Zinc battery firm Eos Energy Enterprises saw reduced activity in Q2 as it transitioned to its Z3 product, while CEO Joe Mastrangelo discussed its backlog, the subject of a recent short-seller note.

US$137.4 million worth of customer orders have been booked so far this year by Eos Energy Enterprises and the zinc hybrid cathode battery storage company said that figure could reach US$300 million by the end of 2021.

Long-duration zinc battery energy storage system maker Eos Energy Enterprises’ order book, backlog and sales pipelines have greatly increased, but the company has also incurred significant costs as it puts in efforts to reach scale in manufacturing and deployments.
