Chinese battery manufacturer Svolt has introduced its Dragon Armor 3.0 pack, featuring a novel design that separates electrical terminals from pressure relief channels to control the direction of flames in the event of thermal runaway. By situating the positive terminal on one side and the pressure relief vent on the opposite side, the system channels any discharged flames downward and away from the vehicle’s passenger compartment.
Svolt reports that Dragon Armor 3.0 is the first square-cell format to combine Cell-to-Chassis/Cell-to-Body (CTC/CTB) integration with distinct thermal management paths. This layout boosts overall energy density by 7 to 10 percent within the same package footprint and increases individual cell height by 5 millimeters. The battery’s upper structure is engineered to bear mechanical loads, while the lower section provides a dedicated venting pathway and shared collision protection.
The company has also integrated liquid-solid state technology into the cell design. As a result, the self-heating temperature climbs by 8°C, extending the battery’s safety buffer time by 10 percent. Additionally, the onset temperature for thermal runaway rises by 5°C, and the likelihood of such an event is reduced by 25 percent.
Svolt plans to commence mass production of Dragon Armor 3.0 with two configurations: an 86 kWh pack for plug-in hybrid electric vehicles (PHEVs) and a 115 kWh pack for battery electric vehicles (BEVs). The 86 kWh version delivers more than a 10 percent improvement in cycle life and supports a pure electric range exceeding 400 kilometers.
First unveiled in December 2022, the Dragon Armor family initially delivered up to 800 km of range in LFP cell applications and supported 4C fast-charging in NCM formats. With the release of version 3.0, Svolt aims to advance both vehicle integration and on-board safety standards, addressing key industry priorities around energy density, thermal resilience, and crashworthiness.
