Pangstar X-Star 46145 cylindrical battery is a high energy density system battery with single capacity above 18Ah. It adopts the full lug design process, which has low heat production, good consistency, high production efficiency and low manufacturing cost, and at the same time greatly reduces the internal resistance of the product, and has excellent performance in high and low temperatures, multiplication rate, and cycling.

X-Star high energy density sodium ion battery adopts rigid interface positive electrode technology and low tortuosity negative electrode structure. SEI self-healing electrolyte is added between the positive and negative electrodes to ensure the comprehensive performance of the battery. At the same time, X-star adopts the company's ultimate manufacturing technology, high-quality production lines, high-quality pole pieces and new tab designs to ensure battery safety and has passed six tests by the China Electronics Technology Standardization Institute of the Ministry of Industry and Information Technology(MIIT). The mass-produced battery cells have an energy density of up to 270Wh/L, a cycle number of 3,000, and can still discharge 85% in a low temperature environment of -20°C.
