如何研發出兼具長續航與快充性能的電池，是汽車行業面臨的重大挑戰之一。在日本，豐田是對固態電池投入力度最大的企業之一，而固態電池恰好能夠實現這一目標：續航里程超1000公里，且充電時間更短。

但豐田並非獨自推進固態電池量產進程。除這家車企外，多家企業也憑藉自身技術與產業設施助力該目標實現。出光興產（Idemitsu Kosan）便是其中一家合作石油企業。該公司已與豐田在該領域合作多時，且啱啱宣佈建設一座固態電池電解質生產工廠。

這些高科技材料將專供豐田生產的電池使用。雙方目前已擁有兩座小型試驗設施，致力於新型電解質的研發並將其應用於固態電池。新工廠預計將於2027年底投產。

項目投產後，每年可生產數噸固態電解質，足以滿足豐田固態電池的生產需求。除上述石油企業外，豐田還與該領域其他企業展開合作。礦業企業住友金屬礦山（Sumitomo Metal Mining）也參與該項目，為產業聯盟提供高性能正極材料。

2028年實現1000公里續航

根據豐田規劃，首批固態電池預計2027年問世，續航里程可達1000公里，電量從10%充至80%僅需10分鐘。儘管第一代產品尚未投產，第二代固態電池的研發工作已同步推進，其續航里程將提升至1200公里，充電時間也有望進一步縮短，目前規劃的充電時長已具備極高實用性。

豐田並非唯一佈局該技術的企業。不久前，梅賽德斯-奔馳憑藉固態電池實現單次充電續航1200公里。與此同時，全新名爵4（MG 4）搭載半固態電池，該電池僅含5%液態電解質。該技術尚處起步階段，但有望成為電動出行行業的顛覆性變革力量。

A Japanese oil company is collaborating with Toyota to create solid-state batteries

Finding a solution to achievea battery that offers long battery life and allows for shorter charging times This is one of the major challenges facing the automotive industry. In Japan, Toyota is one of the companies investing most heavily in solid-state batteries, which allow precisely that: a storage capacity that enables a range of over 1.000 kilometres and short loading times.

But Toyota is not alone in this process of achievingmanufacture solid-state batteriesAlongside the car manufacturer, other companies lend their expertise and infrastructure to achieve these goals. One of these collaborating companies is the oil company. Idemitsu KosanThis company has been collaborating with Toyota in this area for some time now, and has just announced the creation of a production plant for electrolytes for solid-state batteries.

These high-tech elements will be dedicated to thebatteries produced by Toyota and already has two small-scale test facilities where they have been working to the development of new electrolytes which will be applied to these batteries. The new plant will be ready to start production by the end of 2027.

Once the project is underway, it will be possibleto manufacture several tons of these solid electrolytes each year, enough to meet the production needs of Toyota solid-state batteriesAlong with the oil company Toyota, it collaborates with other companies in the sector. The mining company Sumitomo Metal Mining It is also integrated into the project, offering the consortium high-performance cathode materials.

1.000 kilometers of range in 2028

According to Toyota's planning, it is expected thatThe first solid-state batteries will be ready by 2027These should offer a total range of 1.000 kilometers and their charging time from 10% to 80% would be 10 minutes. But although this first generation has not yet begun production, Work is already underway on a second oneThis would increase the range to 1.200 kilometers. Charging time could also be reduced, although quite practical times are already being discussed.

Toyota isn't the only company investing in this technology. Not long ago,Mercedes managed to travel 1.200 kilometers with a single charge from a solid-state battery. Meanwhile, the new MG 4 It uses a semi-solid-state battery, which uses only 5% liquid electrolyte. This technology is still in its early stages, but it could be a major game-changer for the electric mobility industry.
