In 2025, the penetration rate of new energy vehicles will break through 60%, driving the rapid increase in battery installation.
According to data, in the first quarter of 2025, the global sales of new energy vehicles totaled 3.938 million, a year-on-year increase of 29%, driving the installed capacity of power batteries to 206.9GWh, a year-on-year increase of 36%. Among them, the installed capacity of lithium iron phosphate batteries reached 106.6GWh, accounting for 51.5% of the global market share.
From a technical perspective, battery technology continues to evolve. Now, multi-type technical routes such as large cylinders, ultra-fast charging, and solid-state batteries compete on the same stage, and downstream application scenarios have also been greatly expanded. Commercial electric vehicles, humanoid robots, aircraft and other emerging fields urgently require higher energy density, safety, and cycle life.
Aiming at the next generation of battery technology and the trend changes in industrial applications, Honeycomb Energy recently demonstrated the second-generation dragon scale armor battery and the latest stacking technology. At the same time, Yang Hongxin, chairman of Honeycomb Energy, and Zhang Fangnan, vice president of Honeycomb Energy, "revealed" related products and technologies from multiple dimensions such as products, manufacturing, and quality.
Yang Hongxin believes that supercharging and solid-state are the evolutionary directions of future battery technology, and stacking is the best solution to achieve mass production of supercharging and solid-state batteries.
Taking supercharging technology as an example, the notable feature of supercharging cells is that the transmission rate of lithium ions is greatly improved compared to conventional cells, which requires supercharging cells to have pole pieces during the manufacturing process.
The current collector has low internal resistance, is evenly stressed during charging and discharging, has a small degree of deformation, and has a higher degree of interface adhesion. In this case, stacking production performs better than winding.
In terms of solid-state batteries, since solid electrolytes are brittle and easy to break, whether they are oxides, sulfides or halides, stacking has become the only technical route for mass production of all-solid-state batteries.
Second-generation dragon scale battery unveiled
At the CIBF2025 held recently, Honeycomb Energy brought a heavyweight second-generation dragon scale battery, and will start large-scale mass production in mid-June.
At a time when battery technology iteration is accelerating, as its trump product, Honeycomb Energy's second-generation dragon scale battery has many highlights.
According to Yang Hongxin, the second-generation dragon scale battery has reached a new benchmark in comprehensive dimensions such as safety, energy density, and fast charging performance. Honeycomb Energy's second-generation dragon scale battery is the world's largest 800V 65-degree electric hybrid battery with a range of more than 400KM and 5C fast charging.
The battery pack adopts CTP design, the volume utilization rate is increased by 2-4%, and the system energy density reaches 185kWh/kg. As a plug-in hybrid fast charging battery, its fast charging cycle exceeds 1,600 cycles. The battery pack also uses BDU cooling technology, the BDU temperature can be reduced by 40%, while improving the current carrying capacity, it can be expanded to 6C super charging.
Yang Hongxin further mentioned that the current fast-charging battery is developing rapidly, but there are still shortcomings in actual experience, mainly reflected in the fact that the industry can already achieve fast charging at 20-80% SOC, but in 80-100% SOC charging, most of the battery cells have insufficient fast charging capabilities.
In order to solve this shortcoming, Honeycomb Energy improves the charging capacity boundary of the battery cell through the stacking process, uses digital and intelligent dual temperature control monitoring systems, and dual-item 5-dimensional fast charging strategies to achieve terminal energy replenishment and true fast charging. It is understood that compared with conventional fast-charging cells, the 80-100% SOC fast charging performance of Honeycomb Energy under the stacking process is improved by more than 30%.
The outstanding feature of Honeycomb Energy's second-generation dragon scale armor battery is its safety. Zhang Fangnan, vice president of Honeycomb Energy, said that Honeycomb Energy's second-generation dragon scale armor battery uses highly integrated and highly stable thermoelectric separation technology, which eliminates the risk of short circuits by absolutely separating the thermal runaway ejecta from the electrical components in the package.
At the same time, the second-generation Dragon Scale Armor battery pack uses an intelligent fuse with a cut-off time of less than 2ms and a response time increased by 5 times. An ultra-high-strength steel bottom guard plate + T-shaped double-layer profile protection structure is used at the bottom of the battery cell. There is no safety risk after a 1000J impact, and the safety standard is more than 6 times the industry standard, meeting the new national standard ahead of schedule.
Improvement of thermal composite flying stacking process
As the builder of the short knife strategy, Honeycomb Energy's technical strength in the short knife battery cell is unquestionable.
Its latest generation of short knife battery cells can achieve a 6C charging rate, an energy density of 195kWh/kg, and a cycle life of more than 5,000 times. The outstanding performance of Honeycomb Energy's short knife battery cells also stems from its thermal composite flying stacking process.
Compared with traditional stacking technology, Honeycomb Energy's thermal composite flying stacking technology maximizes stacking efficiency through intelligent production and all-round innovation of technology. Under Honeycomb Energy's thermal composite flying stacking process, the flying stacking technology adopts a multi-electrode parallel structure, which further reduces the internal resistance of the wound battery cell. Under the same working conditions, it can help the short knife battery cell to reduce the temperature rise of fast charging, effectively improving the fast charging performance. The unique thermal composite technology of the flying stacking technology can also increase the electrolyte storage space and increase the long cycle life of the fast charging cell.
In the past year, Honeycomb Energy has proposed the golden technology combination of "short knife + flying stacking". Now, with the exploration of technology, "short knife + flying stacking" is expected to lead the industrialization of solid-state batteries.
Zhang Fangnan mentioned that Honeycomb Energy's third-generation hot composite flying stacking technology simplifies the four processes of all-solid-state battery preparation into one through the deep integration of pole piece flying cutting, hot composite and high-speed stacking processes, and improves production efficiency by 100%, with a yield rate of over 99.5%. The single-machine efficiency of this technology reaches 0.125s/pcs, and the space occupancy is reduced by 45% and the cost is reduced by 53%.
Its special diaphragm technology increases the bonding force of pole pieces by 5 times, reduces the Hi-pot defective rate by 30%, and realizes a 250-item closed loop of detection through the A1 full inspection system, reducing the risk of defective product outflow by 60%.
Hot composite flying stacking technology is not only a strong support for the mass production of Honeycomb Energy's all-solid-state batteries, but also promotes its market strategy from "technology leadership" to "large-scale delivery".
