Chinese language automaker BYD has formally denied latest reviews claiming that its extremely anticipated solid-state battery know-how shall be put in within the Seal electrical sedan. The corporate clarified that the web claims are inaccurate: “The knowledge is fake. The whole lot stays unsure. The primary mannequin and its specs haven’t been formally introduced.”
The hearsay originated from speculative reviews suggesting that BYD’s Seal mannequin would debut the brand new battery, that includes a record-breaking power density of 400 Wh/kg and enabling a CLTC-rated vary of as much as 1,500 kilometres (932 miles) from a 12-minute cost. Some reviews even cited a complete vary of 1,875 kilometres (1,165 miles) based mostly on partial cost estimates. Nonetheless, BYD’s newest assertion clarifies that the corporate has not confirmed these particulars.
These developments observe BYD CTO Solar Huajun’s remarks earlier this yr, outlining the corporate’s timeline for solid-state battery commercialisation. On the 2025 China Stable-State Battery Innovation Growth Summit, Solar confirmed that BYD had begun putting in prototype solid-state packs into Seal fashions for street testing. In line with Solar, demonstration-scale deployment is predicted round 2027, with mass-market adoption focused for post-2030 as soon as manufacturing scaling is achieved.
Internally, BYD has spent greater than a decade creating solid-state battery know-how. The agency started testing 20Ah and 60Ah solid-state cells final yr and reportedly achieved key breakthroughs in power density and fast-charging functionality. Regardless of promising early check outcomes, together with potential parity in value with present liquid lithium-ion batteries by the tip of the last decade, BYD has emphasised that mass manufacturing remains to be years away.
Whereas BYD’s denial tempers short-term expectations, its ongoing check program and long-term roadmap sign robust intent to steer the following wave of battery innovation. For now, the general public ought to cautiously deal with any model-specific claims about BYD’s solid-state rollout until confirmed by the corporate.
