Mainland China-based battery manufacturer Gotion High-Tech unveiled innovative battery technologies on the sidelines of its 13th Technology Conference on May 17. The new innovations it unveiled included the 5C ultra-fast charging G-Current battery, high-nickel NCM (nickel, cobalt, manganese) cylindrical Stellary battery as well as all-solid-state battery technology at its annual event.

Gotion said that its innovative 5C ultra-fast charging G-Current battery can charge up to 80% state-of-charge (SOC) in just 9.8 minutes and up to 90% SOC in 15 minutes. “This solution can be applied to the entire range of battery applications, battery electric vehicles (BEVs) and hybrid electric vehicles,” the company said, adding that the fast-charging feature can be offered in batteries with multiple chemistries such as lithium iron phosphate (LFP), lithium manganese iron phosphate (LMFP) and NCM chemistry systems.

At the event, Cao Yong, vice president of the engineering research and development (R&D) Institute of Gotion High-tech said that the fast-charging G-Current batteries are ready for mass production.

Gotion also showcased its Stellary attery, which uses the battery maker’s self-developed second-generation silicon-carbon material and fast-charging electrolyte, enabling ultra-fast charging from 10% to 70% SOC in just 9 minutes.

According to Gotion, the battery packs equipped with these innovative cells can achieve 350 km of driving range by charging for just 5 minutes and 600 km of driving range by charging for 10 minutes.

“The unique structural design of the ‘Stellary Battery Pack’ can dissipate 70% of the heat outside the pack within only 3 seconds, ensuring maximum-speed cooling under extreme conditions and achieving the non-thermal propagation of the pack,” the company said, adding that the Stellary battery is also equipped with wireless BMS technology and multi-faceted effective cooling technology, which improves the safety and reliability of the battery.

Gotion also unveiled its Gemstone battery, which incorporates groundbreaking all-solid-state technology, boasting an energy density of 350 Wh/kg. According to the company, the energy density of its Gemstone battery is over 40% higher than the mainstream NCM batteries that are currently available in the market. Interestingly, Gotion’s all-solid-state battery has successfully passed the 200-degree hot box test in one go, a temperature significantly higher than the 130 degrees defined by national standards, marking a significant advancement in battery technology in terms of safety.
