在2025年11 月 6 日特斯拉投資者日上,有投資者聚焦特斯拉干法電極的進展情況提問。馬斯克坦言干法陰極(正極)量產仍存在較多需要解決的問題,但認為該路線最終會成功。目前特斯拉已新建多條電池生產線,計劃啟動更大規模量產線。

以下是采訪原文:
Q:You also talked about the battery being a product, I saw the dry cathode method and so forth, and I wanted to know the progress in that,and also would obviously be working on that in the future? Production line?
提問者:你也提到電池本身就是一款產品,我了解到干法陰極(干法正極)等技術,我想知道這方面的進展,以及未來是否還會繼續推進這項技術?生產線的情況?
Elon Musk: Yeah, I guess the dry cathode, that''s turned out to be a lot harder than we thought. So,I mean it ,It does look like it''s gonna be successful,and it will have some cost advantage, relative to wet cathode. Um,but if I had to wind the clock back, I would probably have gone with wet cathode instead of dry cathode.
埃隆·馬斯克:對,我想干法陰極的實際難度比我們預想的要大得多。不過,這項技術最終應該會成功,而且它會有一定的成本優勢相較于濕法陰極。但如果能重來一次,我可能會選擇濕法陰極而非干法陰極。
Elon Musk: Cos it just turned out to be a lot harder to make it uh,you know ,high volume,capable of high volume production. With super high reliability.
埃隆·馬斯克:因為要實現它的難度遠比預想大得多,你知道,高產量,具備規模化量產。同時保證超高可靠性。
Elon Musk: Um,so yeah. But we will be scaling up battery cell production at Tesla.,and looking for cell production from our suppliers as well. Because we''re gonna be ramping up production very dramatically at Tesla.
埃隆·馬斯克:所以,對。不過,我們特斯拉后續會擴大電池電芯的生產,同時也會尋求我們的供應商提供電芯生產。因為我們特斯拉將會大幅提升生產。
干法電極技術作為特斯拉電池技術的一大亮點,一直被行業所關注,干法電極技術沒有NMP溶劑,能提高能量密度,降低能耗,減少設備投入成本等。但一項新技術從研發到量產面臨較多需要解決的現實問題。如正極材料適應性問題、干法工藝問題、生產設備問題,PTFE粘結劑問題等。干法正極的技術突破,并非單一企業能獨立完成的難題,需要全球鋰電行業從業者共同攻關,打破技術瓶頸。中國作為全球鋰電產業的龍頭,具有最完善的產業鏈及最大出貨量,干法電極技術給中國鋰電企業帶來了機遇與挑戰。
