Chongzuo

Prince Erachem's Chongzuo plant is dedicated to the production of electrolytic manganese dioxide (EMD) for cathodes in high quality alkaline batteries or in lithium-ion rechargeable batteries.

Chongzuo: Ideal Location


Ideally situated in the province of Guangxi, Southwest of China, the plant is close to an important rail and road hub that serves all regions of China and is only 150km from the ocean (and the port of Fangchen) to serve overseas customers. Its geographical position is also a strong asset as electricity, a key component of EMD, is abundant and its distribution is reliable in the province of Guangxi. Prince Erachem's strong and stable relationships with Guangxi government officials allows the Chongzuo plant to be part of important projects aimed at developing manganese activity in the Guangxi province.

Prince Erachem's Chongzuo facility is committed to high quality and high performance products and has developed different grades to answer needs of Chinese and other global battery manufacturers. Its state of the art production plant uses a large number of control systems and indicators to yield consistently high quality products. The Chongzuo plant not only requires very stringent specifications but aims for highly consistent product and top of the class EMD in terms of discharge performances. This attirbute is a key advantage for high drain battery usages. The facility is certified to ISO 9001.

Broad Range of EMD Product


Thanks to Prince Erachem's continuous improvement efforts, the Chongzuo facility has had regular EMD capacity increases to answer growing demand from Chinese, Asian, and European battery manufacturers. Today, it is the largest EMD plant in the world with 25,000 tons per year in production capacity. Prince Erachem continuously develops ways to optimize yields and reduce energy consumption, with the assistance of Erachem's internal quality, global process, and R&D teams. 

The GK-A, GK-B, or more recently the GK-S EMD were developed for specific segments of the battery market. Prince Erachem's Chongzuo team is also collaborating globally with sales, R&D and global process personnel to develop new products and grades that are optimized for today's lithium-ion batteries industry (such as low Fe, specific particle size distribution, and low alkali content).

The Chongzuo plant always strives for continuous improvement to ehnace its processes, optimize production, and advance quality and plant has developed processes which preserve natural resources (water, air, soil). As such all the water used in our manufacturing process is put back in the river cleaner than when it was drawn from it. Our Chongzuo facility also develops ways to optimize yields and reduce energy consumption.
