Graphergia Lexicon

Discover GRAPHERGIA’s innovative technologies to power future energy with graphene:

TENG

Tribo-electric nano-generators (TENGs) are miniature devices able to harvest mechanical energy (friction at the nanoscale) and convert it to electricity.

PE CVD

Plasma-Enhanced Chemical Vapor Deposition process. It will be used in GRAPHERGIA to deposit the energy harvesting layer.

LIB ELECTRODES

Lithium-ion Battery electrode.

MEMS

Micro-ElectroMechanical System is a miniature machine that has both mechanical and electronic components.

R2R

Roll-to-Roll manufacturing involves the processing of a rolled substrate through a roller-based processing line, with the final material being again re-rolled. Proper for processing textiles and flexible substrates.

MICRO-FLEXIBLE SC

A planar type SuperCapacitor with interdigitated electrodes fabricated onto a flexible substrate.

GRM

Graphene-Related Materials (e.g. 3D porous graphene, graphene hybrids, etc.).

IL

Ionic Liquids (typically used as electrolytes in electrochemical energy storage devices) are liquids that are largely made of ions.

CRM

Critical Raw Materials (raw materials that are economically and strategically important for the European economy, but have a high-risk associated with their supply, and for which there are no easy substitutes).

AC SIGNAL

An Alternating Current Signal is the current that periodically changes direction.

DC VOLTAGE

A Direct Current Voltage is the voltage that does not change polarity.

2D MATERIALS

In materials science, 2-Dimensional materials are single- or few-layer crystalline solids.

SI NPS

Silicon NanoParticles.

SIOX

Silicon sub-Oxide.

LI+

Lithium cation/ion.

LEST METHOD

Laser-assisted Explosive Synthesis and Transfer. A patented method used in GRAPHERGIA to prepare and deposit graphene onto any type of substrate.

CFP MATERIAL

Carbon Fiber Product.

CFRP

Carbon-Fiber-Reinforced Polymers are materials containing a reinforcing component, the carbon fiber, which provides their strength.

GCD

Galvanostatic Charge-Discharge involves the application of constant positive and negative currents to charge and discharge a material.

IOT

Internet of Things refers to the collective network of interrelated devices and the technology that facilitates communication between the devices and the cloud.
