Report on Critical Raw Materials and the Circular Economy

The list of Critical Raw Materials contains raw materials which reach or exceed thresholds for both economic importance and supply risk 6. The Commission established the first list in 2011 and committed to update it at least every three years to reflect market

The New Era of Sustainable Supply Chains

Investment activities are further highlighting the economic importance of sustainable sourcing. In September, blockchain-based product-tracking platform OpenSC (Sydney, Australia; ) — co-founded by the World Wide Fund for Nature and BCG Digital Ventures — received $4 million in seed funding to further develop its technology to trace, verify and share supply-chain data

Graphite

Essential commodities such as graphite and lithium have been at the forefront of market attention, given their importance as key inputs in the lithium-ion batteries used in EV production. As recently as a year ago, many bullish experts were predicting that graphite prices would escalate steadily into the 2020s in response to strong demand for both EVs and the production of fire-retardant

Graphene: A primer on the miracle material

2017/10/30But as Green Tech points out, a group of Chinese companies is planning to build "graphite megafactories" to produce 260,000 megatons of graphite anodes per year. Skating on thin graphene While graphite is brittle, when it is broken down into its constituent ingredients, the graphene material is virtually unbreakable – some say it's as hard as diamonds, or even harder.

Batteries fuel cells

A key raw material, both for the anodes of Li-ion batteries and bipolar plates in fuel cells, is carbon, made from natural graphite or in form of synthetic graphite based on petroleum coke. In Li-ion batteries, silicon, which is currently added at only 4-8% to increase battery capacity and shorten charging cycles, is also gaining importance.

Graphene/Gold Nanocomposites

In Figure 1(a), raw graphite has XRD diffraction peaks at 26.4, 44.3, and 54.5 corresponding to the hexagonal lattice of (002), (101), and (004) planes with an interplanar distance of 0.338 nm. After oxidation, the intense (002) peak of graphite powder disappears and an additional peak at 10.94 is observed, which corresponds to the (001) diffraction peak of graphene oxide.

Graphite Electrodes Market Size, Applications and

Needle coke is the primary raw material required for manufacturing ultra-high power graphite electrodes (UHP) and accounts for more than 40% of the total raw material cost. Division of the global graphite electrodes market into five major continents shows that Asia Pacific is at the leading position with the highest CAGR in 2018 making up 42.6% of the total market share.
