2025-07-29 | Calvin

On July 22nd, the second-generation Honeycomb Energy Dragon Scale Armor battery officially rolled off the production line at the Huzhou base. As an upgraded version of the original Dragon Scale Armor battery launched in 2022, this second-generation product represents the world's highest-capacity mass-produced 800V ternary range-extender battery, boasting an impressive 65kWh capacity while supporting 5C ultra-fast charging. This breakthrough significantly expands the range of applications for range-extender vehicles and delivers faster energy replenishment.

The Dragon Scale Armor II battery establishes its core competitiveness through ultra-high capacity, extreme safety, and ultra-fast charging. For safety innovation, it adopts an advanced integrated thermal-electric separation technology with higher stability. The breakthrough design positions the explosion-proof valve at the bottom of the cell, completely separating it from the electrodes on both sides to ensure absolute isolation between thermal runaway ejecta and electrical components.

The battery further establishes a triple-layer safety protection system featuring an intelligent fuse (response time <2ms) combined with ultra-high strength steel bottom guard plates and a T-shaped double-layer protective structure (impact resistance up to 1000J). Testing demonstrates that the Dragon Scale Armor II battery maintains "zero thermal propagation" even in 55°C high-temperature environments, exceeding industry safety standards by over six times.

Regarding capacity leadership, this battery currently stands as the world's highest-capacity mass-produced 800V 5C ternary range-extender lithium battery at 65kWh - approaching the capacity levels of pure EV batteries. Architecturally, it utilizes short-blade cells and CTP technology, sharing space between exhaust gaps and bottom protection layers to free up 5-8mm in the Z-axis direction, improving volumetric efficiency by 4%.

Furthermore, the Z-axis space optimization enables the Dragon Scale Armor II battery pack to adapt flexibly across MPV, SUV, and sedan platforms, significantly reducing both development and production costs.

For ultra-fast charging performance, the 5C technology achieves 20%-80% charge in just 12 minutes while supporting over 1,600 fast-charge cycles. When combined with BDU cooling technology, it reduces temperature by 40%.

The successful launch of the Dragon Scale Armor II battery marks a crucial milestone in Honeycomb Energy's development history and serves as a testament to China's rapid advancement in lithium battery technology. With all core indicators leading the industry, it will deliver users a new mobility experience characterized by enhanced safety, faster charging, and greater environmental sustainability.
