You''ve probably heard of lithium-ion (Li-ion) batteries, which currently power consumer electronics and EVs. But next-generation batteries—including flow batteries and solid-state—are proving to have additional benefits, such as improved performance (like lasting longer between each charge) and safety, as well as potential cost savings.
Modern battery technology offers a number of advantages over earlier models, including increased specific energy and energy density (more energy stored per unit of volume or weight), increased lifetime, and improved safety [4].
New energy vehicle (NEV) power batteries are experiencing a significant "retirement wave", making second-life utilization (SLU) a crucial strategy to extend their lifespan and maximize their inherent value.

Modelling helps us to understand the battery behaviour that will help to improve the system performance and increase the system efficiency. Battery can be modelled to describe the V-I Characteristics, charging status and battery''s capacity. It is therefore necessary to create an exact electrical equivalent model that will help to determine the battery efficiency. There are
Cost: Demand for electric vehicles has generally been lower than anticipated, mainly due to the cost of lithium-ion batteries. Hence, cost is a huge factor when selecting the type of lithium-ion battery. Types of Lithium Batteries. Now that we understand the major battery characteristics, we will use them as the basis for comparing our six types of lithium-ion batteries.
Classification of battery models One of the first steps of battery modeling is to decide, what is the purpose of the modeling. Every application of the model requires slightly different approaches and parameters. There is no strict rule, how to categorize battery models, same models can belong to more than one class.
Battery model plays an important role in the simulation of electric vehicles (EVs) and states estimation of the batteries in the development of the model-based battery management system.
Battery modeling is an excellent way to predict and optimize some batteries’ basic parameters like state of charge, battery lifetime and charge/discharge characteristic. Over the years, many different types of battery models have been developed for different application areas.
Batteries can be classified according to their chemistry or specific electrochemical composition, which heavily dictates the reactions that will occur within the cells to convert chemical to electrical energy. Battery chemistry tells the electrode and electrolyte materials to be used for the battery construction.
The analytical models describe the battery at a higher level of abstraction than the electrochemical and electrical circuit models . These models perform well for the SOC tracking and runtime prediction under specific discharge profiles. The simplest analytical model is called Peukert’s law .
The Seven commonly used battery models: Shepherd model, Unnewehr Universal model, Nernst model, Combined model, Rint model, Thevenin model, and the DP model are summarized, the model equations are deduced and the model parameters’ identification method is designed based on the recursive least squares method with an optimal forgetting factor.
