Current lithium-ion battery technology uses metal foil current collectors (copper, aluminium) sourced from large manufacturers based in Japan and China; there are no domestic UK suppliers, and all current collectors are imported. Existing current collectors are bulky and account for up to 30% of the total battery weight, reducing the gravimetric energy and power density. Replacing the metal sheet with a composite polymer conductive thin-film (polymer matrix containing electrically conductive particles) to reduce weight is a logical step forward.The vision for our collaborative project CONDUCTOR is to develop a lightweight and low-cost polymer current collector to replace the aluminium and copper foil current collectors used in lithium-ion batteries (LIB). Such batteries are one of the heaviest and most expensive components in a Battery Electric Vehicle (BEV). We estimate our polymer current collector will save some 4kg weight in a typical 50Kg automotive battery pack thereby increasing its charge and power density. Given there are no UK manufacturers of LIB current collectors, our ambition is to supply the growing need for LIB current collectors in line with growth of the Giga Factories in the UK to support the transition to 100% battery electric vehicle manufacture by 2035\.

当前的锂离子电池技术使用来自日本和中国大型制造商的金属箔电流收集器（铜，铝）；没有国内英国供应商，所有目前的收藏家都被进口。现有的当前收集器笨重，占电池总重量的30％，从而降低了重量的能量和功率密度。用复合聚合物导电薄膜（包含电导颗粒的聚合物矩阵）以减轻体重是合乎逻辑的一步。我们的协作项目导体的愿景是开发一个轻巧且低成本的聚合物当前收集器，以替换铝和铜纤维纤维的当前收藏家（Lithium-ion-ion Catchies（Lithium-ion Catchies）（Lithium-ion Catchies）（Lithium-ion Catchies（Lithium-ion Catchies））。这样的电池是电池电动汽车（BEV）中最重，最昂贵的组件之一。我们估计我们的聚合物电流收集器将在典型的50kg汽车电池组中节省约4kg的重量，从而增加其电荷和功率密度。鉴于没有英国LIB现有收藏家制造商，我们的野心是满足Lib当前收藏家日益增长的需求，符合英国Giga工厂的增长，以支持到2035年到2035年的100％电池电动汽车生产。
