On a recent evening in April, Contemporary Amperex Technology Ltd (CATL), the world’s largest electric vehicle (EV) battery manufacturer, showcased its latest advancements in battery technology at an event held at Beijing’s National Convention Centre. The company introduced its third-generation Shenzing battery series, which promises significantly faster charging times, improved safety, and enhanced efficiency.

CATL’s new battery technology can charge from 10 to 98 percent in under six and a half minutes, a notable improvement compared to BYD’s Blade battery, which requires nine minutes to reach 97 percent charge. Gao Huan, CATL’s chief technology officer for automotive batteries, emphasized the company’s focus on thermal management, explaining that the Shenzing series uses independent sealed exhaust channels to separate heat and electricity, preventing heat from spreading and accelerating battery degradation. Gao also highlighted the company’s rigorous quality control, which includes 7,000 quality checkpoints in the manufacturing process.

The battery pack, accounting for approximately one-quarter of an EV’s overall cost, remains a critical component for the automotive industry’s transition to electrification. Technological improvements are essential to address concerns over production costs, driving range, and vehicle safety.

CATL, headquartered in Ningde, Fujian province, held a 40.2 percent share of the global EV battery market in the first five months of 2026, according to South Korea-based SNE Research. During this period, global EV battery usage increased 16.3 percent year-on-year to 469.2 gigawatt-hours (GWh). For context, one GWh can power roughly 20,000 EVs with a 500-kilometer range.

Morgan Stanley noted that the reduced charging time offered by the Shenzing batteries could alleviate common consumer anxieties related to range and charging convenience. However, debates persist regarding the safety and durability of ultra-fast charging technologies.

In China, the world’s largest automotive market, new energy vehicles—including pure electric and plug-in hybrids—represented 57.4 percent of new vehicle deliveries in the first half of 2026, according to the China Passenger Car Association. Battery costs have declined sharply over the past decade, dropping from about $1,474 per kilowatt-hour (kWh) in 2010 to nearly $108 per kWh in 2025, according to BloombergNEF.

Chinese firms dominate the global EV battery market, with seven companies—including CATL, BYD, and Gotion High-Tech—ranking among the top ten suppliers worldwide. Between January and May 2026, these Chinese companies held a 72.6 percent share of the global market, per SNE Research.

Industry experts point to the potential disruption posed by emerging technologies such as solid-state batteries, which offer higher energy density, longer ranges, and enhanced safety by eliminating flammable liquid electrolytes. Chinese authorities have prioritized investment in solid-state battery research and production. Several domestic companies have already made progress: WeLion’s semi-solid-state batteries power some premium EVs from Nio, while Cherry Automobile unveiled an all-solid-state battery capable of driving over 1,500 kilometers on a single charge.

Leading lithium producers like Ganfeng Lithium are also advancing battery longevity, aiming for energy storage devices lasting upwards of 18,000 charge cycles—comparable to the lifespan of solar panels. Gotion High-Tech has introduced batteries capable of being recharged over 15,000 times, with capacities exceeding 580 ampere-hours (Ah) and plans to increase further.

The rapid evolution of China’s EV battery industry is largely attributed to intense domestic competition, according to Ganfeng Lithium’s president, Wang Xiaoshen. Analysts suggest that although international competitors may achieve breakthroughs in specific technologies, China’s integrated manufacturing and supply chain systems grant it a sustained advantage in mass-producing batteries.

Furthermore, battery manufacturers are increasingly collaborating with automakers to embed battery technologies deeper into vehicle architectures. This “cell-to-chassis” approach integrates battery cells directly into the car’s structural components, aiming to reduce weight, save space, and boost energy density. CATL’s Panshi intelligent chassis, launched in late 2024, combines battery, motor, power electronics, suspension, braking, and steering elements, promising enhanced crash safety, extended range, and support for intelligent driving functionalities.

Financially, CATL reported a net profit of 72.2 billion yuan ($10.2 billion) for 2025, up 42 percent from the previous year, nearly matching the combined profits of China’s largest automakers BYD, Chery, Geely Auto, and SAIC. In the first half of 2026, CATL’s net profit rose 42 percent year-on-year to a record 43.28 billion yuan.

At the April event, CATL founder and chairman Robin Zeng Yuqun emphasized the importance of quality and innovation in expanding China’s global presence in the EV sector. “We must bank on high-quality innovation and proven capabilities,” Zeng said. “We hope that what goes global is not just the Chinese products, but also the credibility of Chinese brands.”
