Molie Quantum Energy Corporation battery plant (hereinafter referred to as the “MQE battery plant”) belongs to the battery manufacturing industry. The plant is currently shut down following a fire that occurred on July 14th when semi-finished batteries under testing ignited.
The fire caused concern and worry among nearby residents who were anxious about the potential for trace hydrogen fluoride (HF) production and impact on air quality. We understand the inconvenience and distress the fire at the MQE battery plant has caused the local community and environment. To demonstrate our firm commitment to environmental sustainability, the MQE battery plant voluntarily commissioned a third-party unit to conduct testing and release reports on key environmental indicators from August to December for the community’s reference. All subsequent waste clearance operations will be in compliance with regulations and conducted after securing approval from the public sector. Furthermore, the company will fully communicate with local village chiefs beforehand. We are committed to rebuilding mutual trust and continuously ensuring environmental safety through concrete actions.
Following the release of the August environmental monitoring results in early September 2025, the MQE battery plant continues to release the September environmental monitoring report in early October. The latest data shows that the air quality around the plant perimeter and the stormwater runoff both comply with national standards, indicating no impact on the surrounding environment.
