Hollow carbon spheres with rich nitrogen–oxygen dopants and highly disordered adsorption boundaries for advanced lithium and sodium storage

Sn0.1-Li4Ti5O12/C as a promising cathode material with a large capacity and high rate performance for Mg–Li hybrid batteries

“…Since their inception, Li-ion batteries have dominated the market of portable electronic devices and electric vehicles due to their high stability and long cycle life. [1][2][3][4][5] However, Li resources are limited, and the actual energy density of Li-ion batteries is approaching the technological limit, making the development prospects of traditional Li-ion batteries indistinct. [6][7][8][9][10] Mg is considered one of the options for the generation of energy storage technologies because of its abundance, low price, dendrite-free nature, and higher theoretical volumespecific capacity (3833 mA h cm −3 ) than that of Li (2046 mA h cm −3 ).…”
