Battery Cycles Revisited: What the 2021 Supercycle Teaches Us About Investing in 2026-2027

The Headline Lesson: This Isn't a Repeat

Markets love a good comparison. When battery material prices started recovering in 2025, the narrative quickly formed: here comes another supercycle like 2021-22. But the fundamentals tell a different story. This recovery is selective, not systemic — and investors who treat it as a mirror of the past are setting themselves up for disappointment.

The 2021-22 boom was a perfect storm: near-zero interest rates, a rapid surge in China's EV adoption, aggressive capacity expansion, massive capital inflows, and a raw material price explosion that saw lithium carbonate climb over 1,300%. Today, we have none of those tailwinds. Interest rates sit around 3.75%. Demand is more diversified (more on that below). Capacity growth is disciplined. And while lithium has risen 130% from its trough, that's a far cry from 1,300%.

Why Stock Prices Peaked Before Prices Did

Here's an often-overlooked pattern from the previous cycle: stock prices peaked before the underlying commodity prices hit their highs. Yunnan Energy's share price peaked in September-October 2021 — the same time separator sales prices were just starting to rebound from their lows. The market was pricing in future price increases before those increases had even materialized.

This has a practical implication for today's investors: don't chase when expectations become crowded. In 2025, LFP cathode producers (like Hunan Yuren) and separators (like Yunnan Energy) delivered strong returns on price recovery trades. But the play is to buy during weak periods and sell into strength, not the reverse.

Demand Has Changed Dramatically

The demand composition in 2026 looks nothing like 2022:

ESS (energy storage systems) has emerged as the dominant growth driver, now accounting for over 40% of battery demand. This diversification makes the profit story more resilient but the investment narrative less clean. You can't just say "EV penetration is accelerating" and expect battery stocks to rally like before.

Policy: From Encouragement to Caution

The previous cycle had local governments actively subsidizing and pushing expansion. Today, the central government is tightening the reins: anti-cyclical reviews, fair competition enforcement, reduced direct subsidies, and strategic support channeled through industrial funds rather than blanket incentives.

Specific recent moves:

• NIO subsidies reduced in January 2026
• Purchase tax incentives halved
• Battery export tax refunds cut (April 2026: 4% → 3%; January 2027: 6%)
• Possible 2% battery consumption tax

These aren't death blows, but they remove tailwinds. And the national storage subsidy framework — while positive — targets 2027, creating a potential installation slowdown in 2028 that could weigh on battery shipments in 2027.

Where the Money Actually Flows

In the 2021-22 cycle, profits pooled at the upstream — lithium producers like Ganfeng hit a quarterly net profit peak of 6.1 billion yuan in Q4 2022. In the current cycle, most supply chain companies are still 20-80% below those peaks.

The exception: CATL. Contemporary Amperex Technology has delivered stable, substantial profit growth throughout both cycles, benefiting from scale, technology leadership, pricing power, and excellent cash flow. This is the only battery manufacturer I'd call a "core holding" — the industry's quality anchor for long-term exposure.

Other names like Putailai and CALB offer opportunities, but they're volume-growth stories, not ASP-beta plays. Treat them as cyclical trades, not compounding machines.

Valuation: A Lower Ceiling

The rate environment alone changes everything. In 2021, the Fed funds rate was 0.25%. Today it's 3.75%. That supports much higher P/E ratios for growth stocks. During the last cycle, battery stocks commanded 40-80x forward P/E. Today, even CATL's stock price is only 12% above its previous high — and most others are still 30-80% below those peaks, trading at 15-25x 2027 estimates.

Widespread re-rating isn't in the cards unless rates fall dramatically. Returns will come from profit delivery, utilization rates, and cash flow quality — not multiple expansion.

Concentration: A Warning Sign

Wet separator CR3 has fallen from 76% to 66%, and CR5 from 89% to 75%. LFP cathode concentration has also slipped. More players mean pricing power is more distributed. This isn't a call to short the industry — it's a call to be selective. Winners will need real advantages in cost, technology, customer relationships, and utilization.

The Trade: Interval-Based, Not Set-and-Forget

For materials and secondary battery producers:

• Buy during weak periods (oversold, low sentiment)
• Sell when expectations become crowded (positioned, optimistic)

For CATL: hold as the quality anchor. Trade other names around valuation, ASP expectations, and EPS correction momentum.

The battery cycle has returned — but it's a different beast this time. Adapt or get left behind.
