On March 31, the “High-tech Lithium Iron Phosphate Pyrometallurgical Construction Project Environmental Impact Assessment” of Bijie Ronbay Lithium Battery Materials Co., Ltd. conducted its first public announcement.
Project Name: Bijie High-tech Lithium Iron Phosphate Pyrometallurgical Construction Project
Construction Address: Bijie High-tech Zone, Bijie City, Guizhou Province
Construction Unit: Bijie Ronbay Lithium Battery Materials Co., Ltd.
Nature of Construction: New Construction
Project Overview: This project involves adaptive renovation based on the existing buildings and facilities of the former Lifan factory area, while simultaneously constructing necessary public utilities and auxiliary facilities. The overall plan is to build a pyrometallurgical production line with an annual capacity of 1 million tons of lithium iron phosphate. The project is implemented in three phases: Phase I forms an annual production capacity of 300,000 tons, Phase II adds an additional 400,000 tons per year, and Phase III adds another 300,000 tons per year (this evaluation covers only Phase I). In the process, the yellow material is sintered at high temperature under nitrogen protection to produce lithium iron phosphate (LiFePO4), with water and carbon dioxide as by-products. The resulting lithium iron phosphate cathode material is then crushed, iron-removed, packaged, and stored. Supporting public auxiliary systems such as power supply and distribution, circulating water, nitrogen generation, and gas pressure regulation are also constructed.
Bijie Ronbay Lithium Battery Materials Co., Ltd. was established in February 2026 and is a wholly-owned subsidiary of Ningbo Ronbay New Energy Technology Co., Ltd. Ronbay Technology is the world’s largest producer of ternary cathode materials. To compensate for the product structure weakness dominated by ternary materials, it quickly entered the lithium iron phosphate track through acquisitions of Guizhou Xinren and a Shanghai-based company.
Previously, Ronbay Technology disclosed the “RB One-Step Process.” The company claims this technology can compress the traditional 15 steps required for lithium iron phosphate production into just 6 steps. The investment cost of the production line can be reduced by about 40%, and energy consumption during production can also be reduced by about 30%.
