RENO, Nev. — Agreement Details R&D Parameters for Aqua Metals to Convert LiNiCo’s Lithium-Ion Battery Black Mass into High-Value Metals RENO, Nev., Nov. 04, 2021-- Aqua Metals, Inc. (NASDAQ: AQMS) ("Aqua Metals" or the "Company"), a leading innovator in metals recycling with its AquaRefining™ technology, has signed a collaboration agreement with LINICO Corporation (“LiNiCo”), a cleantech innovator and aggregator focused on closed-loop lithium-ion battery recycling, to process lithium-ion battery black mass into high-quality metals. This agreement, which sets the parameters for future research and development cooperation, strengthens both companies’ expansion into lithium-ion battery recycling and builds on the two companies' commitment to advancing best-in-class technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LiNiCo plans to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the two companies announced earlier this year. LiNiCo will process the feedstock into high-quality black mass utilizing its proprietary process. The resulting black mass will be used as input feedstock for Aqua Metals’ AquaRefining pilot cells to create high purity metals such as nickel, cobalt, and copper as well as other compounds. AquaRefining, already proven at commercial grade for the clean recycling of lead-acid batteries, is a room temperature, water-based process that is fundamentally non-polluting and uses an electroplating process that builds metal by plating one atom at a time. Aqua Metals’ unique approach for multi-metal recovery for lithium-ion battery recycling is designed to recover a higher percentage of metals in a higher quality form, with better economics and lower emissions and waste streams than current recycling applications – all in a safe environment for workers.     “With the shift to the sustainable clean energy economy, we are facing a global challenge with the need to recycle an estimated 15 million tonnes of end-of-life lithium-ion batteries by 2030. As the world’s 1.4 billion cars transition to electric vehicles over time, it is imperative that we utilize innovative, clean lithium-ion battery recycling or risk undermining our environmental progress,” said Steve Cotton, President and CEO of Aqua Metals. “By working together, Aqua Metals and LiNiCo plan to provide a cost-effective and environmentally responsible solution for re-utilizing in country the scarce and expensive metals needed for lithium-ion batteries, instead of solely relying on mining strategic metals from out of country sources that can result in harsh environmental and social costs.” “We are pleased to collaborate with Aqua Metals to develop valuable recycled metals not only economically but also environmentally safe,” said Michael Vogel, President, CEO, and Founder of LiNiCo. “By utilizing the power of our proprietary innovative recycling technology that is already capable of receiving, crushing, and producing high purity black mass in our new recycling facility, combined with Aqua Metals’ proven AquaRefining technology, we believe our joint partnership will enable us to develop new methods to cost-effectively and sustainably recover high-quality metals in ways that will benefit the industry and the planet.” In February 2021, the Company and LiNiCo reached a lease-to-buy agreement for the Aqua Metals' 136,000 square foot AquaRefining facility for which LiNiCo made the first purchase deposit of $1.25 million in October, 2021. Aqua Metals also committed a $2 million investment, paid in Aqua Metals shares, for a 10% ownership in LiNiCo, as part of its strategy to strengthen growth by potentially applying AquaRefining™ intellectual property to lithium-ion battery recycling while meeting its lead recycling commercial guidance. The Company’s investment transaction was undertaken in partnership with Comstock Mining Inc. (NYSE: LODE), which secured the rights to a majority equity stake in LINICO.
