CALB Group (formerly China Aviation Lithium Battery; HKG: 3931), headquartered in Changzhou, Jiangsu, is the world's 4th-largest EV battery supplier by volume (62.8 GWh installed, 5.3% global share, full-year 2025 per SNE Research) and China's 3rd-largest behind CATL and BYD, supplying EV traction cells and stationary energy-storage systems.
Two independent sources (The China Project, Wikipedia) confirm AVIC was reduced to a ~10% minority stake and that a Changzhou-government-controlled entity holds control following the 2017 buyout, but neither gives a current precise stake % for the Changzhou vehicle post-2022-IPO, and a 2026-08 search of HKEX/secondary-aggregator shareholder pages did not surface one either (MarketScreener/Simply Wall St report only that 'private companies' hold 47% and the top-5 hold 51%, without naming holders) โ flagged for direct confirmation against CALB's HKEX shareholder-register filing next pass rather than guessed. GLEIF has no LEI record for CALB Group / CALB Co. / China Aviation Lithium Battery under any name variant tried (checked 2026-08-28) โ no lei: field set. No dossier exists in this corpus for AVIC or any Changzhou state investment vehicle, so parent_slug is not set; CALB is not a subsidiary of any other corpus company.
Named counterparties identified by open-source research and written only where a primary source states the relationship โ never inferred from sector or co-mention. 2 suppliers, 3 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
CnEVPost reporting (citing installation data) says CALB became XPeng's largest battery supplier in H1 2023 and supplies LFP/ternary cells for the XPeng G6; no CALB-side revenue share disclosed, so no share_pct written.
FY2024 annual report, note 47(b): RMB 2,858.909m of 'entrusted processing services' bought from Luoyang Company (annual cap RMB 3,000m; CCT section states ~RMB 2,858.91m), +46.2% on FY2023's RMB 1,956.184m. Luoyang Company is owned 51% by Jincheng Technology (wholly owned by Jintan Holding, a 26.02% CALB shareholder) and 49% by Jinhang Holding, hence a connected person; the Directors' Report names it as one of CALB's five largest suppliers, without stating its rank or share (top-5 suppliers = 40.1%, largest single supplier 11.5%). Toll-manufacturing of finished lithium batteries with Luoyang supplying raw materials, labour and technicians โ a captive capacity arrangement, not arm's-length raw-material supply. No share_pct: the filing gives no purchase-total denominator for this line. 2026-09-27: source URL swapped www->www1 host after www.hkexnews.hk returned 503 on this pass; www1 mirror confirmed live (same PDF, 6.6MB, HTTP 200).
Prior-year comparative in the same FY2024 filing (note 47(b)): entrusted processing services from Luoyang Company RMB 1,956.184m in FY2023.
FY2024 annual report, note 47(b): RMB 1,245.564m revenue from sales of goods to Luoyang Company, 7.6x FY2023's RMB 163.961m. The Sales Framework Agreement section gives ~RMB 1,263.54m (annual cap RMB 1,400m), the wider figure including Luoyang's associates. Batteries components, raw materials, work-in-progress and finished goods sold to the same entity that toll-processes CALB's cells โ a two-way loop, both roles related-party. No share_pct written: revenue denominator not captured this pass.
Prior-year comparative in the same FY2024 filing (note 47(b)): RMB 163.961m of sales of goods to Luoyang Company in FY2023.
Scope. Absence of a counterparty here is not evidence that none exists โ most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
4 other tracked dossiers name this company as a counterparty in its own sourced disclosure โ this platform never wrote these rows on this company's own page, they are read here inverted from the dossier that disclosed them. This is a partial view: 1004 additional named-counterparty rows across the corpus could not be matched to a tracked dossier by name at all (mostly non-Latin legal names), so the true count is higher than what renders here.
CALB supplies high-energy-density NMC lithium-ion cells integrated into Forsee Power's battery systems for electric commercial vehicles; CALB was the first Forsee Power supplier to complete the company's new ESG due-diligence audit (Bureau Veritas, Dec 2022).
Named as a supply-chain entry in the low-altitude-economy (eVTOL/drone) segment. Qualification-stage language; no volume disclosed.
Status upgrade from the FY2025 row: FY2025 described CALB as a 'qualification-stage' low-altitude-economy (eVTOL) entry; H1-2026 states mass production (้ไบง) has been achieved for CALB and Zhejiang Jinyu as eVTOL customers. No volume disclosed.
Scope. This section is inverted evidence: each linked dossier wrote the original row about itself, describing its own relationship to this company. It is never a claim this company itself disclosed. Absence here is not evidence of no relationship โ most of the corpus has no named-counterparty block at all yet.
Every exposure is read as a buyer dependency; the top 3 are its binding chokepoints.
As a buyer, policy pressure across its consumed materials is flat.
Descriptive trend in official policy actions on this companyโs materials โ a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
No actions in the register have named or swept this company in the last 24 months.
