Solarite Completes Development of Secondary Battery Recycling Pretreatment Equipment Technology Using Dry Discharge

Solarite Co., Ltd. announced that it has completed the development of secondary battery recycling pretreatment equipment technology for the safe disposal of used batteries.

Solarite's 'Multi-Stage Dry Discharge (MDD) Equipment' is a discharge equipment technology for the pretreatment stage of recycling used batteries. It is an automated system equipped with everything from the collection (transportation and storage) of used batteries (waste batteries) to dry discharge and post-management. Notably, it features a disablement technology that consumes 99.99% of the battery's remaining charge, attracting attention.

As the collection rate of waste batteries increases, the existing wet discharge method has faced limitations in large-capacity discharge due to environmental pollution and treatment costs caused by wastewater and toxic substances, as well as long processing times of at least 48 hours for wet and drying processes, resulting in insufficient safety and economic efficiency. The risk of fire and explosion due to residual energy after wet discharge has raised the need for a safe processing environment, making it urgent to find solutions in line with the expanding secondary battery recycling market.

Recently, based on various systems for creating sustainable social value such as K-RE100, ESG, carbon neutrality, and RFS, interest in energy recovery and regeneration has expanded. In this context, Solarite developed the 'Multi-Stage Dry Discharge (MDD) Equipment,' a solution for the energy regeneration industry that maximizes the utilization of high value-added resources.

Solarite's 'Multi-Stage Dry Discharge Equipment' is eco-friendly as it does not generate separate waste, and it ensures the safety of batteries with high electrical risks by enabling control of discharge speed and current. Battery disablement was successfully achieved through crushing and grinding demonstrations.

Additionally, efficiency and economic feasibility were achieved by extracting cells from disabled batteries, and the application of an automated system from collection to disposal eliminated unnecessary transfer and transportation processes during the process, realizing cost reduction.

Regarding this, Solarite CEO Kim Wol-Young stated, “We will focus on expanding the pretreatment area of secondary battery recycling through high-efficiency technology and high value-added resource utilization, and respond to the demand for this technology by playing a leading role in facility establishment and operation.”

Solarite added, “This equipment technology is expected to contribute to stabilizing the recycling industry, has lower investment rates compared to wet processes, and higher recovery rates, leading to qualitative growth in the resource discovery industry in the future. It is anticipated to establish itself as a new industrial sector in secondary battery recycling and contribute to realizing a nation that leads the secondary battery industry in the global market.”
