WebJun 4, 2013 · Carbon coated TiO2–SiO2 nanocomposites (CTSO) with high grain boundary density fabricated by a simple hydrothermal approach have been investigated as anode materials for lithium-ion batteries. The CTSO anode exhibits superior high-rate capability and excellent cycling performance. WebMar 8, 2024 · Calorimetric measurements showed that the excess grain-boundary energy is around 0.40–0.55 J/m 2 for grains of about 100 nm, but drops to 0.28 and 0.21 J/m 2 for grains with sizes of 65 and 40 nm, respectively. These values are only about half of the conventional GB energy 135 ( Figure 5 ).

WebDec 6, 2024 · Because the grain size could not be held constant, the measurements were pooled into different grain size regimes within 100 nm of the nominal value: 300 ± 100, 500 ± 100 and 700 ± 100 nm. These measurements were made on samples grown in the same solution concentration of 0.36 mol/L Ni sulfamate and 0.65 mol/L boric acid. how fake is undercover boss
