Indonesia — Building on its nickel downstream processing success, Indonesia is pursuing domestic EV battery cell manufacturing. LG Energy Solution's $9.8 billion joint venture with Hyundai includes a battery cell factory in Karawang, West Java. CATL is investing in a Sulawesi integrated facility linking nickel processing directly to cathode and cell production.
The ambition is a fully domestic supply chain: Indonesian nickel → Indonesian processing (HPAL) → Indonesian cathode materials → Indonesian battery cells → Indonesian EV assembly. If realized, this would be one of the most vertically integrated battery supply chains outside China. The missing pieces are electrolyte and separator production, still imported from Japan, Korea, and China.
The risk is that evolving battery chemistry threatens the nickel-based strategy. LFP (lithium iron phosphate) batteries, which use no nickel, are gaining market share in affordable EVs — exactly the segment most relevant to Indonesia's domestic market. If LFP dominance continues, Indonesia's nickel-to-battery strategy may be viable only for premium EVs while the mass market moves to nickel-free chemistries.
