Just as some domestic brands that had originally made cars gradually entered the low-speed electric vehicle market.
Xichuan Province, Jiuzhou Automobile Factory.
After more than two months, Jiuzhou Automobile Factory had undergone tremendous changes.
Two newly built factories beside the original Jiuzhou Automobile Factory had now been completed.
They were no smaller than the original Jiuzhou Automobile Factory—in fact, they surpassed it.
One of the factories was Jiuzhou Electric Vehicle Factory, which produced two-wheeled electric vehicles.
The other was Hengxin Battery Factory, which supplied batteries specifically for Jiuzhou Mini and, in the future, Jiuzhou Two-Wheeled Electric Vehicle.
At that moment, inside Hengxin Battery Factory.
Led by Xu Yifan, the managers and senior executives of Jiuzhou Automobile were inspecting the battery production line, which had only just officially begun operating that day.
Unlike the Jiuzhou Automobile workshop, where it was easy to watch materials being processed into car parts, this facility had more equipment, but there was no way to witness the process of a material becoming a battery with one's own eyes.
Lithium-ion batteries were a complex system, consisting of cathodes, anodes, separators, electrolytes, current collectors, binders, conductive agents, and more.
The reactions involved included electrochemical reactions at the cathode and anode, the conduction of lithium ions and electrons, and the diffusion of heat.
Lithium battery production involved a lengthy process, with more than 50 steps.
Broadly speaking, the lithium battery manufacturing process could be divided into the front-end processes (electrode sheet production), the mid-stage processes (battery cell assembly), and the back-end processes (formation and packaging).
The goal of the front-end processes was to produce the cathode and anode sheets. The main steps were mixing, coating, calendering, slitting, tab making, and die cutting.
The equipment involved mainly included mixers, coating machines, calendering machines, slitting machines, tab-making machines, and die-cutting machines.
