In addition, due to the relative particularity of lithium-ion battery, the welding technology has also put forward high requirements. If the welding strength is weak, the internal resistance of the battery string will increase, thus affecting the normal power supply of the battery string.
Batteries with higher energy and power densities are essential to enable the widespread use of electric vehicles (EVs) [1, 2]. Over the past few decades, lithium-ion (Li-ion) batteries have emerged as the state-of-the-art for portable electronics .
Over the past few decades, lithium-ion (Li-ion) batteries have emerged as the state-of-the-art for portable electronics . However, to accelerate the adoption of EVs, increasing charge rates is necessary [, , , ].
Laser welding is an efficient and precise welding method using high energy density laser beam as heat source. Due to heat concentration, fast welding speed, small thermal effect, small welding deformation, easy to realize efficient automation and integration [15, 16, 17], it is more and more widely used in power battery manufacturing. Figure 1.
In order to realize Li-ion batteries with high energy density, anodes with high areal capacity and electrode density were used in this work. Natural graphite (battery grade, SLC1506T, Superior Graphite) anodes were prepared using a pilot-scale roll-to-roll processing facility at the University of Michigan Battery Lab.
1. Introduction Lithium-ion batteries (LIBs), which are secondary rechargeable batteries are one of the most important energy storage technologies playing a significant role in the development of electronic devices, electric vehicles, house appliances, and energy storage as a result the demand for them is increasing rapidly [, , , ].
