Sodium-Ion Batteries Hit Inflection Point, Analogous to Pre-Explosion of 2020 LFP

Overview

This report positions Contemporary Amperex Technology Co., Ltd. (CATL, 3750.HK) at the core of the sodium-ion battery industry explosion. The research note uses historical analogy to point out that the current technological maturity, supply chain readiness, and early-stage market penetration status of sodium-ion batteries are highly similar to lithium iron phosphate (LFP) batteries in 2020. As energy density breaks through key thresholds and cost advantages emerge, sodium-ion batteries are expected to replicate the S-shaped growth curve of LFP after 2021, becoming a significant incremental driver for mass-market electric vehicles and energy storage sectors. Based on this logic, the institution maintains an Overweight rating on CATL and is optimistic about its leading position in the new product cycle.

Core views

Historical Mirror and Inflection Judgment: The core view of the research note is 'Learn from history'. Between 2017-2019, LFP market share remained low due to受制 by subsidy policies because of low energy density (140-150Wh/kg). 2020 was a turning point; LFP energy density increased to 170-180Wh/kg, coupled with structural innovations such as CTP, breaking performance bottlenecks and regaining subsidy eligibility, followed by an explosion in 2021. China's market share surged from 4% in 2019 to over 70% in 2025. The research note believes today's sodium-ion batteries are in the same 'pre-explosion' phase: current installation volume is only about 2GWh, but energy density has reached ~175Wh/kg, sufficient to support initial deployment in entry-level electric vehicles, light trucks, and energy storage scenarios. Cost and Strategic Advantages: In addition to technical benchmarking, sodium-ion batteries possess unique advantages in cost and supply chain security. Raw materials are abundant and easy to acquire domestically, aligning with China's strategic direction of strengthening mineral security. The research note points out that sodium-ion batteries have already achieved cost parity with LFP, and there is an estimated 35% cost reduction space after scaling. This significant economic viability combined with better low-temperature performance and safety makes it possible under policy support and industry incentives to accelerate the transition from pilot deployment to large-scale adoption. Valuation and Rating Support: Based on the above industry trends, the research note maintains an 'Overweight' rating on CATL. The institution adopts the EV/EBITDA valuation method, assigning a 17x multiple to 2027 expected EBITDA (implying 2027 P/E ratio of 25.4x), and granting a 20% premium for H-shares. The latest target price is set at 815 HKD, offering 23% upside space compared to the current stock price. The report emphasizes that as an industry leader, CATL will be the first to benefit from the dividends of this new technology cycle.

Analysis framework

The research note mainly adopted 'Historical Analogy Analysis' and 'S-Curve Penetration Model'. First, by reviewing the trajectory of technical breakthroughs, policy adaptation, and market share changes of LFP batteries around 2020, a successful reference system was established. Second, mapping the current key indicators of sodium-ion batteries (such as energy density 175Wh/kg, small-scale installations, supply chain readiness) onto this reference system, arguing it is at the same eve of explosion. Additionally, combining supply-demand frameworks, analyzed the strategic significance of raw material localization for supply chain security, and the promotional role of cost reduction on popular market EV adoption, thereby deriving the future medium-to-long-term growth potential of sodium-ion batteries.

Methodology notes

• Industry/Industrial Analysis FrameworkPenetration Rate S-Curve

  S-Curve in Technology Adoption Lifecycle

  The report borrows historical data from LFP to illustrate that after a new technology breaks through critical points (such as energy density thresholds, cost parity), market penetration rate will shift from slow growth to exponential explosion, presenting an S-shaped trend. Sodium-ion batteries are considered to be in the stage of starting acceleration on the S-curve.

• Valuation MethodEV/EBITDA valuation

  Enterprise Value Multiple Valuation

  The report uses EV/EBITDA (Enterprise Value / Earnings Before Interest, Taxes, Depreciation, and Amortization) as the core valuation metric to maintain consistency with international peers. By applying a specific multiple to expected 2027 EBITDA, combined with H/A-share premiums, the target price is derived.
