Geely Unveils In-House Hybrid Battery Brand Jiyue Energy, Boosting EV Efficiency and Independence

Geely has officially joined the ranks of automakers that develop and manufacture their own batteries. This strategic move places the company alongside industry leaders like BYD, who have long integrated vertical capabilities in battery production. By creating an internal battery supply chain, Geely is aiming to further solidify its position in the electric and hybrid vehicle market.

At the 2024 Shanghai Auto Show, Geely announced the formation of its new battery division: Zhejiang Jiyue Mobility Energy Technology Co., Ltd., also known as Jiyue Energy. On May 29, during its Global Ecology Day event, Jiyue Energy revealed a new English brand identity and introduced its flagship product—the “Gold Brick Cell” battery series.

This new battery technology is specifically designed for use across Geely's hybrid vehicle lineup. One of the standout features is its dramatically improved charging efficiency. Traditional battery systems tend to slow down significantly when charging in the 80% to 100% state-of-charge (SOC) range. The Gold Brick Cell optimizes this range by reducing the charging time by 11.5 minutes, boosting efficiency by up to 75%. For everyday users, this means less waiting and more convenient top-ups.

Another common issue with standard hybrid batteries is power degradation when the SOC drops below 20%. In these situations, vehicle performance can suffer, particularly in acceleration and responsiveness. Geely’s new battery eliminates this concern completely, ensuring reliable power delivery even at low charge levels.

The Gold Brick Cell’s performance gains are made possible by several proprietary technologies. These include advanced active material encapsulation, which helps maintain consistent electrochemical activity, and a self-healing SEI (solid electrolyte interphase) film that extends overall battery life and enhances durability. These innovations contribute to both performance stability and long-term reliability.

Until now, Geely's hybrid models have relied on batteries from external suppliers, including CATL, SVOLT, VREMT, and CALB. By developing and producing batteries in-house, Geely can now exercise greater control over product quality and supply chain management. This shift is also expected to bring down overall vehicle manufacturing costs, providing the company with a competitive advantage in pricing and scalability.

Looking ahead, if Jiyue Energy can ramp up production and maintain cost competitiveness, it opens the door for Geely to become a battery supplier to other automotive brands. This would not only enhance its revenue streams but also establish Geely as a major player in the global EV battery market.

Through this strategic expansion into battery technology, Geely is redefining its role in the electric mobility ecosystem, combining manufacturing, innovation, and energy technology under one roof.
