New industrial methods for the preparation of high-quality graphene in large amounts

We are not into making the finest square centimeter of graphene. Neither we are into making the oxidized stuff (although we know how to prepare it). We make large amounts of high-quality graphene (no oxygen) through our own fabrication method.

 

Nanofluids are HOT

Heat Transfer Fluids (HTFs) have shown they are great at transferring heat at low temperatures. We want to understand why and we want them working at high temperatures for boosting thermal solar energy.

 

SupercapBatteries. Hybrid Supercapacitors made of hybrid electrodes for hybrid energy storage.

We work on batteries (great energy, poor power), we work on supercapacitors (great power, poor energy). Now we also work on hybridizing them to get extra energy density while keeping high power.

New flow cell concepts for fast energy storage.

The idea is storing fluids with high energy density in large tanks externally to the electrochemical reactor that we have always called battery. This type of liquid storage is bound to obliterate the word “intermittent“ out of renewable energies and even end up fueling our not-so-far-ahead future electric cars. Our novel materials provide fast charge-discharge processes. Patent Pending
