Advanced Automotive Battery Conference: New Battery Chemistries
Advanced Automotive Battery Conference (AABC) will be held on June 13-15 in Mainz, Germany. The conference program consists of four symposiums, including new materials chemistry, engineering methods like battery design and safety, recycling, and lead-acid battery. Four conferences also will be held about hybrid and electric vehicles, battery raw materials, and heavy-duty applications. So reviewing the technical background of present speakers and companies with specialized industrial experience can give useful information about the event. The identifing the approaches of companies speaking at the new materials chemistry symposium is the subject of this article.
Two speakers will talk about liquid electrolytes as a forgotten component of lithium-ion batteries, one of them is representing Koura Company. This company has introduced Koflyte®, a fluorine-containing liquid electrolyte based on polyethers, in 2021. Koura also acquired Silatronix, a battery electrolyte start-up, to develop its electrolyte product line. Koflyte has received a 3.1 M$ award from the U.S. Department of Energy for improving lifetime and safety of battery using this electrolyte.
Other features of this technology include high voltage and superior thermal stability and modified SEI layer formation on the active material. Silatronix's technology includes six patents protected in the U.S. and Europe. The second speaker is from E-Lyte Innovations, a research firm on phosphorus-based electrolyte additives used in nickel and cobalt-based cathodes. BMW and CATL jointly patented the technology.
In addition, Solvay as a leader among electrolyte manufacturer will introduce EnerGain® fluorine-based electrolyte used in batteries containing Nickel-rich cathode and silicon anode.
BASF is another company present at the conference, one of the top suppliers of cathode materials in the world, with at least 200 patents on this type of material. A speaker from Umicore will also introduce manganese-rich cathodes with high capacity, and competitive price with iron phosphate cathodes.
High-capacity anodes are another focus of this symposium. Speakers from LeydenJar, Helmholtz Institute and, Group14 Technologies will discuss topics such as pre-processing of silicon with lithium (pre-lithiation) and chemical vapor deposition (CVD) as a method of preparing high-purity silicon nanostructures that are also binder-Free. In addition, Enovix, will introduce 3D silicon anodes developed by semi-conductors synthesis method. Nanoramics Laboratory will speak about silicon anode which can use aqueous medium in its slurry process, without NMP as a solvent.
Other leading technologies of the event is solid-state electrolytes used in lithium-ion batteries. The speakers mainly focus on oxide-based inorganic ceramics and polymeric solid electrolytes for electric vehicle applications. Factorial Energy, with 34 patents, will probably present its polymeric electrolyte.
