UK-Si: Creating a Silicon/carbon anode supply chain for UK automotive Li-ion battery industry

全球对化石燃料的转变正在导致锂离子电池应用的繁荣，从电动汽车到储能系统。预计到2025年，欧洲市场的价值将达到2500亿欧元。扩大电动汽车市场在很大程度上取决于提高续航里程和降低成本。电动汽车的续航里程最终是由电池的能量密度决定的。从负极材料发展的角度来看，能量密度是其储存锂的能力的函数。与石墨相比，硅具有更大的容量(360mAhg)，然而，由于锂离子插入和提取过程中严重的体积膨胀，硅基阳极在工业上的接受度很低。Talga开发了一种很有前途的方法来生产硅/碳复合阳极产品Talnode-Si，显示出比商业石墨更高的可逆容量。该项目为该产品的商业化奠定了自然的下一步，即从工程技术、工艺放大和商业化方面研究Talnode-Si产品的可行性。

A global shift away from fossil fuels is leading to a boom in lithium-ion battery applications, ranging from electric vehicles to energy storage systems. The market is projected to have a value of €250 billion in Europe by 2025\. Ramping up the electric vehicle market relies heavily on improving the driving range as well as on reducing cost. Range of an EV is ultimately defined by energy density of the battery.From anode material development standpoint, energy density is a function of its capacity to store lithium. Silicon has a much larger capacity compared to graphite, (360 mAh/g), however, Si-based anodes fall short in wide industrial acceptance due to severe volume expansion during Li-ion insertion and extractionTalga has developed a promising route to produce a Si/C composite anode product, Talnode-Si, showing a higher reversible capacity than commercial graphite. The project establishes the natural next step towards commercialisation of this product i.e. studying the Talnode-Si product feasibility in terms of its engineering technology, process scale up and commerciality.
