HSBC: After Two Years Of Pain, China's Battery Sector Enters A New Upcycle

In a note that will be read closely from Shenzhen to Frankfurt, HSBC's China Autos research team has declared a definitive end to the two-year downturn in China's massive battery industry. The November 11, 2025 report, titled "The tide has turned," argues that a powerful cyclical recovery is now undeniably underway, driven by surging demand for both energy storage systems (ESS) and electric vehicles.

After a brutal period of overcapacity, price wars, and decimated profits for all but the top players, the bank sees "clear evidence of an upcycle." This is a significant call, suggesting that pricing power is returning and a new capacity expansion phase is beginning, creating a potentially lucrative window for investors who have weathered the storm.

A "Surging" Demand Shock

The recovery isn't tentative; it's explosive, particularly in the ESS and commercial vehicle segments. HSBC lays out the data, noting a dramatic reversal from the slump that began in 2023.

"After a tough two years, the data for 9M25 shows that the tide has turned for China’s battery industry. Demand is surging across the energy storage system (ESS) and EV segments. China’s ESS battery sales in 9M25 reached 211GWh (+66% y-o-y) domestically and 71GWh (+110% y-o-y) overseas, fuelled by domestic ESS policy reforms and subsidies, as well as export demand from Europe, the Middle East, and Australia."

The momentum in the electric vehicle space is equally compelling, especially in the often-overlooked commercial sector. Policy support, including generous trade-in subsidies that can reach up to RMB 140,000 (approx. US$19,400) per vehicle, has ignited adoption.

"In the EV space, domestic commercial vehicle battery installations increased 136% y-o-y to 92GWh, driven by rising EV adoption in commercial vehicles as a result of policy support (purchase tax exemption and trade-in subsidies) and cost parity with ICE vehicles."

HSBC points out that not only are government incentives at play, but electric heavy trucks have now reached total cost of ownership (TCO) parity—and are often cheaper—than their diesel and natural gas counterparts, a critical inflection point for mass adoption.

Supply Reacts: A New Expansion Wave

This demand shock is colliding with a supply side that has been deliberately constrained for two years. The report details how the bruising price war forced discipline, with most smaller manufacturers operating at utilization rates below 50%. This painful consolidation is now giving way to a new expansion cycle, led by the survivors.

According to HSBC, the dynamic is shifting rapidly:

"In 1H25, leading battery suppliers operated at near full capacity, and second and third-tier supplier utilisation rates increased to 50-70%. We believe the cyclical turning point is underway, evidenced by: 1) accelerating capacity expansion plans announced by the top five battery makers, led by CATL… and 2) price increases on selected quality products due to a supply shortage."

This marks a crucial change. After years of destroying capital, the industry is entering a phase where tight supply for high-quality products allows for both volume and price expansion, a classic recipe for improved profitability.

Pricing Power Returns from the Trough

For investors, the most critical signal is the return of pricing power. HSBC notes that the supply-demand rebalancing has allowed prices to finally lift off the floor since mid-2025. It's a broad-based recovery, seen not just in finished battery cells but across the entire supply chain.

The bank highlights that in the last three months alone, LFP and Ternary battery cell prices have risen 3-4%, lithium carbonate is up 14%, and key components like separators have seen prices jump 6-8%.

HSBC believes this is just the beginning. "We believe this upcycle will continue, with the EV/ESS battery segment expected to see both volume and price expansion next year," the report states. With new capacity taking time to come online, this price and volume expansion window could persist.

HSBC's Top Picks: Riding the Upcycle

With the recovery thesis established, HSBC identifies three key players positioned to benefit, all a "Buy":

• Contemporary Amperex Technology, or CATL, is the undisputed leader. HSBC likes it "on the growing conviction in volumes and pricing improvements." With its dominant market share and multiple growth engines across EV and ESS, both at home and abroad, the bank believes its outlook is strong enough to withstand any minor seasonal slowdowns.
• Yunnan Energy New Material, the separator segment leader, is a clear cyclical recovery play. After struggling with pricing during the downturn, the stock has already rallied, but HSBC argues "the upcycle momentum has not been fully priced in." Tight supply in the separator market is expected to drive prices higher.
• REPT BATTERO Energy, is a turnaround story. The bank expects the company's profitability to inflect in 2025, driven by strong ESS volume, expanding economies of scale, and the marginal pricing improvement lifting all boats.

While HSBC acknowledges risks, such as a sharper-than-expected contraction in global demand, its overriding message is one of conviction. The data from the first nine months of 2025 signals that the long winter for China's battery sector is over, and a new, more profitable season has begun.
