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

Green Car Congress

Mass production of LIBs can result in environmental concerns during battery manufacturing and disposal. million kg per year of NMP is used for depositing the cathode layers for a battery manufacturing plant producing 100,000 packs per year of 60 kW, 10 kWh plug-in hybrid vehicle (PHEV) batteries. —Li et al.

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. Niobium and batteries. was published in the journal Nature in 2018. The paper (Griffith et al. )

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

Green Car Congress

With the accelerating transition to electric vehicles (EVs), demand for the materials used to produce batteries will increase significantly and rapidly. 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.

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

Green Car Congress

The “classic” high-energy capacity Lithium-sulfur battery is predicated on the use of a sulfur-based cathode and a Lithium-metal anode. 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. The Li y SiO x –C/3DG?

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. …
