Lighter, safer and more efficient Li-ion batteries
What we have patented are new ceramic electrodes
distinguished by being much safer,
and they allow us to work on a wider temperature range.
These electrodes were manufactured using a technology
developed in our research group, the thermoplastic extrusion molding,
where we have an extensive experience.
Extrusion is like a churros-making machine.
Basically, a plastic material goes through a nozzle
of a certain size,
and that allows you to make layers, tubes or any geometry you want,
as long as it is two-dimensional.
The advantage of this technique is it lets you produce some electrodes,
either with planar or tubular morphology,
that can be applied on any type of battery
with these characteristics.
This technique can be used in the entire field of energy storage.
For example, in the development of renewable energy,
which is very important; for instance, the photovoltaic one,
windmills and electric cars,
where there is a very important security problem.
The advantages of this technology are:
it doesn't use any solvent during the process
and, secondly, this material is hard.
If you compare it to conventional electrodes,
that are friable and they remain on your hands,
you will see this is hard. It can't be cut.
So this contributes to the battery strength.
