1. Solvent Engineered Synthesis of Layered SnO Nanoparticles for High-Performance Anodes Seán R. Kavanagh, Sonia Jaskaniec, Seán Ryan, Joao Coelho, David O. Scanlon, Aron Walsh, Valeria Nicolosi sean.kavanagh.19@ucl.ac.uk Nov 2nd 2020, F.EL04.19.20
2. Synthesis-Morphology Relationship
3. SnO Wulff Shape a. Predicted equilibrium crystal shape b,c. Wulff shape only including surfaces with energies < 0.6 J/m2 d,e. SEM micrographs of SnO platelets synthesised in H2 O
4. Nanoplatelet Battery Performance Maximum capacity of 875 mAh.g-1 c.f. 372 mAh.g-1 for graphite anode (in Li-ion batteries)
5. Conclusions • Morphology control of solution-grown SnO nanoplatelets is possible via solvent effects on the kinetics and thermodynamics of crystal growth. • Nano-structured anode materials permit higher ion flux and thus greater battery charge capacity. arXiv: 2011.02397
