In the first half of 2025, the company’s power battery shipments reached 16.08 GWh, a year-on-year increase of 93.04%.
On October 23, at the 2025 New Energy Battery Industry Development Conference, Sunwoda launched its new-generation polymer-based all-solid-state battery named “Xin·Bixiao”.
The battery boasts an energy density of 400 Wh/kg and achieves a cycle life of 1,200 cycles under an ultra-low external pressure of <1 MPa. Sunwoda expects to complete the construction of a 0.2 GWh pilot production line for polymer solid-state battery cells by the end of this year.
A relevant executive at Sunwoda stated that the company has also successfully developed and tested a laboratory prototype of a lithium-metal super battery with an energy density of 520 Wh/kg.
Based on technical feasibility and industrialization progress, Sunwoda’s solid-state battery technology roadmap has gradually become clear:
The first generation of semi-solid-state batteries has completed R&D, with energy density exceeding 300 Wh/kg; the second generation of semi-solid-state batteries has entered the pilot sample stage, with further improved performance; the third generation of all-solid-state batteries has completed the verification of sample solutions at the 400 Wh/kg level, and the commercialization process is accelerating.
The polymer solid-state battery cell represents a significant breakthrough for Sunwoda in next-generation battery technology.
The 400 Wh/kg energy density is significantly higher than that of current mainstream liquid lithium-ion batteries, meaning it can store more energy under the same weight. This will notably enhance the driving range of electric vehicles or provide a safer, higher energy-density power solution for emerging fields such as low-altitude aircraft.
In the power battery sector, Sunwoda has demonstrated remarkable performance in recent years. In the first half of 2025, the company’s power battery shipments reached 16.08 GWh, a year-on-year increase of 93.04%.
It is worth mentioning that in May of this year, at the CIBF2025 exhibition, Sunwoda launched the “Xin·Yunxiao 2.0” aviation power battery. With an energy density exceeding 360 Wh/kg, it utilizes “soft solid-state” battery technology as its core, combining high specific energy, high power, high safety, and a wide operating temperature range.
The company also introduced the Flash-Charge Battery 4.0 series. Among them, the Xin Xingchi 2.0 Kilo-Amp Extreme Fast Charging version increases the charging current to 1,400 A. Coupled with a vehicle-side 1,000 V high-voltage system platform, it can achieve a maximum flash-charging power of 1.4 megawatts, capable of adding over 150 kilometers of range in one minute.
The energy storage business has become another growth engine for Sunwoda, following consumer batteries and power batteries. In the first half of 2025, the company’s energy storage business revenue reached 10.2 billion yuan, a year-on-year surge of 133%, with energy storage battery shipments reaching 8.91 GWh.
In overseas markets, Sunwoda’s energy storage cell shipments accounted for 62% of the total. The company has signed long-term supply agreements with international energy giants like bp and TotalEnergies. On October 16, Sunwoda announced its intention to apply for a 67 million yuan new policy-based financial tool loan from the Shenzhen Branch of China Development Bank to fund the construction of three energy storage power station projects by its subsidiaries.
