Battery materials manufacturer to idle portions of its US lithium production

Thu, 08/27/2020 - 16:57 -- Paul Crompton

Battery materials firm Albemarle is due to idle portions of its lithium mine and production facility in the US due to short-term supply-demand imbalances and an excess stockpile of battery-grade lithium.

The North Carolina-headquartered firm’s Silver Peak lithium mine in Nevada and Kings Mountain lithium hydroxide production facility in North Carolina are due to partially close next month until the end of the year.

EcoGraf tests show recovery of high purity battery anode material from lithium-ion battery materials.

Wed, 08/19/2020 - 15:39 -- Paul Crompton

Australian firm EcoGraf has claimed its proprietary purification process has been successfully applied to recycling battery materials from ‘production scrap’ and ‘black mass’.

In testing undertaken in collaboration with potential customers, the firm’s proprietary purification process has returned results of 98.6-100% carbon from production scrap and 98-99.6% from black mass.

Tests prove need for high purity alumina in making lithium-ion batteries last longer

Fri, 06/05/2020 - 12:31 -- Paul Crompton

Australian battery materials firm Altech Chemicals has released test results that show high purity (99.99%) 4N alumina prevents sodium leaching when used on a lithium-ion battery separator.

Test work by Germany’s Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) showed high purity alumina (HPA) could prevent battery failure modes including thermal runaway, lithium plating on the anode and life cycle reduction.

Anode material opens path to fast charging lithium-ion batteries

Fri, 03/27/2020 - 11:16 -- Paul Crompton

US scientists could provide insights into battery materials that allow the rapid charging of electric vehicles after making observations on how ions move in lithium titanate electrode material.

A team led by the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Lawrence Berkeley National Laboratory captured, in real time, how lithium ions move in the material (made of lithium, titanium, and oxygen).
