We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries.
The performance of the synthesized composite as an active negative electrode material in Li ion battery has been studied. It has been shown through SEM as well as impedance analyses that the enhancement of charge transfer resistance, after 100 cycles, becomes limited due to the presence of CNT network in the Si-decorated CNT composite.
The Si negative electrode is a negative electrode material that stores Li through insertion of Li into Si. The following SEM image was obtained as a result of observing how Li was inserted by charging single-crystal Si with 40% charged while using the single-crystal Si as the negative electrode.
These results demonstrate the possibility of improved all-solid-state batteries via metallurgical design of negative electrodes while simplifying manufacturing processes. Aluminum-based negative electrodes could enable high-energy-density batteries, but their charge storage performance is limited.
To meet the demands of long-range electric vehicles and electric flight, next-generation batteries must have higher energy density and improved safety. Solid-state batteries (SSBs) can potentially enable the use of new high-capacity electrode materials while avoiding flammable liquid electrolytes.
