This young company hopes to begin producing its Gemini pack at a new 20-gigawatt-hour U.S. manufacturing plant in 2026, founder and Chief Executive Mujeeb Ijaz said in an interview.
Other battery companies are developing anode-free designs, but ONE’s Gemini battery appears to be unique in that it uses cells with two different cell chemistries, including one for everyday driving and a second to extend driving range on longer trips.
The secret sauce is in Gemini’s large-format range-extender cells. While the standard cells use relatively conventional lithium iron phosphate cathodes and graphite anodes, the range-extender cells are anode-free, which eliminates the use of graphite and anode-making equipment.
The cathodes are designed to use a unique blend of lithium and manganese and a much lower percentage of nickel, while eliminating cobalt, according to Ijaz.
While the lithium-rich manganese nickel cathodes are still being refined, the current version of the range-extender cells uses cathodes made of nickel, cobalt and manganese.
ONE's Gemini battery will be displayed Sept. 13-15 at The Battery Show in Novi, Michigan.

(路透社)- 總部位於密歇根州的初創公司 Our Next Energy (ONE) 週二表示, 將推出了一種新的無正極電池組,旨在將電池成本降低多達 50%,同時提供長達 600 英里(965 公里)的續駛能力。
創始人兼首席執行官 Mujeeb Ijaz 在接受採訪時表示,這家年輕的公司希望於 2026 年在美國新的 20千兆瓦/時製造工廠開始生產 Gemini 電池組。
其他電池公司正在開發無正極設計,但 ONE 的 Gemini 電池似乎是獨一無二的,因為它使用具有兩種不同電池化學成分的電池,其中一種用於日常駕駛,另一種用於延長長途旅行的續航能力。
秘訣在於 Gemini 的大格式增程電池。雖然標準電池使用相對傳統的磷酸鐵鋰負極和石墨正極,但增程電池沒有正極,因此無需使用石墨和製造正極的設備。
根據 Ijaz 的說法,負極設計是一種使用鋰和錳的獨特混合物, 以及用少了鎳,並同時不使用鈷。
“不使用鎳和鈷一直是我的長期願望”, Ijaz 談到目前大多數電動汽車電池中這兩種關鍵負極材料,它們比錳等常見材料更昂貴且更不可持續。
雖然高成份鋰錳鎳負極仍在提煉中,但當前版本的增程電池使用由鎳、鈷和錳製成的負極。
ONE 表示,通過消除這些電池中的正極,它可以將批量生產的電池成本降低 50 美元/千瓦/時 - 與目前估計的100 至 110 美元每千瓦/時的成本相比,可節省大量成本。
Ijaz 說: “我們的目標是在 2026 年推出 Gemini 電池,鈷含量為零,鎳含量不超過 26%,使用錳作為主要負極的材料” 。
ONE 的 Gemini 電池將於 9 月 13 日至 15 日在密歇根州諾維的電池展上展出。
So, a Michigan-based startup Our
Next Energy has unveiled a new anode-free battery pack designed to slash cell
cost as much as 50% while delivering up to 600 miles (965 km) of driving range.
This is good news for the electric car makers.
