South Korea’s battery manufacturers are losing ground to their Chinese competitors, according to recent stock market data released on Wednesday. While China’s Contemporary Amperex Technology Co. (CATL), the world’s largest battery manufacturer, continues to build momentum following record quarterly earnings, Korean companies are facing investor skepticism about their future growth.
Shares of LG Energy Solution dropped 4.3 percent to close at 300,500 won ($208.08). Samsung SDI also saw significant losses, falling 4.71 percent to finish at 364,000 won. Both stocks opened higher initially, but sentiment deteriorated rapidly during the session. This decline followed a steep drop in chip stocks, specifically Samsung Electronics Co. and SK hynix Inc., which dragged down broader market confidence.
In sharp contrast, CATL’s stock rose 1.53 percent to close at 396.84 yuan ($58.65) on the Shenzhen Stock Exchange. The divergence highlights a growing gap between the two regions as the battery market evolves. Investors are rewarding the Chinese firm for its financial results and strategic positioning, while Korean peers struggle to maintain their footing.
Record Earnings Drive Chinese Growth
CATL’s recent stock performance is directly tied to its second-quarter financial results, which exceeded market expectations. The company reported revenue of 147.79 billion yuan, representing a 56.9 percent increase from the previous year. Net profit rose 36.5 percent to 22.5 billion yuan. Both figures reached record quarterly highs for the manufacturer.

The most notable aspect of these earnings is the shift in the company’s primary growth engine. Industry observers point out that CATL is no longer relying solely on electric vehicle (EV) batteries for expansion. Instead, the company’s energy storage system (ESS) business has become the dominant driver of its success.
This pivot comes at a time when demand for energy storage is surging globally. The rapid expansion of artificial intelligence data centers has created a massive and unexpected demand for electricity. As tech companies scramble to power these energy-intensive operations, the need for large-scale battery storage solutions has naturally intensified.
If the surge in data center electricity demand proves sustainable, the current divergence in stock performance might persist, as Chinese firms appear better positioned to scale production rapidly enough to meet that specific need. Korean manufacturers are attempting to pivot toward the same sector, but they are entering a market where their rivals have already secured a formidable lead in both output and cost efficiency.
Expansion Plans and Strategic Shifts
Investors are also closely watching CATL’s aggressive global expansion strategy. The company raised about $5 billion through a listing in Hong Kong earlier this year and plans to use the proceeds primarily to expand overseas production bases. This includes a significant plant in Hungary, which will serve the European market.

Additionally, the company announced plans to repurchase up to 40 billion yuan worth of its own shares, a move that often signals confidence in future valuation. These financial maneuvers provide CATL with the capital necessary to push into new territories while rewarding shareholders.
Korean battery makers, by comparison, are showing only a tentative recovery in their performance. Both LG Energy Solution and Samsung SDI are positioning large-scale ESS projects as a key growth driver to overcome the current slowdown in the EV market. However, the path forward is fraught with difficulty.
The primary challenge remains the aggressive price competition initiated by Chinese rivals. While Korean firms possess advanced technology, they continue to face the threat of surviving a market where competitors are willing to cut prices deeply to gain market share. The recent stock performance suggests that, for now, investors are betting on the Chinese strategy.
