1. 1. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals

   Författare :Safoura Babanejad; Hesham Ahmed; Charlotte Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; black mass; Recycling; Pyrometallurgy; modeling; Process Metallurgy; Processmetallurgi;

   Sammanfattning : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). LÄS MER

3. 2. Environmental Assessment of Battery Systems: Critical Issues for Established and Emerging Technologies

   Författare :Carl Johan Rydh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaic cells; battery; environmental indicators; substance flow analysis; energy analysis; metal recycling; energy efficiency; materials management; rechargeable; life cycle assessment; renewable energy;

   Sammanfattning : Energy and material flows associated with portable and industrial rechargeable batteries have been quantified in a life-cycle perspective, as guidance for development of battery systems. The study included portable batteries based on nickel-cadmium, nickel-metal hydride and lithium-ion. LÄS MER

4. 3. Sustainable recycling of Li-ion batteries

   Författare :Jędrzej Piątek; Adam Slabon; Tetyana Budnyak; Reza Younesi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; batteries; recycling; metal recovery; adsorption; electrochemistry; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

5. 4. Exploring cellulose as a biomacromolecule for enhanced battery metal ion recovery/recycling

   Författare :Billy W. Hoogendoorn; Richard Olsson; Yuanyuan Li; Mikael S. Hedenqvist; Aji Mathew; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomacromolecules; Nanocellulose; metal oxide nanoparticle synthesis; electrodeposition; battery recycling; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The research focused on the effects of integrating nanocellulose in the solidification of metal ions into metal oxide particles or metallic electrodeposits.  Firstly, the cellulose was isolated as highly crystalline ca. 15-25 nm thick and 500 nm long fibers from bacterial cellulose using acid hydrolysis and had a negative surface charge.

7. 5. Recycling of nickel metal hydride (NiMH) batteries; Characterization and recovery of nickel, AB5 alloy and cobalt

   Författare :Filip Holmberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; nickel; AB5 alloy; cobalt; NiMH battery; hydrogen storage alloy; leaching;

   Sammanfattning : Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. LÄS MER
