Superior Electrochemical Performance and Storage Mechanism of Na_3V_2(PO_4)_3 Cathode for Room-Temperature Sodium-Ion Batteries

摘要

Energy storage and conversion remain significantly challenging to the research community. Among the candidates, lithium-ion batteries show great attraction and have been used in a wide range of applications, from small electronic devices, such as mobile phones and notebook computers, to increasing numbers of electric vehicles and large-scale energy storage equipments. However, the relatively high cost of lithium resources shows the potential problems in terms of the long-term and large-scale applications of lithium-ion batteries. Lithium resources are limited; lithium makes up about 0.0065% of the earth's crust and is unevenly distributed in South America.
