Presentation at IMIEC 2018 dedicated to extending battery performance.

1. EXTENDING THE BATTERY PERFORMANCE LIMITS
THROUGH THE COMBINATION OF TECHNOLOGIES
August 2018

2. NEED FOR ENERGY STORAGE AND HARVESTING
2
No electric vehicles
possible without storage
No CO2 emission
reduction possible
without hybridizing ICE
No renewables possible
without storage
No smart grids possible
without storage

3. MOST IMPORTANT METRICS FOR ENERGY STORAGE
Units: $/Wh/cycle
or better “cost of
ownership”.
How fast we could use the
energy and how much of the
energy we lose due to an
imperfect system?
How far we could drive?

4. CHALLENGES FOR BATTERIES
▶ Low charge / discharge rate (not quick enough for frequency
regulation in grids, slow charge of EV battery)
▶ Safety concerns (fire hazard)
▶ Short lifetime (expensive to change)
▶ Low and high temperatures intolerance
▶ Low efficiency (heat generation requires expensive thermal
management systems)

BATTERY vs ULTRACAPACITOR
HOW TO CREATE A MÉLANGE OF LARGE ENERGY AND HIGH POWER?

6. Effect of low inner resistance of Yunasko ultracapacitor module (A)
as compared with the best competing devices (B):
1 – current flowing through battery; 2 – current flowing through ultracapacitor;
3 – total current
Yunasko UC effectively unloads the battery and enhances total current
(parallel connection with a battery)

HYBRIDIZATION: TYPES OF CAPACITOR SYSTEMS

8. RESULT: energy storage system with battery-type charge-
discharge curve and energy density up to 40 Wh/kg
(also confirmed by tests in ITS, Davis, USA and VW Group,
Germany)
PARALLEL HYBRID SOLUTION
LITHIUM-ION CAPACITORS
OUR APPROACH: electrode level hybridization - both
positive and negative electrodes comprise Li-ion and
activated carbon components with thoroughly matched
potential ranges: “parallel hybrid” //LIC, patent pending

TECHNOLOGY COMPARISON
We can safely charge
energy of lead-acid
battery within 2 minutes
and discharge up to
150C* rate (~20s) with
efficiency >80%
* NOTE: C-Rate is a measure of the rate (time or current) at which a battery is charged or discharged relative to the capacity
of the battery. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. 11
