AMC: Maximum Power Density, Ultra-Fast Charge, Long Life
Novel Amorphous Metallic Carbon (AMC) with unique fractal structure discovered for superior batteries. Fast-charge, longevity, capacity — pick two: not anymore! EV charging @ 20 mins, 10+ years lifespan. Power grids storing renewable energy @ 100% efficiently. AMC — a sustainable future!
The problem
Battery problem #1 — super long charge rate of more than 1 hour
Battery problem #2 — durability less than 500 charging cycles
Battery problem #3 — energy density below 300 Wh/kg
Most devices take too long to charge, and they are less efficient while charging («downtime»)
Ultra-fast charge radically reduces this downtime, but often at the expense of number of charges possible.
Shortened cycle life means more dead batteries contribute to e-waste, faster. Also, it means much higher costs given they need to be thrown away faster

Amorphous Metallic Carbon (AMC) – novel unique carbon phase
VS
Amorphous structure enables more li-ion to be stored, faster
• Porous structure
• No Li plating
• No dendrite growth
• Compatibility with commonly used materials and equipment
Graphite
Layered structure
for li-ion insertion
The Solution
-
#1 — charge rate up to 10-20 min.
-
#2 — durability thousands of cycles, no degradation
-
#3 — energy density up to 1000 Wh/kg
Saved money,
saved environment!
Amorphous Metallic Materials enables ultra-fast charge with long cycle life and high energy density
As an anode material, AMC
is a superior alternative
to graphite.
Carbon-based anodes have no alternative for all types of modern and future type of batteries.
Li-ion, Li-pol, Sodium and other batteries has shown best durability and charge rate with AMC.
Superior batteries with scaled AMC anode. How do we know?
Experimental investigations of batteries made from scaled AMC, produced by Dr. Goikhman @ Koenigssystems, Germany (KS). Tests performed by the world-famous R&D center of El-Cell GmbH and others
AMC — the novel candidate for the anode in long-lifespan, fast-charge, high-capacity batteries:
+ Specific capacity >500 mAh/g (>300 Wh/kg)
+ Fast charge rate ability
+ AMC material demonstrate potential to improve capacity up to 1500 mAh/g with amorphous Si (900 Wh/kg)
+ high coulomb efficiency
Cycle stability of the AMC based Li-ion full cell battery
AMC prototype (nC) full-cell battery was assembled and tested for fast charge (3C) and long cycle life up to 5000 cycles of fast charge.
-
Over 5000 cycles: still alive and kicking.
-
Control cycles don’t demonstrate any degradation.
-
At a high rate, only increased resistance affects the obtained capacity.
AMC-carbon. Scaling is possible. How do we know?
Industry Challenge: Volume production of AMC at industrial scale remained unsolved before 2022, when the team of Dr. A. Goikhman discovered the Arc Discharge process of amorphous-like carbon in his company Koenigssystems, Germany (KS).
DE Patent applied pending since July 2023
-
Prototype Lab rector build. Current synthesis rate ~ few grams per day
-
Energy consumption <10 Wh per 1 g (low OPEX)
-
Reliable and simple process - stored energy is used directly for sputtering.
-
Multiple-source reactor is now in operation.
AMC: Maximum Power Density, Ultra-Fast Charge, Long Life
The only reason why the AMC material has not yet taken over the market of anode materials is the scaling of the production process, which can be overcome
by our project
Let’s build together!
