You can see that the outermost orbit of Lithium has 1 electron. During the chemical reaction, lithium loses this 1 electron and achieves the nearest noble gas configuration to become stable. And as the Lithium (Li) loses 1 electron, it forms Li + ion. Hence the ionic charge of Lithium (Li) is 1+. I hope you have understood the reason

The state-of-charge (SOC) of a Li-ion cell can be a macroscopic indicator of the state-of-health of the battery. The microscopic origin of the SOC relates to the local lithium content in individual electrode particles and the effective ability of Li-ions to transport or shuttle between the redox couples through the cell geometric boundaries.
