Core-shell materials for lithium-sulfur batteries Apart from LIBs, core-shell structures are also employed in LSBs to improve their electrochemical performances. LSBs are promising electrochemical devices for future energy storage due to their high theoretical capacity (1675 mA h g −1) and high energy density (2600 W h kg −1) , , .
Rechargeable lithium-ion batteries are widely used for consumer electronics and exhibit great potential for electrical vehicle and grid-scale energy storage 1, 2, 3, 4. The first charging process, in which lithium ions and electrons move from cathode to anode, is critical for lithium-ion battery operation.
Develop your high-performance battery powder materials of the future with Glatt Powder Synthesis! The cathode takes up almost half of the battery’s material expenses and drives up its price. Therefore, the development of cost-effective, highly efficient, and durable materials is of utmost importance.
Both Si and graphite anodes are successfully prelithiated with these nanoparticles to achieve high first-cycle Coulombic efficiencies of 94% to >100%. The LixSi–Li2O core–shell nanoparticles enable the practical implementation of high-performance electrode materials in lithium-ion batteries.
The energy density of cathode materials for lithium-ion batteries can be greatly increased by increasing the Ni content, but this increase leads to deteriorated electrochemical and thermal stability of materials in the charged state due to the instability of tetravalent nickel in the oxide phase.
Anode prelithiation is used to treat the initial capacity loss and low Coulombic efficiency in lithium-ion batteries, but existing methods are not effective. Here, the authors report lithium silicide–lithium oxide core–shell nanoparticles as a promising prelithiation reagent.
