whether there will be demand for their materials — there will be — but
whether Brazil can capture value beyond raw-material exports.¹

structurally favourable position for the 2026-2030 window.

battery cells require.²
downstream battery manufacturing capacity. There are no commercial-scale
lithium hydroxide refineries, no battery-grade nickel-sulfate or
cobalt-sulfate plants at scale, no sintered rare-earth magnet
production, and no domestic gigafactory. Battery cells for the Brazilian
electric-vehicle market are predominantly imported, typically from
Chinese, Korean or European manufacturers.

industrial capacity in battery chemicals and cell manufacturing has not
received the investment that analogous Asian economies have made. The
question is whether that pattern changes during the current investment
cycle.
