The company has developed a graphene-type carbon material called C-Hemp carbon derived from hemp that shows superior performance compared to commercial carbon materials used in ultracapacitors. Testing indicates C-Hemp carbon can provide over 30% more energy and a 32% cost reduction per ultracapacitor cell. The company is seeking capital to further develop C-Hemp carbon and scale up production to commercialize their high performance, low cost graphene alternative for the energy storage market.

4. BATTERY vs ULTRACAPACITOR
Ultracapacitors are all about power, unlimited cycling, safety and predictable life. This is highly reliable short
term energy storage. Ultracapacitors are at least 10 times less expensive than batteries for frequent cycling
applications. Graphene-type materials can improve their performance significantly in terms of energy, power and
cost – see next slides
PARAMETER BATTERY ULTRACAPACITOR
Energy Density 100Wh/kg 10Wh/kg
Power Density 1kW/kg 10kW/kg
Efficiency ~80% >90%
Cyclability 400 – 2500 1,000,000
Calendar life Short (4..6 years) Long (15+ years)
Low Temperature -20°C -40°C
High Temperature +60°C +85°C
Death Sudden Predictable
Principle Electrochemical Electrostatic
Cost 0.07 - 0.2 $/kWh/cycle $0.006 $/kWh/ cycle

5. MARKET NICHES – HIGH POWER APPLICATIONS
▶ Hybrid and PHEV vehicles (buses, cars, light trains)
▶ Start / stop and energy recovery systems for hybrid cars
▶ Large engine cold cranking (heavy duty trucks, diesel locomotives, etc)
▶ Wind and solar power
▶ Frequency support and peak saving in electrical grids
▶ Emergency backup
▶ Defense applications (laser, electromagnetic weapons, weapon
stabilization, and active defense systems)
▶ Aerospace applications (“more electric aircraft”, drones, micro-satellites)

6. MOST IMPORTANT METRICS FOR ENERGY STORAGE
Units: $/Wh/cycle
or better “cost of
ownership”.
No safety issues for
ultracapacitors or hybrid
devices.
How fast we can use the
energy and how much of
the energy we lose due to
an imperfect system?
How far we can drive?

Practically no difference in
energy density among
ultracapacitor
manufacturers. Lots of hype
around synthetic Graphene,
but no actual applications in
energy storage as yet.

7. C-HEMP CARBON IS THE NATURAL GRAPHENE
Ultracapacitor energy is
proportional to the electrode
effective surface area.
Surface area of C-hemp carbon is
close to theoretical value specified
for Graphene – superior to
commercially available carbons
that are widely used in current
ultracapacitor technology.

8. SUPERIOR CAPACITANCE OF C-HEMP ELECTRODES
(as tested by YUNASKO R&D lab)
High surface area of C-Hemp carbon
translates into superior capacitance/
specific energy of an ultracapacitor.
As a result we can reach the 30%
energy advantage from the same
amount of electrode material.

9. TEST RESULTS FOR C-HEMP ELECTRODES

C-Hemp carbon allows for 30+% more energy and power. Hence, less electrode material or
reduced number of electrodes (also less separator and electrolyte) are needed to get the
target performance. This results in significant cost advantage – see the following slide.

10. FINANCIAL IMPLICATIONS
According to the preliminary cost estimations, the manufacturing cost of C-Hemp carbon is
estimated to be approximately USD10 per kg while the current price for the most used
carbon, YP-50F is USD20…30 per kg (bulk prices may be lower).
The amount of electrodes, separator and electrolyte can also be reduced by ~20% due to the
higher specific capacitance of C-Hemp carbon.
The resulting cost of the best-seller 3000F cell is as follows:
3000F CELL COST, USD: YP-50F C-HEMP
Electrode USD/cell 5.43 2.38
Separator USD/cell 2.86 2.40
Electrolyte USD/cell 3.15 2.64
Casing USD/cell 0.41 0.41
Other materials USD/cell 0.88 0.88
DM cell cost USD/cell 12.73 8.72
We could save 32% or $4 per
3000F cell produced. The current
market leader, Maxwell
Technologies produces over 5M
cells per year. So the annual
benefit from the use of C-Hemp
carbon can reach $20M

11. POTENTIAL BENEFITS
▶ Opportunity to penetrate ultracapacitor market ($2Bn in 2022, CARG >10%) with a high
performing and stable product having ~32% cost advantage.
▶ Access to growing market of carbon for energy storage applications: ultracapacitors and
hybrid lithium ion capacitors with high performance and low cost product. Current market
size for energy storage application is over $300M and growing.
▶ Utilization of hemp stalk (bast fiber and hurd) – low cost and renewable waste from
manufacturing the medical, recreational and technical hemp.
