US Department of Energy promotes the development of battery recycling and rapid operation verification technology
Recently, the US Department of Energy (DOE) announced a number of information aimed at promoting the development of battery recycling and battery rapid operation verification technology. Details are as follows:

1. 335 million US dollars to support lithium ion battery recycling technology

On August 29, DOE released the project information and opinion collection, aiming to guide the implementation of the lithium ion battery recycling plan proposed in the Bipartisan Infrastructure Act, so as to strengthen the domestic battery recycling and establish a more sustainable battery supply chain. The total budget of the plan from 2022 to 2026 is 335 million dollars. Details are as follows: ① The budget for "battery recycling research, development and demonstration" is 60 million dollars; ② The budget of the "State and Local Plan" is 50 million dollars; ③ The budget of "retailers as recycling points" is 15 million dollars; ④ The budget of "Electric Vehicle Recycling and Reuse Plan" is 200 million dollars. DOE focuses on the following areas for public consultation: ① Collection of lithium ion batteries and manufacturing wastes; ② Transportation of lithium ion battery and manufacturing waste; ③ Classification of lithium ion batteries in the recovery stream; ④ Treatment of lithium ion battery and manufacturing waste; ⑤ Manufacturing/processing facility license; ⑥ Secondary use of lithium ion battery; ⑦ State and local collection plans for lithium-ion batteries; ⑧ Lithium ion battery retail collection plan; ⑨ Expand the participation of trade unions; ⑩ Equity, environment and energy justice priorities.

2. Rapid operation verification of liquid flow battery

On September 1, DOE National Energy Technology Laboratory issued a bid to accelerate the testing and verification of new energy storage batteries, such as liquid flow batteries, by launching the Rapid Operation Verification Program (ROVI), and solve the key data needs in technology development. The plan will establish a data collection and analysis framework to determine the basic data requirements of different long-term energy storage technologies, and then develop protocols to ensure that data can be collected and stored in a standardized format. In addition, ROVI will provide a platform for project executors to collect data from real systems and use methods such as artificial intelligence and machine learning to obtain predictive performance. The goal of the plan is to use data-driven methods to develop new technologies to accelerate testing and verification methods, so that test data that takes only one year or less can predict technical performance for more than 15 years.
