Case Study

Application of Dimethylpropiothetin in the Green Recycling of Spent Lithium-Ion Batteries

Shi, Huiying, et al. Hydrometallurgy 237 (2025): 106551.

This work evaluated dimethylpropiothetin (DMPT) as a green, high-efficiency leaching reagent for recovering lithium (Li), nickel (Ni), cobalt (Co) and manganese (Mn) from spent ternary lithium-ion battery (LIB) cathode materials. Leaching strategy: Use DMPT (industrial-grade) in an aqueous leaching protocol applied to spent ternary cathode material. The work explicitly emphasized avoiding strong acids, bases or added reducing agents-contrast to many conventional hydrometallurgical methods.
Key Performance
· High leaching yields: Under the optimized conditions reported in the study, leaching efficiencies reached Li 98.7 %, Ni 97.2 %, Co 97.8 % and Mn 98.3 %.
· Mechanistic insight: The authors attribute the strong leaching performance to synergistic action involving DMPT's carboxyl functional groups together with chloride ions associated with the molecule-promoting effective dissolution/complexation of the target metal species.
· Product characterization: The use of XRD, SEM and XPS analyses to identify leaching products and to confirm surface level interactions between DMPT and cathode materials, supporting interpretation of the chemical reactions taking place during leaching.
· Green metrics: The DMPT protocol reportedly does away with the need for strong mineral acids, alkaline reagents, or external reducing agents-minimizing the potential for secondary pollution common to traditional hydrometallurgy.

Dimethylpropiothetin Feed Attractant for Improving Growth, Digestion and Serum Indices in Hucho taimen

Wang ChangAn, et al. Journal Board of Animal Husbandry and Feed Science, (2012): 236-240.

The trial compared four attractants-DMPT, trimethylamine oxide (TMAO), betaine, and sodium-5'-inosinate-against a control to determine effects on feed intake, growth performance, body composition, digestive enzyme activity and serum indices in Hucho taimen. Fish receiving 0.20% DMPT in the diet for 56 days showed statistically significant improvements in feed intake-related performance (weight gain rate, specific growth rate), higher whole-body crude protein, enhanced digestive enzyme activities, and elevated serum protein fractions (total protein, albumin and globulin). These outcomes indicate DMPT's potential as a small-dose feed additive to support growth, nutrient utilization and protein-related serum markers in cold-water aquaculture species.
Methodology: A controlled feeding trial was conducted over 56 days using juvenile Hucho taimen with an initial average weight of 9.39±0.26 grams. The fish were raised in a flow-through water system with tightly controlled temperature (9.3°C to 14.2°C) and dissolved oxygen levels (above 8.0 mg/L). The study included one control group (basal diet) and four treatment groups. Each diet was randomly assigned to triplicate tanks, each containing 50 fish. The treatment groups were supplemented with 0.2% DMPT, 0.2% trimethylamine oxide, 0.2% betaine, or 0.05% sodium-5'-inosinate, respectively.
Comparative Notes: TMAO and betaine at 0.20% also improved several growth and biochemical endpoints (e.g., reduced body lipid with some supplements), while sodium-5'-inosinate at 0.05% produced no growth or digestive changes but increased complement factors. These comparative outcomes contextualize DMPT's profile among attractant candidates.
