Abstract:
A newly designed dense SiOx@carbon nanotubes (CNTs) composite with a high conductivity of 3.5 S cm−1 and tap density of 1.13 g cm−3 was prepared, in which the CNTs were stripped by physical energy crushing and then coated on SiOx nanoparticles. The composite exhibits high capacities of 835 and 687 mAh g−1 at current densities of 100 and 200 mA g−1, which can be finely persevered over 100 cycles. Benefiting from this promising anode, two new full cells of SiOx@CNTs/LiMn2O4 and SiOx@CNTs/LiNi0.5Mn1.5O4 with high energy densities of 2273 and 2747 Wh kganode−1 (i. e. 413 and 500 Wh kgcathode−1), respectively, were successfully assembled and can cycle more than 400 cycles. Even with further cycling at the elevated temperature of 45 °C, the cells can still deliver relatively high capacities of 568 and 465 mAh ganode−1, respectively, over 100 cycles. Such desired high-energy lithium-ion batteries with working voltages over 4.0 V can be widely developed for diverse applications (e. g. in handheld devices, electric vehicles, and hybrid electric vehicles). The easy extension of the presented synthetic strategy and the configuration of high-energy battery system would be significant in materials synthesis and energy-storage devices.
