Advancements in Battery Technology
Chinese battery manufacturer Gotion High-Tech has reached a significant milestone with the completion of a 0.2 GWh pilot production line for its GEMSTONE all-solid-state battery, which boasts a 90% yield rate. This next-generation battery marks a notable upgrade in technology, featuring a 60% improvement in sulfide electrolyte ion conductivity, 150% enhancement in cell capacity, and a reduction of 90% in pre-tension force during stacking.
Safety is a critical aspect of Gotion’s development process, with their testing protocols including diverse evaluations such as nail penetration, crush tests, and assessments of thermal stability. The company has commenced road testing, aiming to validate performance in real-world conditions.
In addition to the GEMSTONE battery, Gotion has unveiled six new energy products, which include the G-Yuan quasi-solid-state battery. The G-Yuan battery has an impressive energy density of 300 Wh/kg, enabling electric vehicles (EVs) to achieve ranges exceeding 1,000 km. Its advanced adaptive solid-solid interface technology is designed to ensure stable ion transport, confirmed through a rigorous 3 mm steel nail penetration safety test. Gotion is also in the process of constructing a 12 GWh production line, with prototype vehicles already surpassing 10,000 km in road testing.
The G-series is particularly noteworthy, featuring a 116 kWh high-capacity battery designed for heavy-duty trucks. It delivers 175 Wh/kg of specific energy, facilitating megawatt-level ultra-fast charging capabilities and operating effectively within extreme temperatures ranging from -40° C to 65° C. Gotion claims zero capacity decay over the first 3,000 cycles, alongside no energy loss over 1.2 million kilometers of driving and an ultra-long cycle life of 12 years or 10,000 cycles.
Moreover, Gotion’s Grid Q energy storage system boasts a capacity of 20 MWh per unit, with a design life of 25 years. Its modular structure is optimized for space efficiency, and its Air+Liquid cooling system ensures effective thermal management.
Lastly, the Astroinno Gen-2 lithium manganese iron phosphate (LMFP) battery can achieve ultra-fast charging in just 10 minutes, offering a specific energy capacity of 240 Wh/kg while retaining 93% efficacy in cold conditions at -20° C. The battery successfully passed thermal runaway tests at the PACK level, showcasing Gotion’s commitment to safety alongside performance.
As Gotion High-Tech continues to pave the way in battery innovation, these advancements indicate a promising future for electric vehicles and energy storage solutions.
