UVA researchers devise method for converting retired Li-ion anodes to graphene and GO

Green Car Congress

Researchers at the University of Virginia (UVA) have devised a process for converting retired Li-ion battery anodes to graphene and graphene oxide (GO). So far, only 1% of end-of-life Li-ion batteries have been recycled. Here, graphite powders from end-of-life Li-ion battery anodes were used to fabricate graphene. .

Virginia Tech team demonstrates green manufacturing method for Li-ion batteries

Green Car Congress

Given that the global lithium-ion battery production capability is ~400 GWh, humongous amount of NMP is needed. NMP is expensive and reprotoxic and has been added to the restricted substances list by the European Commission in 2018. —Li et al. —Li et al. Jianlin Li, Yingqi Lu, Tairan Yang, Dayang Ge, David L.

Roskill: Niobium industry looking for a future beyond steel; Li-ion batteries a possibility

Green Car Congress

However, the spike in vanadium prices (ferrovanadium prices increased by about 200% in 2018) caused Chinese mills to substitute niobium to vanadium and Chinese niobium imports increased 30% year-on-year both in 2018 and 2019. was published in the journal Nature in 2018. The paper (Griffith et al. ) Griffith et al. Griffith, K.J.,

Roskill: record cobalt deals in Q1 2018 show raw material procurement for Li-ion batteries revving up

Green Car Congress

There is now a significant wave of interest in battery raw material supply security, mainly from Asia, to underpin the growth of Li-ion battery production over the next decade. In March 2018, Chinese high-tech recycling giant GEM signed a three-year cobalt supply agreement with Swiss miner Glencore. Earlier post.)
