A battery is a common device of energy storage that uses a chemical reaction to transform chemical energy into electric energy. In other words, the chemical energy that has been stored is converted into electrical energy. A battery is composed of tiny individual electrochemical units, often known as electrochemical cells (ECCs). Any ECC consists of three basic components:

Composition of NMC Batteries. NMC batteries, as the name suggests, derive their identity from a cathode that elegantly blends Nickel (N), Manganese (M), and Cobalt (C). The numeric suffix following the NMC label (e.g., NMC 111, NMC 532) represents the proportion of these elements in the cathode. For instance, NMC 111 boasts a cathode consisting of equal parts nickel,

Concluding remarks This paper presents a review of the recent advances in modelling structural battery composites, which store electrochemical energy and carry structural loads. As a battery, electrochemical cycling induces mechanical phenomena, such as deformation, damage, and degradation.
Structural batteries exhibit the unique ability to serve as both electrochemical energy storage and structural components capable of bearing mechanical loads with the frameworks or devices they are integrated into.
Cells, one of the major components of battery packs, are the site of electrochemical reactions that allow energy to be released and stored. They have three major components: anode, cathode, and electrolyte. In most commercial lithium ion (Li-ion cells), these components are as follows:
Multiphysics models are being developed to predict and evaluate the coupled performance of these batteries, drawing inspiration from conventional battery models. However, structural battery composites are expected to experience more significant deformation during operation than is induced by electrochemical cycling alone.
Utilizing structural batteries in an electric vehicle offers a significant advantage of enhancing energy storage performance at cell- or system-level. If the structural battery serves as the vehicle's structure, the overall weight of the system decreases, resulting in improved energy storage performance (Figure 1B).
