中文Recently, ultra-high energy-density lithium-rich manganese solid-liquid batteries have been successfully installed in vehicles by China FAW Group’s subsidiary, China Auto New Energy Battery Technology Co., Ltd., marking an industry-first achievement!
The ultra-high energy-density lithium-rich manganese solid-liquid battery product, jointly developed by China Auto New Energy and the research team led by Academician Chen Jun of Nankai University, represents a significant breakthrough in China’s high-energy-density power battery sector and signifies the official entry of lithium-rich manganese solid-liquid battery technology into the commercialization stage.
The battery cell boasts an energy density of 5003 Wh/kg, more than double that of mainstream lithium iron phosphate batteries. The battery pack capacity has increased by 67% year-on-year, reaching a total capacity of 142 kWh. When installed in vehicles, this enables a driving range exceeding 1,000 km.
The battery employs a self-developed ultra-wetting in-situ cured composite electrolyte technology, combining the high safety of solid-state batteries with the high ionic conductivity of liquid batteries. This effectively addresses the challenge of high interfacial impedance commonly found in traditional solid-state batteries.
With ultra-high specific capacity and energy density, its theoretical specific capacity can reach 400–450 mAh/g, far surpassing that of traditional ternary materials. The innovative “Thermal-Electrical-Mechanical-Gas-Fire” five-dimensional protection technology ensures no thermal propagation in the battery system, significantly enhancing safety.
It is reported that lithium-rich manganese solid-liquid batteries fall under the category of semi-solid-state batteries, serving as a transitional technology from liquid lithium batteries to all-solid-state lithium batteries. By maintaining the high ionic conductivity of liquid electrolytes while incorporating solid electrolytes, they enhance interfacial stability and safety.
Plans are in place to commence pilot operations in 2026 to validate the battery’s reliability and durability in real-world usage environments. Continuous optimization of battery materials and structures will be pursued, with the goal of achieving a system energy density exceeding 340 Wh/kg, a battery pack capacity surpassing 200 kWh, and a driving range of 1,600 km.
