Implications of Cycle Stability of Silicon Alloy Anodes on Driving Range, Costs and Business Models of Electric Vehicles

摘要

1. LiB prices have reached levels, which enable further disruptive technologies (electronics, stationary, mobility) 2. Silicon/graphite blend electrodes are reality and are part of the main stream LiB 3. The next challenge is to bring wt% of Silicon up to 50 % starting from around 5 % 4. Plenty of room for improvement for extended life time of cells with high Silicon levels: a. Pre-Lithiation b. DoDs<100% c. Formulation optimization d. Electrolyte additives 5. Real life driving cycle testing necessary!!!!!
