馬斯克預告:能量密度提升 60% 的新型電池最快三年後量產,伴隨長效循環壽命
正當大家期待 9 月 23 日凌晨 04:30 的特斯拉股東大會與電池日活動時,馬斯克已經搶
先在網上爆了料,說特斯拉很快就會達到電池能量提升 60%。
特斯拉電池日新消息!股東大會後接力登場,9/23 凌晨四點半直播看這裡!
(原文網址:https://bit.ly/3hvnBFs)
馬斯克是在回覆網友時更新了這個新型電池的量產時間表,60% 則是我們自行計算出來的
,但根據他的原話,再與目前特斯拉電動車 Model 3 所採用的 21700 電池的 247Wh/kg
能量密度相比,意思確實是如此:
「具備 400Wh/kg 與長效充放循環壽命的電池距離量產已經不遠了 (不是只在實驗室測試
),也許三到四年間就會出現。」

如果關心特斯拉的朋友,對這次馬斯克提到的數據一定很耳熟,因為 400Wh/kg 是一個分
界點,馬斯克之前曾在「城市電動飛機」的議題中提出,也是日前特斯拉加拿大電池研究
團隊 Jeff Dahn 教授最新發表的論文中所提到的能量密度目標。
特斯拉的無陽極鋰電池新技術有多強?能量密度大幅成長,連電動飛機都能用!

特斯拉「無陽極鋰金屬電池」專利新曝光:價格更低、能量密度更高
(原文網址:https://bit.ly/3aYuFbi)
在 Dahn 最新發布的研究報告指其無陽極電池技術已經大幅提升電池能量密度,目前已經
進展到 360Wh/kg,幾乎可以用做電動飛機使用。不過這項技術仍需更多的循環次數測試
,要達到商用標準,必須將循環壽命拉高到 800 至 1,000 次才行,報告中也沒有提到任
何關於成本控制與推出時程的訊息。
馬斯克這次的表態,可說是完全呼應了 Dahn 團隊進行中的計畫,儘管這不會是九月電池
日上就會推出的技術,但「最快 3 至 4 年」這個首次透露的時間點也非常讓人期待,因
為假使進展順利,幾年之後的特斯拉就會具有比現在高出 60% 的電池能量密度技術,絕
對會是電動車 (電動飛機?) 產業的一記重磅轟炸。
在上週,與特斯拉合資電池工廠的日本松下也宣布加碼投資一億美元擴廠,將自明年起提
升一成電池產能,九月起生產的新電池都已提升 5% 能量密度,同時也會和特斯拉持續研
發新技術,預計在五年內將松下電池能量密度提升 20% 以上。

特斯拉又要跑更遠了!松下豪語電池將提升 20% 能量密度,無鈷電池最快二年後誕生

心得/說明:(30字以上)
老馬總是耐不住,還沒等股東會就先爆料
這消息跟之前傳出的差不多
不過老馬給了個 3~4 年的量產時間點
這樣看起來特斯拉的電池技術並沒有想像中的大幅領先啊...
我以為現在的股價代表明年就可以量產屌打所有車廠...
