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.

全球对化石燃料的转向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。电动汽车市场的扩大在很大程度上取决于提高续驶里程和降低成本。电动汽车的续航里程最终取决于电池的能量密度。从负极材料开发的角度来看，能量密度是其储存锂的容量的函数。与石墨相比，硅具有更大的容量（360 mAh/g），然而，由于在锂离子插入和提取期间严重的体积膨胀，硅基阳极在广泛的工业接受度方面不足。Talga已经开发出一种有前途的路线来生产Si/C复合阳极产品Talnode-Si，其显示出比商业石墨更高的可逆容量。该项目确定了该产品商业化的自然下一步，即研究Talnode-Si产品在工程技术、工艺规模和商业性方面的可行性。
