The　nickel　cobalt　manganese　ternary　(NCM)　cathode　material　is　one　of　the　important　parts　of　power　lithium　battery.　The　NCM　cathode　material　production　process　including　the　Li2CO3　preparation,　precursor　preparation　and　synthesis　process　of　cathode　materials　is　resource-and　energy-intensive,　thus　it　leads　to　relatively　severe　environment　pollution.　In　this　article,　life　cycle　assessment　of　NCM　cathode　material　production　using　coprecipitation　method　in　China　was　conducted　based　on　ReCiPe　method.　The　environmental　impacts　of　the　main　processes　were　calculated.　The　main　factors　and　sources　causing　environmental　pressure　were　identified.　The　results　indicated　that　the　precursor　production　contributed　the　most　to　environmental　impacts　in　the　NCM　cathode　material　production.　The　energy　consumption　of　the　precursor　production　was　612MJ,　accounting　for　94.6%　of　the　total　energy　consumption　of　NCM　production.　The　environmental　impacts　of　the　CoSO4　production　and　NiSO4　production　were　the　main　contributors　to　that　of　the　precursor　production.　The　primary　cobalt　and　nickel　resources　in　China　with　lower　grade　and　difficult　mining　led　to　the　high　energy　consumption　of　these　two　kinds　of　raw　materials.　Therefore,　the　development　and　utilization　of　the　secondary　cobalt　and　nickel　metals　will　be　a　great　potential　to　reduce　environmental　impacts　of　NCM　production.　©　2020　Trans　Tech　Publications　Ltd,　Switzerland.
