Samsung SDI is a South Korean (Yongin, Gyeonggi-do) rechargeable-battery and electronic-materials manufacturer, and one of the world's largest lithium-ion cell producers.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 1 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
BMW Group's own 2019-11-21 press release: long-term supply contract worth EUR 2.9 billion for fifth-generation battery cells, deliveries 2021-2031. No share of either company's total sales disclosed.
Scope. Absence of a counterparty here is not evidence that none exists — 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.
5 other tracked dossiers name this company as a counterparty in its own sourced disclosure — 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: 997 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.
Historical cell partner via SB LiMotive, a 50:50 Bosch-Samsung SDI joint venture (2008-2012, cell fab in Ulsan, South Korea) developing and manufacturing lithium-ion batteries for hybrid/PHEV/EV applications. Dissolved 2012, with Samsung SDI reported to continue as a cell supplier while Bosch retained freedom to source from other manufacturers — but no primary Bosch or Samsung SDI disclosure confirms that residual relationship is still active today, hence secondary confidence (Wikipedia, not a company release). Distinct era/product from the CATL row above (48V-specific, live) — kept separate rather than merged.
BTR's Aug 2024 release lists Samsung SDI among major battery-maker customers (with Panasonic, LGES, SK On, CATL, BYD); no volume or share stated.
DAPA selected Hanwha Defense as prime for KSS-III Batch II AIP submarines in 2019; Samsung SDI supplies the lithium-ion battery packs for the class, first vessel (ROKS Jang Yeong-sil) launched Oct 2025.
First-ever EV battery supply agreement between the two companies, signed at a ceremony in Seoul 2026-04-20 (Samsung SDI CEO Joo Sun Choi; Mercedes-Benz Group Chair Ola Källenius) per Samsung SDI's own press release. High-nickel NCM cells for next-generation compact/mid-size EV SUVs and coupes. Samsung SDI's release does NOT state a contract value or volume — the widely-reported ~KRW 10 trillion (~USD 6.8bn)/tens-of-GWh figures trace to press/analyst estimates (e.g. Korea Herald, carboncredits.com), not to either company's own disclosure, so they are deliberately omitted here rather than repeated as fact.
Glencore press release (10 Feb 2020): 5-year agreement to supply Samsung SDI up to 21,000 tonnes of cobalt contained in cobalt hydroxide, sourced from Glencore's DRC operations, with annual RMI Cobalt Refinery Supply Chain audits. Contract term has since lapsed; no successor agreement found in this check.
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 — 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 company’s materials — 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.
