WebWith the increased need for high-rate Li-ion batteries, it has become apparent that new electrode materials with enhanced Li-ion transport should be designed. Interfaces, such as twin boundaries (TBs), offer new opportunities to navigate the ionic transport within nanoscale materials. Here, we demonstrate the effects of TBs on the Li-ion transport … WebDec 22, 2014 · This website requires cookies, and the limited processing of your personal data in order to function.

WebHowever, this value is necessary to drive the Li+ ions though the naturally formed Li2O on the surface of Li metal (see the discussion in literatures: M. T. McDowell et al. Nano Lett., 2013, 13, 758; X. H. Liu et al. Energy Environ. Sci., 2011, 4, 38 44). The over-potential applied here is just to drive/introduce lithium to go into the SnO 2 ... WebMay 21, 2015 · Twin boundaries, small, symmetrical defects in materials, may turn into an chance to improve lithium-ion batteries. Defects are usually regarded as flaws, but researchers at Michigan Technological University see them as opportunities. The so-called defective twin boundaries acts as energy highways and could help get better performance … WebJan 14, 2015 · It is proved that the lithium ions prefer to intercalate in the vicinity of the (101̅) TB, which acts as conduit for lithium-ion diffusion inside the nanowires, and density functional theory modeling shows that it is energetically preferred for lithium ions to accumulate near the TB compared to perfect neighboring lattice area.
