      Submission Statement: The heart of the POSTECH innovation lies in its ability to guide lithium ions during the charging process using an external magnetic field. The system targets a specific type of anode, ferromagnetic manganese ferrite conversion-type, which reacts when lithium is inserted into its structure. This reaction produces metallic nanoparticles that become ferromagnetic.

      When exposed to the magnetic field, these particles align like miniature magnets within the battery’s electrode. As explained by the researchers in Energy & Environmental Science, this internal magnetic alignment helps prevent lithium ions from clustering in specific areas. Instead, it spreads them more evenly across the surface, reducing the chance of irregular deposition, which often leads to the hazardous formation of dendrites.

      The Lorentz force, the physical effect that acts on charged particles moving through a magnetic field, plays a key role in this process. According to POSTECH, it further disperses lithium ions, maintaining a smooth and uniform lithium layer during cycling.

      I’m pretty sure both uneven distribution of ions and dendrite formations are two of the problems that so many of the „AMAZING NEW MIRACLE BATTERY“ items published lack, and this one actually sounds promising.

      Okay, magnetic fields. Doesn’t say anything about how long it will take the tech to get to market. My question is how are Na batteries going to change the market in the meantime? Seems like we’re moving to a lithium-free battery market, already starting to take shape.

      How does this compare with Quantumscape’s solid state cell lithium battery?

      So first we moon the fire risk with a lithium anode then decrease it with a magnetic field. Not sure I want to own that. Please find another solution that doesn’t start with high thermal runaway risk that you then increase before applying the band aid.
