In　order　to　evaluate　environmental　impact　of　cascade　utilization　fromlithium　iron　phosphate　(LFP)　batteries,　two　utilization　scenarios,　direct　utilization　scenario　and　cascade　utilization　scenario,　were　set　in　this　article.　The　environmental　impact　and　contribution　of　each　stage　in　both　of　utilization　scenarios　were　analyzed　based　on　life　cycle　assessment　(LCA)methodology.With　a　life　cycle　of　800times,　1GWh　LFP　battery　used　in　energy　storage　battery　for　the　communication　base　station　(CBS)　was　set　as　the　function　unit.　The　key　points　of　environmental　impact　from　the　two　utilization　scenarios　were　the　energy　storage　utilization　stage,　accounting　for　58.25%　and　64.03%　of　the　total　environmental　impact　respectively.　The　environmental　impact　from　the　manufacturing　stage　was　also　significant,　accounting　for　41.58%　and　27.36%,　respectively.　The　contribution　to　the　total　environmental　loads　from　the　recovery　and　regeneration　stage　was　0.18%　and　0.14%,　respectively.　The　environmental　benefits　fromthe　lithium　recycling　were　offset　by　the　environmental　loads　fromthe　additional　resources　and　energy　consumption　initsrecycling　process.　The　results　from　the　comparing　the　environmental　impactof　the　two　utilization　scenarios　revealed　that　the　cascade　utilization　scenario　reduced　the　total　environmental　impact　by9.03%,　which　is　more　environmentally　friendly　compared　to　the　direct　utilization　scenario.　Furthermore,　the　contribution　structuresof　the　resource　consumption,　energy　consumption　and　greenhouse　gases　emission　in　the　two　scenarios　were　analyzed.　The　results　indicated　that　the　manufacturing　stage　and　the　energy　storage　utilization　stagecontributed　significantly　to　these　three　indicators.　©　2022,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
