Chinese electric vehicle manufacturer BYD has officially denied circulating online rumors suggesting that its much-anticipated solid-state battery technology would be introduced in the BYD Seal electric sedan.
The company clarified that reports claiming such specifications were inaccurate and emphasized that no official announcements had been made regarding the debut model or its technical details.
Unverified claims had recently gained traction online, suggesting that the BYD Seal could deliver an unprecedented 1,500-kilometer CLTC-rated range on just a 12-minute charge, allegedly powered by a 400 Wh/kg solid-state battery.
Some speculators had gone further, projecting a possible range of up to 1,875 kilometers. BYD’s public clarification directly addressed these exaggerated figures, stating that such information was unfounded and not supported by the company’s official channels.
Although BYD confirmed that the Seal sedan will not feature solid-state battery technology at this time, the company reaffirmed its long-term commitment to the innovation.
BYD’s Chief Technology Officer, Sun Huajun, had previously outlined a roadmap aiming for demonstration-level deployment of solid-state batteries by 2027.
According to the plan, mass-market production and integration are expected to follow after 2030. This timeline reflects the company’s cautious but strategic approach to a technology that remains in advanced research and development stages.
BYD has spent over a decade investing in solid-state battery research, making significant progress in recent years. In 2024, the company initiated extensive testing on 20Ah and 60Ah solid-state cells.
These tests reportedly delivered promising results in both energy density and fast-charging performance. Industry analysts have noted that, should progress continue at this pace, cost parity with current liquid lithium-ion batteries could be achieved by the end of the decade. However, BYD continues to stress that large-scale commercial production remains a few years away.
The company’s recent statement serves as a reminder of the importance of relying on official sources when tracking developments in the fast-changing electric vehicle industry.
While the BYD Seal will not launch with solid-state battery technology, BYD remains firmly positioned as a key innovator in the field. The company encourages both consumers and industry observers to wait for verified announcements regarding its battery technologies and product specifications.
