Chinese battery giant CATL has begun trial production at its planned 100 GWh cell factory in Győr, Hungary. The pilot line, which started operations on 19 September, is focused on a next‑generation nickel‑cobalt‑manganese (NCM 811) chemistry that promises an energy density of 260 Wh kg⁻¹ and a 20 % cost reduction versus the company’s current NCM 622 cells.

The Hungarian site is part of CATL’s “European Battery Belt” strategy, intended to diversify supply away from China and to meet the EU’s forthcoming battery‑cell regulation, which mandates a minimum 30 % recycled‑content share by 2030. The trial line will produce up to 5 GWh of cells per year while the full‑scale plant, slated for commercial operation in 2028, will host 20 production lines and target an annual capacity of 100 GWh.

Key technical goals include a 0.1 % defect rate, a 1,500‑cycle life at 80 % depth‑of‑discharge, and a fast‑charge capability of 0.5 C (≈ 1 hour to 80 % state‑of‑charge). CATL plans to supply the first batches to European OEMs developing high‑energy EVs and to several grid‑scale storage projects under the EU’s “Fit for 55” plan.

The move also signals a shift in the global battery supply chain: by locating production in Central Europe, CATL can reduce logistics costs, shorten lead times, and sidestep potential tariffs. Analysts at BloombergNEF estimate that the Hungarian plant could shave €200 million off the cost of a 75 kWh EV pack by 2030, accelerating the price parity between EVs and internal‑combustion cars.

The trial phase will run for six months, after which CATL will publish performance data and begin the certification process with the European Battery Alliance. If the targets are met, the plant could become a template for other Asian manufacturers eyeing Europe, intensifying competition with local players such as Northvolt and SK On.

Li Auto, the Chinese premium EV maker best known for its extended‑range plug‑in hybrids, disclosed a concrete rollout schedule for its solid‑state battery (SSB) program. In a briefing on 20 September, the company announced that limited‑edition models equipped with prototype SSB packs will enter pilot production in late 2027, with a broader market launch expected in 2028.

The announced SSB cells use a sulfide‑based solid electrolyte and a high‑nickel cathode, delivering a projected 350 Wh kg⁻¹ gravimetric energy density—roughly 30 % higher than Li Auto’s current lithium‑ion packs. The cells are also rated for 2,000 full cycles at 80 % depth‑of‑discharge, and they can be charged to 80 % in under 10 minutes at a 1 C rate, thanks to the solid electrolyte’s high ionic conductivity.

Li Auto’s timeline reflects a cautious “step‑wise” approach: the first SSB‑powered vehicle will be a premium SUV that retains the brand’s existing platform, allowing the company to validate integration, thermal management, and safety systems without a full redesign. Production will be limited to 5,000 units in 2027, primarily for fleet customers and early adopters in Tier‑1 Chinese cities.

The company highlighted that its solid‑state effort is backed by a joint venture with a Japanese solid‑electrolyte specialist, which supplies the sulfide material and co‑develops the cell architecture. Li Auto also plans to build a dedicated SSB cell line at its Xi’an plant, targeting an annual capacity of 10 GWh by 2030.

Industry observers note that Li Auto’s timeline is more aggressive than most rivals, many of which still list 2029‑30 as the earliest commercial SSB date. If Li Auto can meet its milestones, it could gain a first‑mover advantage in the Chinese premium EV segment, where range anxiety and fast‑charging remain key purchase drivers. The move also aligns with China’s “dual‑carbon” goals, as solid‑state batteries promise higher safety and longer lifespans, reducing the need for frequent pack replacements.

The UK Department for Transport unveiled a £350 million programme to replace diesel multiple units on several regional lines in northern England with battery‑electric trains (BETs). The first batch, scheduled for delivery in 2027, will consist of 30 kWh lithium‑ion battery packs mounted under the floor of new three‑car units built by a consortium led by Alstom and Hitachi.

Each BET will have a range of up to 120 km on battery alone, sufficient for typical branch‑line services that currently rely on diesel. The trains will recharge at terminal stations equipped with 1 MW rapid‑charge stations, enabling a full charge in under 15 minutes. The battery chemistry is a high‑nickel NMC 811 formulation, chosen for its balance of energy density (≈ 250 Wh kg⁻¹) and cycle life (≈ 2,500 cycles at 80 % depth‑of‑discharge).

The programme is part of the UK’s broader “Decarbonise Rail” strategy, which aims to eliminate diesel traction on the national network by 2040. By focusing on battery‑electric solutions for non‑electrified routes, the government avoids the high capital cost of full overhead line equipment while still delivering zero‑emission service.

Beyond emissions reductions, the BET rollout is expected to generate up to 1,200 jobs across manufacturing, installation, and maintenance, with a significant portion of the supply chain sourced from UK firms. The Department for Transport also announced a £50 million research fund to explore next‑generation solid‑state batteries for rail, targeting a 30 % weight reduction and a 40 % increase in range by the early 2030s.

Industry analysts see the UK move as a testbed for similar deployments across Europe, where many regional networks face the “electrification gap.” If the BETs meet performance targets, they could accelerate the shift away from diesel on lines where full electrification is economically unviable, setting a precedent for other countries with extensive secondary rail networks.
