The new generation of disruptive battery technology abandons traditional negative electrode active materials and relies on in-situ deposition of metal ions to form dynamic negative electrodes, greatly improving energy density while suppressing dendrite growth from the root, and possessing excellent safety performance. The production process is more streamlined, effectively reducing material and manufacturing costs. With characteristics such as high specific energy, high safety, low cost, and strong adaptability, it is widely used in high-end energy storage, new energy vehicles, special power supplies, and other fields.
