The distribution of relaxation times method (DRT) has been widely used to quantify the numbers and characterize the properties of the physico-chemical processes inside the Li-ion battery (LIB).
This illustration suggests that lithium-ion diffusion takes place by a cooperative interstitialcy or knock-on type mechanism in which the migrating interstitial Li-ion displaces the Li in the V layer into a neighbouring interstitial position in the alkali-metal layer.
When lithium inserts into or extracts from the active materials, the electrochemical reaction causes stress, and the DIS further assists the Li diffusion. The process that the stress and diffusion are strongly associated with each other is called mechanical–electrochemical coupling.
Based on the von Mises' theory of plasticity, Bower found the DIS was an important driving force for Li diffusion in lithium-ion batteries. [ 21] When lithium inserts into or extracts from the active materials, the electrochemical reaction causes stress, and the DIS further assists the Li diffusion.
An extended lithium-ion battery model is proposed, which simplifies the solid-liquid diffusion process compared with the full-order pseudo two-dimensional (P2D) model, in order to reduce computational complexity and enhance modeling speed. To simplify the model, the three-parameter method is utilized to simplify the solid-phase diffusion process.
Two physical processes determine the concentration of liquid lithium ions in the positive and negative regions: the first process is the diffusion motion based on concentration difference (Fick's law), and the other one is the motion of solid lithium ions in the positive and negative regions.
In order to simplify the liquid-phase diffusion process, Luo et al. 16 approximated the concentration of lithium ions in the liquid phase of the battery, using an exponential fitting to approximate the distribution of lithium ions in the positive and negative polar regions.
Battery welding is a crucial and precise manufacturing process that involves joining the various components of a battery through the application of controlled heat and pressure.
Of these, laser and ultrasonic welding processes dominate in EV battery manufacture – with laser welding the preferred solution for mass production – and continue to be improved and refined. “We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
Welding is a vitally important family of joining techniques for EV battery systems. A large battery might need thousands of individual connections, joining the positive and negative terminals of cells together in combinations of parallel and series blocks to form modules and packs of the required voltage and capacity.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.

If you drive an EV anywhere in the world, the odds are good that it has a battery from Contemporary Amperex Technology Company Limited — also known as CATL. The global battery leader opened in 1999 as “ATL” when it began developing lithium-ion batteries. In 2011, CATL opened, and a year later the company developed a partnership with BMW.
The Salton Sea in California has upwards of 3.4 million tons of lithium — enough to power 375 million EVs. Currently, the U.S. produces less than 7% of lithium batteries, while China makes 80% of them, with CATL as the largest EV battery manufacturer. U.S. companies aren't the only EV battery manufacturers trying to dethrone CATL.

Figure 1 shows the lithium-ion battery manufacturing process that includes electrode preparation, assembly, and formation. The battery formation stage has two key functions; on one hand to create the solid electrolyte interphase (SEI) on the anode and cathode electrolyte interphase (CEI) [1-2].
To complete the formation process, 3-5 cycles at 0.1 C at room temperature and 3-5 cycles at higher C-rate at higher temperature are required to control the thickness of the SEI layer. This takes several days and means the bottleneck in the battery formation process and the battery production itself.
