While new energy vehicles are still anxious about their range and electronic device safety issues continue to affect people's hearts, a quiet energy revolution is unfolding in China. In 2025, China's first high-capacity all solid state battery production line will be officially put into operation. This news, released by authoritative media, instantly ignited the enthusiasm of the capital market and the technology industry. This is not only the landing of a factory, but also means that China has taken the lead in the global race for the next generation of power batteries, breaking through the laboratory and heading towards the industrialization track. Behind it is a company called Dangsheng Technology, which is leading the way with a "black technology" with an energy density of up to 500Wh/kg.

The dilemma of liquid batteries and the dawn of solid-state batteries

For a long time, the development of mainstream liquid lithium batteries seems to have hit a "ceiling". The energy density hovers between 250-350Wh/kg, making it difficult for electric vehicles to exceed the 800 kilometer mark in range; Flammable liquid electrolytes pose safety hazards, with over 2000 self ignition accidents of new energy vehicles in China in 2024 alone. In addition, in low-temperature environments, the performance of batteries will rapidly deteriorate, which restricts their application in a wider range of regions and scenarios.

At the same time, emerging technology industries have put forward higher requirements for energy. Whether it is electric flying vehicles (eVTOLs) that require long-term flight or humanoid robots that pursue lightweight and long-lasting performance, traditional liquid batteries are no longer sufficient. The emergence of all solid state batteries is seen as a "dimensionality reduction blow". It uses non combustible solid electrolytes, with a thermal runaway temperature exceeding 300 ℃, and extremely high safety; The energy density can easily exceed 400Wh/kg, and is even expected to reach 500Wh/kg; In an extremely cold environment of minus 30 degrees Celsius, the performance degradation is less than 5%. As industry experts have pointed out, the development of solid-state batteries is no longer a "multiple-choice question" for China's lithium battery industry, but a "survival question".

The way to break through the situation of Dangsheng Technology: conquering the three major technological barriers

However, to turn solid-state batteries from blueprints into reality, it is necessary to overcome three major global challenges: solid solid interface impedance, electrolyte stability, and material compatibility. After nearly a decade of dedicated research and development, Dangsheng Technology has presented a "three in one" solution.

Firstly, in terms of core electrolyte materials, Dangsheng Technology has pioneered the world's first "chloride iodine composite" sulfide solid electrolyte. This technology cleverly solves the problem of poor contact between electrodes and electrolytes, without the need to apply huge external pressure like early technologies, and can achieve efficient ion conduction, clearing obstacles for large-scale production.

Secondly, in terms of determining the upper limit of battery energy, Dangsheng Technology has taken ultra-high nickel multi-element materials and lithium rich manganese based materials to new heights. The latter has pushed the energy density of all solid state batteries to the industry peak of 500Wh/kg. This means that in the future, the range of electric vehicles is expected to exceed 1200 kilometers and achieve a top speed recharge of "charging for 10 minutes and driving 800 kilometers".

Locking in the future: Capacity layout and trillion dollar market launch

Technological breakthroughs require the implementation of production capacity. In October 2024, Dangsheng Technology announced the investment and construction of a solid electrolyte industrialization project with an annual output of 3000 tons in Jintan, Jiangsu, aiming at the world's leading solid electrolyte supply base. At the same time, its overseas bases are also rapidly advancing to respond to the needs of international giants.

This series of layouts precisely follows the rhythm of market explosion. Industry forecasts indicate that there will be a peak in the production capacity of semi-solid state batteries from 2025 to 2026, and all solid state batteries will enter the stage of large-scale production after 2030. By 2035, the global shipment of solid-state batteries is expected to exceed 900GWh, creating a trillion dollar market. The early positioning of Dangsheng Technology has given it a first mover advantage in the upcoming wave of GWh level production line construction.

At present, semi-solid state batteries based on Dangsheng Technology materials have been applied in multiple high-end new energy vehicles in China, helping the vehicle range exceed 1000 kilometers and achieving sales of over 100000 units in 2024. In the field of low altitude economy, its batteries have increased the endurance of electric aircraft by 60% to 90%; In the field of drones and humanoid robots, the device's endurance has been doubled, meeting the needs of all day operations.

From technological catch-up to global leadership, China's breakthrough in solid-state battery technology is quietly rewriting the competitive landscape of the global new energy industry. With the landing of China's first all solid state battery production line, an energy storage revolution led by the East has officially begun.
