BYD targets 2027 for limited solid-state battery production after key breakthroughs
By Eve
BYD confirmed to investors on 9 February 2026 that it expects to begin producing sulfide-based solid-state EV batteries in 2027 in limited batches, following breakthroughs in battery life and fast charging. The company's battery CTO Sun Huajun stated the first two years will serve as a demonstration phase with limited production, with mass production planned toward the end of the decade. BYD is advancing sulfide electrolytes that promise superior conductivity, safety and significantly higher energy density compared to traditional liquid lithium-ion batteries.
Why it matters
Solid-state batteries with faster charging and higher energy density could reshape EV infrastructure requirements and charging-site economics from 2027 onward. CPOs and procurement teams should monitor BYD's timeline as the technology may influence future charging-power specifications and site-design standards once mass production begins later in the decade.

Leapmotor B03X launches in Australia from $29,990, undercutting BYD Atto 2
Chinese EV maker Leapmotor will launch its B03X electric SUV in Australia in November 2025, priced from $29,990 drive away, below the 2026 BYD Atto 2 Dynamic. The B03X Style offers 292 km WLTP range from a 39.8 kWh LFP battery and 130 kW motor, while the Design LR variant extends range to 382 km with a 53 kWh battery and 145 kW motor. Both variants support DC fast charging at up to 100 kW and 133 kW respectively, charging from 30 to 80 per cent in around 16 minutes, and include 3.3 kW vehicle to load capability.
Why it matters
The sub $30,000 price point and fast charging capability may accelerate demand for home and workplace charging infrastructure in Australia's small SUV segment. Fleet operators and charging network planners should monitor uptake of this model as it competes directly with BYD in the budget EV market.
Suzuki launches e SKY mini EV at $13,500 with BYD batteries, undercutting BYD's own Racco
Suzuki will launch the e SKY, its first electric kei car, on 16 November at around 2.12 million yen ($13,500), narrowly undercutting BYD's Racco EV at 2.145 million yen ($13,600) to become Japan's cheapest mini EV, according to Nikkei. The e SKY offers a WLTC range of up to 310 km (192 miles) and uses lithium iron phosphate batteries supplied by BYD's battery unit. With potential government subsidies of 568,000 yen, the e SKY could cost about the same as Suzuki's petrol Spacia, which starts at 1.53 million yen (slightly under $10,000).
Why it matters
Ultra-low-cost EVs like the e SKY signal intensifying price competition in Japan's kei segment, where affordability and subsidy eligibility will shape fleet and consumer adoption. Procurement teams evaluating light commercial or urban fleets should monitor whether similar pricing and BYD battery partnerships emerge in other markets.
Tesla and Chinese brands lead UK electric car sales in record breaking September
More than 99,000 new electric cars were sold in the UK in September, alongside almost 5,000 zero emission vans, following the introduction of the new 76 number plate. Tesla led the market with a combined 15,875 sales from its Model 3 and Model Y, while several Chinese brands also saw a surge in demand. The figures were reported by GB News.
Why it matters
Record monthly EV registrations of this scale signal accelerating charging demand across the UK, and the dominance of Tesla and Chinese brands shapes which connector standards, payment integrations and co location partnerships CPOs and site hosts should prioritise.
