New Breakthrough in Solid-State Batteries: Gotion Announces Cost Target
· AI · Cem Koyluoglu
Battery manufacturer Gotion highlights new progress in preparing solid‑state batteries for industrial production at the World Manufacturing Convention 2026 in Hefei and announces its latest targets.
TL;DR Gotion announced a 400 Wh kg⁻¹ energy‑density goal for solid‑state cells and a cost target of about one yuan per watt‑hour, while moving from a 0.2 GWh pilot line to a planned 2 GWh production line by 2026. The company also partnered with BASF to tackle material bottlenecks and is on track for full serial production by 2030.
Key Highlights • 400 Wh kg⁻¹ energy‑density target for solid‑state cells, up from 350 Wh kg⁻¹. • Cost goal of roughly one yuan per watt‑hour (~150 USD kWh⁻¹) for mass‑produced cells. • Transition from 0.2 GWh pilot line (2025) to 2 GWh annual production line finalized in March 2026. • Collaboration with BASF to develop high‑performance materials and address technical bottlenecks.
Gotion Highlights Solid‑State Battery Milestones at World Manufacturing Convention 2026
At the World Manufacturing Convention 2026 in Hefei, battery maker Gotion showcased the latest advances in preparing solid‑state batteries for industrial production and disclosed its most recent objectives.
Energy Density Target
According to CarNewsChina, Gotion has set a new energy‑density goal of 400 Wh kg⁻¹ for its solid‑state cells. The company had previously announced a 350 Wh kg⁻¹ target for sulfur‑based solid‑state cells. When the new benchmark will be reached in serial‑production‑ready cells remains unclear.
Cost Objective
Gotion also outlined a concrete cost target. The firm aims to enter a “single‑yuan period,” where its solid‑state batteries would cost roughly one yuan per watt‑hour, or about 150 USD per kilowatt‑hour. This figure is still noticeably higher than the current average price of Chinese LFP cells.
Current Development Stage
The present development phase builds on earlier steps. In 2025, Gotion launched a pilot production line with a 0.2 GWh annual capacity. The fully solid‑state cells produced there were integrated into vehicles and tested on the road, achieving an energy density of 350 Wh kg⁻¹.
Approaching Mass Production
The company announced in 2024 that it would begin small‑scale production in 2027 and target full serial production by 2030. The timeline has since advanced: as of March 2026, Gotion finalized the design for a 2 GWh annual solid‑state battery production line.
Material Expertise Expansion
Parallel to production, Gotion is broadening its material capabilities. In early 2026, the battery maker signed a collaboration agreement with BASF to develop high‑performance materials for solid‑state batteries. Both firms intend to overcome technical bottlenecks on the path to commercial use and jointly explore opportunities for a future market launch.
Safety Testing
Gotion highlighted the safety performance of its cells. In puncture and high‑temperature tests, the cells produced no smoke or flame. The Chinese group, one of the country’s largest battery manufacturers, operates 20 production facilities worldwide.
Market Position
China EV DataTracker data indicate that by August 2026 Gotion reached an installed battery capacity of 4.61 GWh, placing it fifth in the Chinese market.
Volkswagen’s Involvement
Volkswagen, Gotion’s largest shareholder, plans to strengthen its ties with the Chinese partner in Europe. A large joint‑venture agreement based on three co‑ownership structures is anticipated.
