In-Situ TEM and DFT Study of Large Cation Transport and Failure Mechanism In Single SnO2 Nanowire
Direct measurement reveals that Na ion diffusion is 30 times slower than Li ion. Na insertion softens nanowire and causes significant deformation to lead to easy deformation of the product. Pore formation upon Na ion removal leads to poor cycliability of the SnO2 electrode Read More
