Leading Edge Materials Provides Update on High Purity Battery
Graphite Qualification from the Woxna Project, Sweden
Vancouver, Canada – Leading Edge Materials Corp . (“Leading Edge Materials”) or (the Company”)
(TSXV:LEM) (OTCQB: LEMIF) is pleased to announce test results from ten 18650 lithium ion battery
cells manufactured using high purity graphite from the Company’s Woxna mine and processing facility
in Sweden. 18650 battery cells are the “industry standard” for testing battery performance, equivalent
to those manufactured by Panasonic and used in Tesla electric vehicles.
Production of 18650 format cells has enabled a more comprehensive test of the performance of Woxna
high purity graphite in lithium ion batteries. The batteries bearing Woxna graphite were tested using
High Precision Coulometry (“HPC”) to measure an ode performance and stability under “real-world”
conditions. Test results are positive and encour age LEM to proceed further with battery material
qualification. The next stage of testing will in clude expanded 18650 battery cell manufacture and
undertaking more exhaustive material and performance testing.
Highlights of the latest test work include:
Strong and consistent battery cell capacity over 2 Ah
High coulombic efficiency (CE) trending over 99%
Excellent results for natural flake graphite anode materials
Blair Way, President and CEO, stated “It is rewarding to see the progress made in the testing of our
Woxna graphite for the lithium ion battery market. 18650 cells were manufactured using over 4kg of
Woxna high purity graphite, and provide the best test of graphite anode performance under real world
conditions, well beyond the testing possible on smaller coin cells. The HPC test results are encouraging
and I look forward to continuing this qualification process.”
A large quantity of commercial graphite flotation concentrate from the Woxna mine in Sweden was
shipped to an independent laboratory in the United States for spheronising and thermal purification.
This high purity graphite was used to produce anode material for the manufacture of 18650 battery
cells. These cells were tested with HPC to esti mate the cell life cycle capability. HPC measures
coulombic efficiency (“CE”) which is the loss of electrons per cycle, by accurately measuring the charge
delivered during discharge against the charge stored during charging. The closer the coulombic
efficiency gets to 100% the longer the life of the battery. At 100% CE the battery life is infinite, which
has not been achieved to date in any lithium ion battery. The company will provide further updates as
test work and qualification progresses.

results. Such statements involve known and unknown risks, uncertainties and other fact ors that may cause actual
results, performance or achievements to be materially different from those implied by such statements. Such
statements include but are not limited to, the Company’s expectations regarding graphite production at Woxna, the
Company’s preliminary economic assessment on Woxna is no longer current or valid as a result of the filing of a
new NI 43-101 Technical Report effective March 24, 2015, and the Company has no plans to complete a new
preliminary economic assessment, a pre-feasibility or feasibilit y study on the project, as such there is an increased
risk of technical and economic failure for the Woxna graphite project; unexpected geological conditions; exploration
activities to advance other critical material projects of the Company for energy storage markets, delays in obtaining
or failure to obtain necessary permits and approvals from government authorities. Al though such statements are
based on management's reasonable assumptions, there ar e risk factors which could cause the Company's actual
results, performance or achievements to be materially different from any future results, performance or
