Batteries are half the business case for any electric car. For Hyundai, Kia, and several global brands, a huge share of that equation runs through LG Energy Solution (LGES) - one of the world's largest battery makers and Korea's flagship cell supplier.
Key takeaways
- LGES supplies NCM (nickel-cobalt-manganese) and other chemistries to automakers worldwide.
- HLI Green Power in Indonesia - a Hyundai-LGES JV - produces cells for models like the Kia EV3.
- A Georgia, USA JV (30 GWh/year) targets IRA-compliant supply for North American-built Hyundai, Kia, and Genesis EVs.
- Korean battery strategy balances energy density, subsidies, and supply-chain diversification away from China-only sourcing.
- Mass-market EV recovery in 2025-2026 depends partly on affordable NCM packs, not only LFP.
Who is LG Energy Solution?
LG Energy Solution spun out of LG Chem and supplies cells to automakers including General Motors, Hyundai Motor Group, Tesla (historically), and others. It competes globally with CATL, BYD FinDreams, Panasonic, and Samsung SDI.
For Korean automakers, LGES is the default strategic partner - similar to how Panasonic long anchored Tesla's early growth.
Key joint ventures
HLI Green Power - Indonesia
| Detail | Info |
|---|---|
| Partners | Hyundai Motor Group + LG Energy Solution |
| Location | Karawang, West Java |
| Capacity | 10 GWh initial phase; expansion planned |
| Significance | Indonesia's first EV battery cell plant; nickel supply chain access |
The plant supports models moving into mass-market segments. The Kia EV3 uses advanced NCM cells from this supply chain - notable because NCM was traditionally reserved for more expensive cars.
Why Indonesia? Nickel. Battery-grade nickel processing is concentrated in the region, and localizing cells reduces shipping cost and geopolitical risk.
Georgia, USA - Hyundai + LGES
| Detail | Info |
|---|---|
| Investment | ~$4.3 billion (announced 2023) |
| Capacity | 30 GWh per year (~300,000 EVs) |
| Location | Bryan County, Georgia - adjacent to Hyundai Metaplant America |
| Production target | End of 2025 onward |
This plant exists largely because of the U.S. Inflation Reduction Act (IRA), which ties EV tax credits to North American assembly and battery sourcing rules. Hyundai and Kia needed U.S.-built cells to stay competitive on price after early IRA disadvantages.
NCM vs LFP: Korea's bet
China's mass market runs on LFP. Korea's suppliers historically led on NCM for higher energy density - important for longer range in the same pack size.
LGES is pushing price-competitive NCM into cheaper EVs (EV3, Equinox EV, etc.). That lets Korean brands:
- Avoid total dependence on Chinese LFP imports
- Hit higher energy density targets for subsidies in Korea that favor advanced packs
- Differentiate on range in compact SUVs
2026 outlook
LGES executives have publicly tied a battery market rebound to new mass-market EV launches from partners like GM and Hyundai. When EV demand softened in 2024, battery makers felt it first. The 2025-2026 wave of affordable models is the turnaround bet.
Solid-state and advanced chemistries remain in development, but NCM and LFP improvements pay the bills this decade.
What readers should remember
When you read "Kia EV3 uses Korean batteries," that often means a global supply chain: Indonesian nickel, Korean engineering, local assembly, and regional packs tuned for regulations.
LGES is not a household name like Tesla - but it is one of the companies deciding whether your next EV qualifies for a tax credit, hits 300 miles of range, or ships on time.
Bottom line
Korean EV competitiveness in 2026 is inseparable from LG Energy Solution's factory map. Indonesia for cost and materials, America for IRA compliance, Korea for R&D - that triangle shapes Hyundai and Kia's electric future.
