Because lithium-ion batteries (LIBs) have a high specific energy, long life, excellent safety, fast-charging capability, low self-discharge, and eco-friendliness, a vehicle equipped with LIBs has a relatively long electric endurance mileage and can meet the power requirements of electric vehicles [9, 10, 11].
The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative characteristics such as high energy density, long cycle life, environmental friendliness, high power density, low self-discharge, and the absence of memory effect [, , ].
In the structure of new energy vehicles, the power battery pack structure is the most important power component, thus, it needs to be designed with a safer and more reasonable structure to meet the requirements of shock resistance and durability.
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:
With the rapid development of new-energy vehicles worldwide, lithium-ion batteries (LIBs) are becoming increasingly popular because of their high energy density, long cycle life, and low self-discharge rate. They are widely used in different kinds of new-energy vehicles, such as hybrid electric vehicles and battery electric vehicles.
Lithium-ion power batteries are generally composed of single batteries in a certain arrangement to form an automobile power battery pack. A lithium-ion battery is mainly composed of a positive electrode, negative electrode, diaphragm, and electrolyte. It works by moving the lithium-ion between the positive and negative electrodes.
