Abstract: This sourcing intelligence project analyzes global suppliers for lithium-ion battery cells for Tesla, a critical component for its EV production. It identifies top suppliers using SCData.ai tools based on technical, financial, and sustainability metrics. The objective is to enhance Tesla’s battery supply chain resilience, cost efficiency, and ESG compliance.
Global Supplier Selection for Lithium-ion Battery Cells – Tesla
Author Parveen
Research Objective
To identify and recommend the most suitable global suppliers of lithium-ion battery cells for Tesla’s expanding EV manufacturing needs. The analysis aims to ensure quality, cost competitiveness, innovation, and ESG alignment with Tesla’s sustainability and production strategies.
Tesla’s Sourcing Priorities
Tesla aims to reduce cost per kWh while maintaining high energy density.
It is scaling production of the 4680 battery cell format.
Vertical integration at Gigafactories increases the need for dependable upstream suppliers.
Strategic goals include:
Cost savings from global sourcing
Supply chain risk reduction
Carbon-neutral production
Technology innovation and patent access
Supplier Selection Criteria
Based on Tesla’s priorities, the following criteria are defined (5-point scale for scoring):
Cost Efficiency – Price per kWh, volume discounts
Quality & Innovation – Product performance, patents, R&D investment
Production Capacity – Ability to meet volume at Gigafactory scale
Financial Health – Profitability, solvency, investment strength
Sustainability (ESG) – Emissions, compliance with battery recycling mandates
Supplier Comparison for Tesla
LG Energy shows balanced strengths across all value drivers, making it the most suitable primary supplier. CATL is strongest in cost and capacity but lags in ESG. Northvolt excels in ESG and innovation but has scale limitations. Based on this analysis, LG and CATL are recommended for Tesla’s dual-sourcing strategy.

Scoring Notes:
CATL leads in scale, cost, and innovation, but faces ESG and geopolitical scrutiny as a designated ‘Chinese military company’ by U.S. agencies Wall Street Journal+15Wikipedia+15Wikipedia+15Business Insider.
LG Energy Solution has high-quality output and financial strength and now avoids China-related tariffs via U.S. production floors. Tesla has signed a $4.3B LFP cell deal for its storage business, likely led by LGES electrive.com+6Reuters+6Barron's+6.
Panasonic is technically reliable and historically trusted by Tesla, manufacturing Tesla’s 4680 cylindrical cells in Kansas. The company lags in volume and cost advantage InsideEVs+1Investors.com+1.
EVE Energy is an emergent ESS supplier with a confirmed recent Tesla partnership; growing but still limited in scale and global ESG transparency
Best-in-class scale, cost, and technical innovation.
Strategic alliance potential and global manufacturing footprint.
⚠️ Manage geopolitical risk carefully as U.S. compliance may restrict future contracts.
Strong financial health, U.S.-based production to avoid tariffs, and expanding partnership with Tesla ($4.3 B LFP deal) electrive.com+6Reuters+6Wall Street Journal+6.
Balanced performance across all key dimensions.
Trusted reliability with experience producing Tesla’s cells.
Good ESG rating and strategic alignment.
Limited scale compared to CATL and LG.
Well-positioned in energy storage systems.
Low-cost supplier and confirmed Tesla ESS partner.
Best used as a supplementary partner for Megapack/Powerwall units.
