Svolt begins mass production of 100 kWh Dragon Armor semi-solid battery pack in Changzhou

First mass-produced semi-solid packs leave the Changzhou line

Svolt Energy announced on Monday, 26 October 2026, that the first batch of mass-produced 100 kWh Dragon Armor semi-solid fast-charging battery packs had rolled off its production line in Changzhou, Jiangsu province. CnEVPost reports the milestone was disclosed in a Weibo post, with an accompanying video in which chairman and CEO Yang Hongxin described the pack as a step in commercialising the technology. ²

CarNewsChina likewise reports that Svolt officials confirmed the first 'Dragon Armor' hybrid semi-solid battery had come off the line in Changzhou, and that company representatives described semi-solid packs with ternary chemistries as a long-term technological path. The pack is described as semi-solid or liquid-solid in China, using both liquid and solid electrolytes to transport ions, unlike all-solid-state cells that rely entirely on solid electrolytes. ¹⁵

No customer vehicle has been named. CnEVPost notes Yang said in the video that the battery pack had secured nominations from multiple customers, with the vehicles using it to be revealed soon. CarNewsChina's own expectation is that the GWM Wey V8X BEV could be among the first to adopt the pack, but that is the publication's forecast rather than a confirmed Svolt announcement. No Australian vehicle or availability plan has been announced. ¹²

Claimed charging, durability and safety figures remain unverified

Svolt claims the pack is built on a 900V high-voltage system with liquid cooling on both the top and bottom of the housing, supporting 6C fast charging that the company says can add 500 km of range in 12 minutes. CnEVPost notes these performance figures were disclosed by the company and that the announcement did not specify the test conditions used for the range-replenishment claim, the size of the first production batch or the names of customers. ¹²

Tarantas News cautions that the claimed charging figure does not mean the battery continuously accepts the corresponding power: real charging depends on temperature, state of charge, station capability and electronics settings, and Svolt has not stated on which vehicle or against which driving cycle the 500 km in 12 minutes result was obtained. ³

On durability and safety, CarNewsChina reports a theoretical lifetime above 1 million km based on 3,000 charging cycles, and six layers of protection reportedly offering impact resistance three times the level of the Chinese governmental standard. Yang Hongxin said, according to CnEVPost, that a separator transfer-printing technology at cell level improves intrinsic battery safety while supporting fast charging and a long service life, and that high-speed stacking helps achieve the cycle-life figure. Tarantas News notes the million-km figure remains a theoretical calculation rather than a guarantee for a specific electric vehicle. ¹²³

For a 100 kWh pack, a 6C charging rate corresponds to a calculated peak of roughly 600 kW, Tarantas News reports, but that calculation does not represent continuous charging power. ³

A missed September target and a longer semi-solid roadmap

Svolt first revealed plans to mass-produce its semi-solid batteries in May 2026, initially aiming to roll out the first batch in September, CarNewsChina reports. The 26 October announcement confirms the first packs have now been made, but the volume of the first batch and the timing of deliveries to vehicle manufacturers have not been disclosed. ¹³

Cost was part of the May plan: Svolt said at the time that it planned to begin large-scale production of the 100 kWh semi-solid batteries in September, with costs expected to be on par with conventional liquid-electrolyte lithium-ion batteries, according to CnEVPost. ²

The company has also flagged what comes next. Tarantas News reports Svolt is separately developing a larger semi-solid battery of more than 120 kWh with even faster charging, slated for series production in the third quarter of 2027, and that the specifications of the two projects should not be conflated. ³

Strategically, Svolt sees semi-solid batteries as a competitive long-term option for battery electric vehicles, particularly those using ternary cells, rather than merely a transitional step toward all-solid-state batteries. Yang Hongxin said, according to CnEVPost, that it 'will become a mainstream technology over the long term', and the company will maintain a strategy of advancing semi-solid batteries first, followed by all-solid-state. Svolt has previously said all-solid-state batteries remain a long way from mass production. ¹²⁵

CarNewsChina reports Svolt aims to achieve a full-scale transition to hybrid solid-liquid technology for its ternary cells by the end of 2027 and plans to launch its third-generation hybrid solid-liquid technology in 2028. ¹

Svolt's market position and GWM ties

Svolt was formed by GWM in 2012 as a battery subsidiary and became independent in 2018, CarNewsChina reports, though it remains closely connected to GWM as a core supplier and strategic partner. CnEVPost notes the company was formerly GWM's power battery division and became independent in February 2018, with a business spanning battery materials, cells, packs and energy storage technology. ¹²

On scale, CnEVPost reports Svolt's global EV battery installations reached 22.0 GWh in the first eight months of 2026, up 39.3 per cent year on year, ranking it ninth globally with a 2.6 per cent share according to SNE Research. In China, Svolt ranked tenth in power battery installations in September with a 1.97 per cent share, and fourth in the ternary battery segment with a 6.31 per cent share, according to the China Automotive Battery Innovation Alliance (CABIA). ²

CarNewsChina, citing China EV DataTracker, reports Svolt's battery installations in China from January to September 2026 reached 11.27 GWh, comprising 4.23 GWh of LFP and 6.99 GWh of ternary NMC, giving the company a 2 per cent share of the Chinese market. ¹

A crowded next-generation battery field

Svolt's milestone arrives as other Chinese manufacturers pursue in-house cell programmes with different trade-offs. CnEVPost, reporting on Monday, notes Nio is pressing ahead with in-house large cylindrical cells under a model combining internal research and development with contract manufacturing by Eve Energy and Gotion High-tech, with a very small batch of cells expected by year-end even as mass production remains difficult in the near term, according to battery industry media outlet Jipian Lab. ⁴

The comparison is instructive but not like-for-like: Nio's 46105 cylindrical design, announced at Nio Day in 2023 with a stated cell energy density of 292 Wh/kg and 5C fast-charging support, has since changed and is no longer limited to that format, and Nio's ET9 flagship launched in December 2024 with a 100 kWh CATL prismatic pack instead of the originally planned 120 kWh in-house pack. Both companies therefore make future-generation claims whose real-world verification awaits confirmed vehicle applications. ⁴

For Svolt, the immediate test its technology faces is not another laboratory figure but the announcement of the first series-production model and a demonstrated vehicle-level charging result, as Tarantas News observes. ³
