Stars

High-nickel ternary cathode materials: Ronbay maintains dominant leadership in the premium EV segment with high-nickel (8-9-series) ternary cathodes. As of December 2025 the company holds a global market share exceeding 12% in ternary materials, marking its fourth consecutive year as the world leader. Shipments of ultra-high-nickel products (9-series) reached 27,000 tons in 2024, representing 23% of the company's total ternary volume. The ternary segment is being driven by accelerating adoption of 4680 large cylindrical batteries; industry forecasts project a market growth rate for relevant large-format battery cathodes at 19.4% CAGR through 2035. Strategic CAPEX is concentrated on the South Korea facility, where the 40,000 tons/year second phase entered trial production in early 2025 to serve international clients, with commercial ramp targeted throughout 2025-2026.

Lithium manganese iron phosphate (LMFP): LMFP is transitioning into a high-growth star as it penetrates mass-market automotive. Ronbay delivered a 100% year-on-year sales increase for LMFP in 2024, securing procurement orders equivalent to battery supply for thousands of vehicles from top-tier cell makers. Market projections for 2025 estimate LMFP penetration of 5-10% in the new energy vehicle (NEV) market, implying a segment size potentially surpassing RMB 10 billion (≈USD 1.4 billion) in 2025 alone. Ronbay's China LMFP capacity stands at 10,000 tons/year; a planned 20,000 tons/year LMFP facility in South Korea is designed to capture higher-margin overseas demand and to support OEM programs targeted at mid-priced EV segments with cycle-life and energy-density tradeoffs optimized for cost-sensitive models.

Sodium-ion cathode materials: Sodium-ion battery cathode materials have emerged as a high-potential star after a long-term strategic cooperation with CATL. Under the agreement Ronbay will supply over 60% of CATL's annual sodium-ion cathode procurement volume, with CATL planning large-scale application by end-2025. Ronbay has secured a confirmed 3,000-ton procurement order for layered oxide sodium-ion materials from downstream clients for delivery in the 2025 fiscal year. The company's 6,000 tons/year polyanion cathode facility in Xiantao is near full utilization, positioning the segment for rapid revenue contribution in 2025-2026. Sodium-ion advantages-lower raw material cost structure, better low-temperature performance, and improved safety-support a broader industry shift toward low-cost alternatives in grid and low-range EV applications.

Overseas market expansion (geographic star): International growth operates as a geographic star, driven by localized production and acquisitions of high-value global customers. Cumulative sales to overseas customers exceeded 20,000 tons for the first time in 2024. The South Korea base achieved profitability in Q4 2024. Ronbay targets a 20-30% share of the global cathode market by 2030, supported by the planned completion of its first European production phase in 2025. Revenue from international clients is growing faster than domestic sales; Ronbay now supplies five of the world's top six battery and EV manufacturers. This strategic tilt toward premium-priced global supply chains reduces exposure to domestic ternary price volatility, where average domestic ternary prices declined materially in 2024.

• Revenue and margin drivers: premium ternary (higher ASPs), LMFP scale in China and SK (cost-driven volumes), sodium-ion contracted volumes with CATL (volume visibility).
• Capacity allocation priorities: accelerate SK ternary ramp (40k tpa), expand LMFP SK capacity (20k tpa), optimize Xiantao polyanion utilization (6k tpa).
• Risk mitigants: diversify customer mix across five of top six global OEMs, shift sales mix to international premium contracts to offset domestic price declines.
• Financial implications: higher gross margins from premium ternary and international sales; 2024-2026 capex focused on South Korea and Europe with expected breakeven timelines of 12-24 months post-ramp.

Key performance indicators to monitor for Star segments include: global ternary market share (>12% target maintained), 9-series shipment growth (target +X% YoY to exceed 30k tpa by 2026), LMFP sales growth rate (target >100% YoY in 2025), sodium-ion contract fill rate (target >90% fulfillment of CATL volumes in 2025), overseas revenue growth rate (target >30% YoY), and utilization rates at new facilities (target >80% within 12 months of commercial start).

Ningbo Ronbay New Energy Technology Co., Ltd. (688005.SS) - BCG Matrix Analysis: Question Marks

Dogs - Question Marks

All-solid-state battery (ASSB) materials represent a high-growth question mark requiring significant R&D investment with uncertain commercial timelines. Ronbay's sulfide electrolyte pilot production line is scheduled for completion by end-2025, targeting a market still in industrialization verification. The company's ultra-high-nickel cathodes for solid-state batteries have received certification from multiple clients, yet industry forecasts project mass promotion of ASSBs in 2028-2030. In FY2024 Ronbay invested ≈¥175 million in strategic businesses including solid-state materials. Key technical challenges include high interface impedance and cell-level manufacturing scale-up; commercialization success depends on reducing interfacial resistance below target thresholds (industry targets: <100 Ω·cm2 for manufacturable interfaces) and demonstrating cycle life ≥1,000 cycles at ≥80% retention.

Lithium-rich manganese-based (LMR) cathode materials are a next-generation question mark with strong growth potential as the industry pursues cobalt-free, high-energy-density solutions. Ronbay reports validation-stage samples in trials with multiple domestic and international customers, with lab-scale composite cathodes showing up to ~86% energy density improvement relative to baseline NCM at equivalent mass loading in select tests. Current market share for LMR chemistry is low (internal estimate: single-digit % of Ronbay revenue; external market share for LMR globally: <1% of total cathode market as of 2024). The company has filed over 357 patents recently across multiple chemistries, indicating heavy IP defense. Commercialization timing for LMR is likely tied to the broader solid-state roadmap and may align with 2028-2030 adoption curves; near-term revenue contribution is minimal and requires scaling of stacked electrode manufacturing and thermal/structural stability improvements.

Humanoid robot battery applications are an early-stage, speculative question mark for Ronbay. The company is promoting cooperation with downstream humanoid robot clients and targeting markets requiring extreme gravimetric energy density and power output. As of December 2025 reported revenue contribution from robotics-targeted products is minimal (<1% of total revenue). The segment is characterized by very small current addressable market size but high potential growth if AI-driven robotics scale rapidly; the company identifies the low-altitude economy and robotics as new demand support points. Success depends on achieving specific energy >300 Wh/kg at application-relevant power pulses, fast charge capability, and rigorous safety under varied duty cycles.

Common strategic considerations and risks for the Question Marks quadrant at Ronbay:

• High R&D and capex intensity: FY2024 strategic spend ≈¥175 million plus ongoing pilot-scale capex.
• Commercial timing uncertainty: ASSB and LMR commercialization likely 2028-2030, creating multi-year revenue gap risk.
• Technical barriers: interface impedance for ASSB, cycling/thermal stability for LMR, and energy/power density for robotics applications.
• IP and competition: >357 patents filed by Ronbay, but intense competition from global battery material players could compress margins.
• Customer qualification cycles: long validation periods with OEMs and system integrators lengthen time-to-revenue.

Recommended monitoring metrics (operational KPIs):

• Pilot-to-demo throughput (kg/month) for sulfide electrolyte line; target ramp milestones through 2026.
• Cycle life and retention benchmarks for ASSB cells (target ≥1,000 cycles at ≥80% retention).
• Yield and scalability metrics for LMR electrode production (target >90% electrode coating yield at pilot scale).
• Number and status of commercial qualification agreements for humanoid robotics and ASSB OEMs (signed LOIs / paid trials).
• R&D expenditure run-rate versus roadmap milestones (quarterly spend and milestone achievement ratio).

Ningbo Ronbay New Energy Technology Co., Ltd. (688005.SS) - BCG Matrix Analysis: Dogs

Dogs

Legacy low-nickel and mid-nickel ternary materials have moved into the 'Dogs' quadrant as the battery materials market pivots toward high-nickel NCM/NCA chemistries and LFP/LMFP systems. Nationwide average prices for standard ternary materials declined by 79% year-on-year in early 2024, compressing gross margins and eroding relative market share for these mature products.

The company reported total revenue of 15.088 billion yuan for the 2024 fiscal year; the contribution from legacy low- and mid-nickel ternary product lines has been contracting as a percentage of this total, reflecting accelerating sales substitution toward the firm's 9-series and ultra-high-nickel offerings. These legacy lines generate low ROI and require ongoing management oversight disproportionate to their financial return.

Strategic responses include deprioritization of these chemistries and allocation of R&D, CAPEX and sales focus to high-margin, high-share 'Stars' such as the 9-series and ultra-high-nickel materials. Operationally, Ronbay is shifting production mix and channel efforts to stem cash erosion from low-margin SKUs.

Small-scale domestic precursor projects with persistently low capacity utilization are likewise classified as Dogs. The company has moved to phase out or consolidate these assets to improve capital efficiency and balance-sheet metrics. In April 2025 Ronbay announced a reduction in planned capacity for the '2025 Power-type Lithium Battery Material Comprehensive Base (Phase I)' from 0.06 million tons to 0.03 million tons.

The decision redirected 168 million yuan in remaining project funds to replenish working capital, signaling active divestment from underperforming domestic segments. The company is replacing legacy, small-scale domestic projects with larger, more efficient facilities in strategic locations such as South Korea to capture scale economies and higher utilization rates.

• Drivers of Dog status: severe price declines (-79% YoY), falling market share, low ROI, management resource drain.
• Actions taken: de-emphasize low/mid-nickel SKUs, scale down domestic precursor capacity, reallocate 168 million yuan to working capital, invest in high-nickel R&D and strategic overseas capacity.
• Financial impacts: shrinking revenue share from legacy lines within 15.088 billion yuan total (2024), margin dilution risk if legacy production continues at scale.

Operational implications include redirected CAPEX toward high-nickel 'Stars', consolidation of low-utilization domestic assets, and accelerated facility build-out in South Korea to replace legacy production with higher-efficiency, higher-utilization capacity that aligns with market growth vectors.
