PPES is a battery production company established through a joint investment between Toyota, the world’s largest automaker by revenue, and Panasonic, a leading battery manufacturer.

Under the agreement, ioneer will deliver 4,000 tonnes per annum (tpa) of lithium carbonate to PPES over a period of 5 years. PPES will use ioneer’s lithium carbonate to produce batteries for US electric vehicles.

ioneer is expected to produce an annual average of approximately 20,600 tonnes of lithium carbonate/hydroxide as well as approximately 174,400 tonnes of boric acid per year over the 26-year life of the Rhyolite Ridge project1. Dual production of lithium and boric acid allows ioneer to not only produce lithium in the United States, but to do so at the very bottom of the global cost curve. ioneer plans to start production in 2025 to meet urgent battery material needs in United States.

This agreement follows the two previous binding direct debit agreements2.3 and, in aggregate, represents the completion of the pre-production lithium carbonate supply commitments it currently intends to make for Rhyolite Ridge.

Key terms of the agreement with PPES include:

  • Product: lithium carbonate
  • Contract duration: 5 years
  • Volume: 4,000 tons per year
  • Price: Adjusted quarterly based on agreed pricing formula
