Any remaining organic components are burned for energy recovery. Waste and byproducts can include: drosses, slags, so

The results of this work is a summary of the environmental impacts to enable decisions on how to minimize the net environmental impact across the product stream under study. Determ

Ideally, documentation should include quantitative accounting of materials and energy in and out, including

32、wastes and effluents, illustrated by flow charts. 4.7.2 Document battery production processes, up to installation in a vehicle. 4.7.3 Similarly, document battery recycling processes. Identify products and wastes. Document products in terms of purity and utility for feeding back into battery producti

33、on at a specified stage, or into another process. 4.7.4 Flag any potentially significant environmental impacts or material supply implications. The Argonne National Labs report prepared by Sullivan, J.L. Gaines, L. (2010) is a very comprehensive study that covers most battery types. The EPA Report #

34、 744-R-12-001 focuses specifically on lithium ion battery chemistry types. 4.8 Design for Recycle Recyclability must be considered early in the products engineering design/development process, to enhance the systems recyclability at the end of the batteries useful life. USABC Battery Recycling Worki

35、ng Group developed Recycling Design Guidelines to support this early design consideration. The guidelines provide recommendations to improve removability and access to the battery components. It is important that the battery components are easily separable into recycling streams (e.g. plastics, meta

36、ls, battery active materials, etc.). Additionally, the number of differing types of fastener sizes and plastic types should be minimized. Chemical adhesion such as epoxy, glues, and potting should be avoided, however when adhesives are necessary, non-thermosets should be used. The complete design fo
