Reply to comment by SGTLuxembourg in South Korean researchers say they have developed an anode-free lithium-ion battery that is 40% more energy dense than existing batteries and will enable EVs to travel 630km (390 miles) on a single charge. by lughnasadh

A lithium-free anode is someting completely different from a anode-free battery.

I just wanted to point out the ridiculousness of what is written. You are absolutely correct in the explanation, but their wording is still wrong.

Yeah definitely, in the research community I am a part of we try to say “lithium-free” rather than anode-free but the later is more common in the literature. Even then it isn’t lithium free always just at assembly (and theoretically at 100% discharge if everything is behaving ideally).
