Why the electrical autonomy revolution is not for tomorrow

It is a dream that manufacturers have fueled for almost ten years: that of a battery capable of offering 1. Therefore, 000 km of autonomy, to recharge in ten minutes, all without risk. Consequently, The so -called “solid” battery checks all the boxes of the electric Grail. Nevertheless, At least on paper. Furthermore, Because in 2025. Similarly, mass production always seems out of reachdespite the announcements made by many manufacturers, from Toyota to BMW via Stellantis, Saic, Byd or Chery. For example, The observation is now shared by the main players in the sector. Nevertheless, During the last China Automobile Forum. In addition, Wang Fang, chief scientist of China Automotive Technology Research Center, summed up the state of technology in Four problems that are still to be resolved: still unstable ionic channels, too complex production processes, difficulties in safety and current impossibility of why electrical autonomy revolution not manufacturing on a large scale. Furthermore, Suffice to say that the calendar of 2026-2027. Furthermore, often brandished in the press releases, is even more optimistic than the realistic roadmap.

Technological delay … and industrial discomfort – Why electrical autonomy revolution not

Already in 2023, several votes called for caution. Professor Jean-Marie Tarascon. specializing in the chemistry of the solid, then evoked A form of panic among manufacturers: fear of missing the turn, craze for startups like quantumscape or solid power, but no technical certainty on the outcome of projects. Result: many hybrid initiatives, halfway between liquid and solid batteries, abusively qualified as “all solid” in communication. In 2024, the Catl batteries giant even threw a pavement into the pond. His boss Robin Zeng said that Solid batteries posed security problems, lifespan … and that they were not viable as it is. An incomparable position. emanating from the world’s number one of batteries, which prefers to bet on why electrical autonomy revolution not alternative technologies such as sodium-ion or semi-solid.

The market is evolving, the revolution is moving away

For its part, the market context no longer pushes the emergency. Liquid lithium-ion batteries have made rapid progress: better density, better longevity, faster load. Byd this year presented a platform capable of recharging 400 km of autonomy in five minutes. Nio has generalized its battery exchange stations. Zeekr and Huawei deploy ultra-powerful loads up to why electrical autonomy revolution not 1.5 MW, far beyond what would be able to collect serial cars. In parallel, hybrid vehicles, including extended autonomy versions, are growing strongly (+31.5 % in the first half of China). Under these conditions. the solid battery no longer appears as a necessary rupture, but as a premium long -term product, the cost of which would be three times higher in KWH will limit use to high -end vehicles for several years. According to the most credible estimates, the industrial rocking will not intervene before 2030, or even beyond.

No technological miracle in sight

The hope of a sudden tilting towards electric cars capable of competing with thermal on all levels (autonomy. recharging, price) thanks to the solid batteries therefore moves away. Production announcements for 2026-2027 are maintained by some so as not to cool investors. markets… But in the field, the manufacturers are advancing cautiously. Will byd manage to set why electrical autonomy revolution not up his solid battery for his first tests in 2027. and keep his mass production promise for 2030? BMW. which has already driven its first prototype this year, an i7, with a solid battery, will he be one of the first to revolutionize electric with this technology, “before 2030” as announced? Difficult to say.
