Improved Performance of Batteries Through Optimized Intercalation, Increased Lithium Mobility and Reduced Plating
Improved Performance of Batteries Through Optimized Intercalation, Increased Lithium Mobility and Reduced Plating
May 10, 2022
If the charging rate of batteries shall be improved, it is worth taking a look at the mobility and intercalation processes of lithium ions within the battery components. After all, the way in which the ions can move within the materials (lithium mobility) and are inserted into the electrodes (intercalation) is the linchpin of optimization.
The operating principle of lithium-ion batteries (LIB) is based on the reversible “shuttling” of lithium ions between the electrodes, which are materials that can readily store lithium inside their crystal lattices. To achieve a fast charging process of the battery cell, a high rate capability, the lithium insertion rates into and mobility within the electrode materials as well as in the electrolyte should be high. Optimizing the lithium mobility hence plays a crucial role in battery performance.
