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.,

Team develops high-capacity Li-ion sulfur battery; no Li-metal anode

Green Car Congress

ion battery using an enhanced sulfur–carbon composite cathode that exploits graphene carbon with a 3D array (3DG?S) based anode (Li y SiO x –C)—i.e. avoiding the use of a Li metal anode entirely. The Li y SiO x –C/3DG? cost and high?energy?storage Schematic representation of the lithium-ion sulfur cell.

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.)

DOE: cobalt is the most expensive material used in lithium-ion battery cathodes

Green Car Congress

Aside from the lithium needed to produce modern lithium-ion batteries, much attention is focused on the cost of the materials used for EV battery cathode production. Cobalt is an important ingredient in lithium-ion battery cathode production, accounting for about a quarter of the cost of the battery. Source: DOE.

Researchers in Belgium develop new class of solid composite electrolytes for Li-ion batteries: Eutectogels

Green Car Congress

Researchers at Hasselt University in Belgium are proposing a new class of solid composite electrolytes (SCEs) for Li-ion batteries: deep eutectic solvent (DES)–silica composites. These ETGs can be easily processed—potentially at lower costs—than ionic-liquid-based composite electrolytes. Joos et al. …
