Manufacturers from China supply most lithium‑ion batteries deployed across global electric‑vehicle fleets and grid‑scale energy‑storage plants. Per data released by the Ministry of Industry and Information Technology, domestic lithium battery output reached 1,170 GWh in 2024. Chinese manufacturers supply over 80% of the global market share for core raw materials including cathode/anode materials, electrolytes and separators — the entire battery supply chain is centered in China.

Meanwhile, carbon footprint documentation has shifted from an optional report to a mandatory component of battery product compliance. The EU Battery Regulation enforces carbon footprint declarations with progressively tightening emission thresholds, while Digital Product Passports (DPP) are being rolled out for battery goods. For cross-border market access, batteries must come with verified carbon footprint records covering every upstream production stage.

Carbon footprint calculations span the full value chain: identical battery products can deliver drastically different emission results based on production location and manufacturing route.

The primary pain point lies in a mismatch between available datasets and China’s domestic industrial reality. Most carbon accounting workflows still rely on generic overseas databases or regional default values, which suffer from limited lithium battery entries, outdated data vintages, and modeling built around European energy mixes and production workflows. Even basic “China-wide industry average” datasets were unavailable for many upstream segments in past years. Calculating emissions for Chinese-manufactured batteries using foreign average values inherently produces unrepresentative, unreliable results.

The China Lithium Battery Carbon Footprint Database v1.1.0 is now live on the HiQLCD life cycle data platform. Co-developed by HiQLCD, the China Electronics Standardization Institute, Tsinghua University, Kunming University of Science and Technology, and Beijing CESI Certification Co., Ltd., this release delivers 519 Life Cycle Inventory (LCI) datasets covering 180 distinct product categories. Based on publicly available industry records, this represents the world’s most comprehensively covered full-value-chain carbon footprint database for lithium batteries.The core logic is straightforward: the vast majority of global lithium batteries are produced in China. A credible life cycle database for this sector must be built around China’s unique production locations, manufacturing workflows and supply chain conditions to deliver internationally recognized, representative results.

This database is designed not merely as a reference library for academic research, but as industrial-grade carbon accounting infrastructure fully integrable into corporate operational workflows. Its three distinct competitive advantages are outlined below:

Advantage 1: Separate Modeling by Production Origin & Manufacturing Route

Traditional background datasets only provide a single aggregated industry average for each material type. While these broad averages suffice for preliminary screening and rough estimation, they cannot be mapped to specific real-world supply chains — and for many lithium battery segments, reliable China-specific averages were previously unavailable.

Rather than only supplementing a single national average figure, this database delivers granular, segmented results answering a targeted question: what emission factors apply to your exact material source and production process?

The 519 datasets spanning 180 products mean multiple unique entries exist for the same material, with independent modeling split by geographic origin, manufacturing technology and market context. Instead of assigning one uniform average value to all batteries, every distinct supply chain receives its corresponding tailored emission profile.

Taking lithium carbonate as an example: the database separately models four production pathways including brine electrodialysis, adsorption lithium extraction, spodumene/lepidolite sulfuric acid roasting, and hybrid mixed technologies. Users select datasets matching the exact lithium production route deployed in their supply chain.

Geographic segmentation is equally robust. Beyond aggregated national Chinese averages, critical mineral and chemical datasets covering lithium, cobalt, nickel, manganese and graphite include provincial-level breakdowns across 16 major production hubs such as Jiangxi, Sichuan, Hunan, Yunnan and Shanxi. Emission profiles differ across provinces due to divergent local energy mixes and factory operating conditions.

Advantage 2: End-to-End CoveragefFrom Ore Extraction to Complete Battery Packs

The 519 released datasets span the complete lithium battery value chain:

Upstream mineral & concentrate extraction (lithium, cobalt, nickel, manganese, graphite)
Battery-grade chemical intermediates (lithium carbonate, nickel sulfate, etc.)
Core electrode materials (LFP, NCM ternary cathodes, synthetic graphite anodes)
Auxiliary components (electrolytes, copper/aluminum foil, aluminum plastic film separators)
Finished cells, battery packs, BMS and supporting system components

Battery Passport compliance demands full cradle-to-gate carbon traceability. The database delivers matching background data for every tier of upstream material breakdown required during product-level carbon footprint auditing.

Advantage 3: New Datasets with Native LCA Software Compatibility

All datasets are built on verified real-world factory operational data cross-validated across multiple industrial sources; over 85% of inventory records draw on post-2020 production measurements — a critical quality benchmark for the fast-evolving lithium battery sector.

Methodology adheres to ISO 14040 and ISO 14044 standards via unit-process modeling, with fully traceable, auditable records for every production stage.

Each entry includes complete LCI inventory data and pre-calculated LCIA carbon footprint factors under cut-off system boundaries, covering both production mix and consumption mix modeling variants. All datasets follow the ILCD data specification with full supporting documentation, enabling direct import into mainstream LCA modeling software without additional data reformatting.

This defines what “industrial-grade” infrastructure means: grounded in real manufacturing metrics, fully traceable process records, software-native formatting, supply chain-aligned granularity, and regularly updated inventories matching rapid industry technological iteration. It functions as a purpose-built foundational tool for daily carbon accounting workflows, rather than a standalone reference document.

Target User Groups

1. Cell, battery pack and energy storage system manufacturers

Battery Passport audits require tiered upstream carbon tracing, supported by fully verifiable background datasets. Users can identify high-emission material segments and conduct comparative analysis across different raw material sources, production locations and manufacturing technologies.

2. Lithium mineral, lithium salt and battery material suppliers

Supports product carbon footprint reporting and LCA modeling, enables cross-process performance benchmarking, fills upstream data gaps, and meets carbon disclosure requirements from downstream OEM clients.

3. Vehicle OEMs, energy storage operators and supply chain procurement teams

Facilitates BOM-level carbon impact analysis, supply chain emission hotspot identification and comparative procurement scenario modeling.

Important Disclaimer

Industry background databases provide foundational modeling inputs and do not automatically equate to final verified carbon footprint results for individual products, nor do they guarantee automatic compliance with regulatory or certification requirements. They cannot replace primary on-site production data collected directly from manufacturing facilities. End-user applicability must be assessed separately based on project-specific functional units, system boundaries, data quality standards and third-party audit criteria.

How these 519 Datasets are Developed

Valid LCI records cannot be extracted purely from academic literature. Each dataset undergoes a rigorous end-to-end workflow: on-site factory data collection, cross-value-chain industrial research, unit-process modeling, multi-source cross-verification, and standardized formatting per ILCD specifications for LCA software compatibility. Every entry is refined through iterative industrial validation.

Data development specialists must possess deep domain expertise across the full battery supply chain — distinguishing emission gaps between brine and hard-rock lithium extraction, identifying energy-intensive production stages, and validating or adjusting self-reported factory operational metrics. This database is built with collective expertise from standards bodies, certification authorities and carbon data specialists.

Building an equivalent dataset library in-house would require assembling a cross-functional team combining LCA expertise and lithium battery manufacturing knowledge, conducting on-site industrial surveys, and establishing dedicated modeling and quality control workflows. This multi-year investment is impractical for most individual enterprises.

The 519 datasets represent two layers of accumulated value: verified real-world operational metrics captured across the full battery supply chain, and aggregated technical judgment from a cohort of senior industry specialists. Access to a pre-built standardized industry database drastically reduces internal resource and timeline burdens for corporate carbon teams.
