Solid Wastes from Geothermal Energy Production and Implications for Direct Lithium Extraction
Published on 2025-03-10 by William T. Stringfellow, Mary Kay Camarillo @MDPI
Abstract: Direct lithium extraction (DLE) of brines after geothermal power production offers opportunities to produce environmentally benign “green” lithium; however, some environmental impact is inevitable. We examined solid waste production at geothermal power plants in southern California that are also locations for planned DLE facilities. Currently, the geothermal plants in this region produce approximately 79,800 metric tons (wet weight) per year of solid waste, which repr[...]
Our summary: Examination of solid waste production at geothermal power plants in southern California reveals significant amounts of waste generated, including hazardous waste. The production of lithium through direct extraction from brines poses environmental challenges due to the need to remove various metals and minerals from the brine. Analysis of brine chemistry is essential for understanding and mitigating the potential impacts of solid waste generation in lithium production.

Rapid Synthesis of Honeycomb-Structured FeP2@NHC for High-Rate and Durable Lithium Storage
Published on 2025-03-10 by Junjie Shao, Xiaodong Wang, Houhua Ceng, Lan Hu, Zhean Su @MDPI
Abstract: The concurrent preservation of structural integrity and improvement of electrical conductivity in FeP2 anodes presents a persistent challenge. Herein, FeP2 nanoparticles embedded within a 3D N-doped honeycomb-like carbon framework composite (FeP2@NHC) are synthesized through a phosphorization process with a honeycomb-like Fe3C@NHC as a precursor. The in situ incorporation of FeP2 nanoparticles into the 3D carbon matrix effectively restrains the aggregation, pulverization, and stripping of materi[...]
Our summary: Rapid synthesis of FeP2@NHC for high-rate and durable lithium storage, preservation of structural integrity and improvement of electrical conductivity, in situ incorporation of FeP2 nanoparticles into 3D carbon matrix, superior electrochemical performance achieved.
