ColdBlock Technologies Inc. Announces Sample Digestion Methods for Black Mass

With ColdBlock, samples up to 20g can be digested in under 30 minutes.

Niagara Falls, Ontario–(Newsfile Corp. – November 14, 2024) – ColdBlock^TM Technologies Inc. is advancing the use of its innovative digestion technology for applications in black mass testing and analysis. Black mass is a product of the battery recycling process – it is a concentrated, complex mixture of valuable metal oxides and compounds left after shredding and processing spent lithium-ion batteries.

The increasing global demand for electric vehicles, and other battery-operated devices, has led to a significant rise in the production of lithium-ion batteries. As these batteries reach end of life and are recycled, testing and analysis is critical to determine whether valuable metals such as lithium, nickel, manganese, and cobalt can be recovered.

The testing and analysis of black mass is critical to assess the quality and contents of the material, ensure efficient recovery of valuable metals, and optimize the subsequent refining process. Sample digestion is a vital step in the elemental analysis process, as it ensures that sample material is accurately, consistently, quickly and safely prepared for analysis.

ColdBlock is the first and only sample digestion technology that uses focused short-wave infrared heating and a cooling zone to dissolve solid sample matter into a solution for analysis. This allows for the digestion of a variety black mass samples to happen in minutes, and the contents to be assessed in a safe and simple process.

The ColdBlock R&D Lab has developed two new black mass digestion methods that deliver accurate results in under one hour. One of the most compelling outcomes is the ability to digest larger sample sizes – which is critical given the lack of homogeneity inherent in this sample type:

Lorie-Anne Doig, Director of Laboratory Services at ColdBlock explains the benefit of the larger sample sizes. “The contents of black mass tend to be inconsistent as they differ from source to source, given that there are many different approaches to battery recycling. The variability in particle size, morphology and distribution of metals adds to the challenge of obtaining a representative sample for analysis. Larger sample sizes ensure that more regions of the bulk material are included, thus reducing the risk of biased results. With ColdBlock, sample sizes of up to 20g can be digested efficiently. This is a significant advantage in black mass sample analysis.“
