Tesla scaling battery cell production, lithium refinery, cathode refinery, and solar cell production in-house for electrification and AI infrastructure
Elon Musk· Tesla / SpaceX / xAI· Robotics· 2026-04-23· about Tesla (TSLA)
“we're scaling up battery cell productions battery cell production and we're also preparing to do a massive solar panel like solar cells and panel production. Actually this is going all the way from silicon refinement to producing the solar cell and then deployment of solar... There's going to be tremendous need for electricity in the future due to electrification of transport and and AI”
Why it matters
Tesla is vertically integrating critical raw materials and energy production (lithium, cathodes, battery cells, silicon, solar) to ensure supply security for massive expansion in EVs and AI infrastructure.
Investment implication
Suppliers of lithium mining equipment, refining equipment, battery manufacturing gear, and solar production tools may lose business to Tesla vertical integration. Materials suppliers (lithium, silicon) should expect increased competition from Tesla's in-house refineries.
