瓷薄膜更薄的情况下,对隔膜的材料要求也是不一样的,所以需要更高的涂覆、碾压、分切、卷绕设备,而且还需要更洁净的空间。边锋游戏当你的隔膜在20以上的时候,其实一定量的粉尘是不会对电池不管是短期还是长期造成内短路的风险,但是当隔膜做到16以下甚至12以下的时候,很多细小的空气里的粉尘或者制成当中的粉尘,都有可能造成这个电芯的内部短路,所以这个要求已经完全不一样了,用厚隔膜的时代和做薄隔膜的时代是完全两回事。网传的一个版本是说,那个问题也跟隔膜比较薄有关系,我相信一定是其中的原因之一,但是即使是我们的老大哥,他们可能也会出现走钢丝的时候有一些风险,但是我们原来都是走红光大道的,突然走到小道上,其实对我们这些厂家的要求,我希望大家怎么重视都不为过,只有做的非常彻底能够做到我们能想到的所有的东西,他也不为过。其他的大家就看一下,因为时间有限。
