Leading Edge Materials hails Woxna spheronization test results

The company said more than 10 kgs of spheronised material was produced, which will be purified to battery grade and used in lithium ion battery cell testing

Leading Edge Materials Corp (CVE:LEM, OTCQB:LEMIF) unveiled positive spheronization test results from graphite from its Woxna mine in Sweden.

As previously reported, Leading Edge Materials is undertaking research and development (R&D) to support the design and installation of a battery graphite demonstration plant at the site.

Spheronization (also known as spheroidisation) is a milling and shaping process to reduce the size of graphite flakes while shaping the flakes in an elongate spheroid.

The aim is to optimise the particle surface area to achieve the highest performance in the anode (battery material).

"More than 10 kgs of spheronised material was produced, which will be purified to battery grade and used in lithium ion battery cell testing," the firm said in a regulatory statement today.

"As Leading Edge Materials is a member of the EU Battery Alliance, the company has access to a comprehensive customer network, which is being used to deliver European sourced natural graphite anode material for testing by the emerging European battery industry."

Scanning Electron Microscope imagery of the spheronised product showed grain morphology to be "well rounded, smooth and without particle agglomeration, in line with current commercial natural graphite anode products," said LEM.

"This spheronising optimization research using commercial equipment has produced excellent graphite grain morphology, in line with similar products that are consumed by the lithium ion battery industry today," said Blair Way, president and CEO of Leading Edge.

"This work is providing the bank of data required for design of the Woxna Battery Graphite Demonstration Plant which will allow customer qualification of both our anode manufacturing process and the anode product".

LEM added that test programs were continuing, and further spheronizing and purification results are expected next month.

LEM shares in Toronto eased 1.49% to $0.33.
