According to (4), in order to identify the parameters of the lithium-ion battery, it is necessary to know U oc and U L. U L can be measured directly and U oc is usually acquired by the relationship between U oc and SOC, and there is a non-linear relationship between them .
We have shown recently that the state of charge (SOC) of a lithiated graphite electrode can be rapidly determined by measuring its color. Graphite is known to undergo a color change upon intercalation of lithium, from black in the pristine state to golden yellow in the fully charged state (composition LiC 6 ).
Higher mobility of lithium ions within composite electrodes could increase the power density of batteries and at the same time reduce ageing due to local overcharge or overdischarge of the electrodes.
Innovative analytical solutions are required to test individual battery components, like positive and negative electrode materials, separator, electrolytes, and more, during the development and quality control in production.
As the landscape of alternate energy methods for high technology and consumer goods such as, electric vehicles (EV) and bikes, smartphones and laptop advances, R&D is increasing to continually develop new types of batteries. In addition, QA/QC methods for lithium ion battery producers are also becoming more stringent.
