New process for synthesis of inorganic
materials
CONTEXT
Synthesis of inorganic compounds usually imply process at high
temperature (ceramic, sintering) or solvothermal processes (precipitation
in liquid medium at room temperature).
Ceramic processes allow to obtain polydispersed powders and are costly
due to high temperature. On the contrary solvothermal process gives a
better control on particle size if the steps of nuclear growth are well
controlled. Yet, existence of soluble precursors can limit the range of
inorganic compound available and by-products are often obtain. A
supplementary step of purification is needed and these by- products must
be retreated.
TECHNICAL DESCRIPTION
The invention described a new process of inorganic compound’s
synthesis in ionic liquid and at low temperature.

Method for production of an anode for
lithium ion battery
CONTEXT
In LIB development during past years, efforts were mainly done in
cathode materials. However, in recent years, research were also made to
replace the traditional graphite anode by other materials allowing better
electrochemical performances.
TECHNICAL DESCRIPTION
The invention relates to a method for production of an anode for a lithium
ion battery, said annode comprising a current collector made from a
transition metal in a sponge form and an active material made from a
binary phosphide. The method involves subjecting a transition metal
sponge to the effect of phosphorous vapors at a temperature of 300-600
degree Celsius. The phosphorous is present in a stoichiometric amount
with respect to the transition metal. An active material is made from a
binary phosphide of the metal. The reaction between the metal sponge
and the phosphorous is implemented during a time of 6-120 hours.
BENEFITS
The method allows an anode to be obtained which has a continuity
solution between active material and a current collector in order to
optimize the active material/current collector interface with better
electronic conductivity so providing anode with improved cycling behavior.
The method therefore eliminates the need to mix carbon with the active
material to improve its electroconductivity. The method allows the
synthesis of the active material and the production of the anode to be
carried out in a single step so simplifying the production of the battery.
The anode formed and its compounds are non-toxic, and are stable to the
air and the water. The use of the sponge permits rapid reaction between
the transition metal and phosphorus, and leads to a uniform deposit of the
metal phosphide layer.
INDUSTRIAL APPLICATIONS
This invention could be used to develop the anode of rechargeable
lithium-ion batteries. The anode and its components are not toxic and are
stable in presence of water or air.

Ionic conducting gels
CONTEXT
The sol-gel process is well known in the prior art, simple to implement, takes
place under mild conditions and facilitates the shaping of materials.
In a standard fashion, the sol-gel process consists of a hydrolysis and
condensation process which, starting with a molecular precursor (true solution)
leads to the formation of a colloidal solution (or sol) then, by connection of the
colloidal particles, to the formation of a continuous solid skeleton named a gel.
The non-hydrolytic sol-gel process is a particular case of a sol-gel process, taking
place in the absence of water. Another notable particular case consists of a solgel process for obtaining silica gels by using formic acid (formation of water in
situ) (Sharp, 1994; Dai, 2000).
Ionic Liquids have remarkable properties such as zero volatility, a high ionic
conductivity as well as catalytic properties. They are currently used in numerous
fields, in particular as electrolytes.
Inventors have decided to combine properties of silica gels and ionic liquids.
TECHNICAL DESCRIPTION
The invention describes a one-step process consisting in preparing a new ionic
conductive gel in solid form known as ionogel. The method consist in a step of
mixing an ionic liquid with at least one molecular precursor containing at least
one hydrolysable group, if necessary in the presence of an acid such as
carboxylic acid. The mixture is subsequently left to stand for one or more days
until a gel is formed by polycondensation of the molecular precursor(s). The gel
contains the aforementioned ionic liquid and can be set in particular in
transparent monolithic solid form.

Status of Patent
This invention describes compound that could be used as additives in LIB
electrolyte. These compounds fill the gap between battery and supercapacitor.
BENEFITS
The process allows to avoid the following drawbacks:
Security due to a lack of liquid electrolyte and explosion or fire.
Multistep fabrication including hot lamination, Bellcore technology (gel
electrolyte) or sintering for ceramic electrolyte.
A low quantity of active material in the electrode.
The patented process is fully compatible with state of the art electrode
preparation process with no need of high temperature or additional chemical
treatment.
As all solid electrolyte is obtained, there is no problem of security as fire,
explosion...
Thick electrode can be obtained without a diminution of active material.
The presence of active material is increased. For example for LiCoO2 electrode
or LiNi1/3Mn1/3Co1/3O2 electrode with the patented process we can obtain a 8590 wt% of active material compared to 40-45 wt% usually observed.
INDUSTRIAL APPLICATIONS
This process could be used obviously in lithium accumulator. However it is not
limited to this application.
For example we can underline other applications such as:
Micro batteries: as there is no treatment needed more than 100°C, the
process could be implemented directely on a printed circuit.

Process to reduce capacity loss during first
cycle
CONTEXT
During the first cycling of a lithium-ion batterie, a solid electrolyte interface
(SEI) is formed on the negative anode (graphite is the most used anode
material).
The SEI formation protect the anode but one drawback is that lithium ion are
used to form this SEI resulting in a loss of capacity for the battery.
TECHNICAL DESCRIPTION
The invention relates to a composite electrode which includes a mixture of
active material particles (AM) and particles constituted with a material
generating an electronic co The invention proposes to use sacrificial salt that
during the first cycle will be oxidized producing by this way alkali ion such as

Solid polymeric electrolyte for LIB
CONTEXT
Electrolyte is an important component of lithium-ion batteries. For a large part,
electrolyte is made of a dissolved lithium salts in a mix of organic solvents.
However, gel polymers are also used as electrolyte due to their facility to adopt
different forms.
Gel polymers are generally made of linear polymers (such as PEO or
PVDF/hexafluoropropylene copolymer), lithium salt and organic solvants. Key
criteria is the ionic conductivity at RT which is close to that of liquid electrolytes.
It also exists all solid state LIB in which there is no organic solvent in the polymer.
Main advantage is that there is no evaporation of solvents.
TECHNICAL DESCRIPTION
The present invention is a new solid polymeric electrolyte which comprises a
polymeric matrix in the form of a semi-interpenetrating polymer network
consisting of a linear elastomer, ie NBR (8.8 14.5 parts by weight) and a crosslinked ionic copolymer (35.0-58.1 parts by weight). This matrix includes a lithium
salt solution (12.4 parts by weight) in an ionic liquid (15.0-43.8 parts by weight).
Thin films can be made.

Iron-doped V2O5 thin layers
CONTEXT
In order to be able to feed micro-electronics circuits for long periods, it is
necessary to increase the density of energy of the microbatteries and
consequently their capacity.
Many studies are therefore currently carried out on thin layer positive electrode
materials.
Vanadium(V) oxide (V2O5), and more generally oxides of transition metals having
a lamellar structure, arouse intensive research works, since they are more
promising than the sulphides because of their greater chemical stability, higher
potentials as compared to the Li/Li+ redox cell and larger discharge capacities.
There is still a need for thin layers positive electrodes for use in microbatteries
presenting an improved behaviour in cycling.
TECHNICAL DESCRIPTION
The invention relates to an iron-doped vanadium oxide (FeyV2O5), the process of
preparation thereof and to thin layers of positive electrode comprising irondoped vanadium oxide having a strong capacity and potentially usable in allsolid-state lithium microbatteries. The invention also relates to the preparation
process of said thin layers by cathode pulverization method.
In the present invention, the known cathode pulverization method has been
improved and comprises the step of carrying out a simultaneous pulverization
starting from two different targets in one pulverisation chamber ( a first
Vanadium-containing-target (the V-target) and a second Iron-containing target
(the Fe-target).
INDUSTRIAL APPLICATIONS
This invention could be used to develop all solid state lithium microbatteries.
This invention opens up the possibility to improve behavior in cycling as
compared to vanadium oxide

Method for the electrolytic production of selfsupporting conductive nanocomposite elements
CONTEXT
In the field of energy storage using batteries, the properties of the electrodes,
and especially of the current collectors that the electrodes include, are an
important element as regards the overall performance of the batteries. In order
for a material to be able to be used as a collector, it is desirable for it to have a
high electronic conductivity, good electrochemical stability and a large area of
contact with the active material. Nanomaterials have a high area/volume ratio
thereby increasing the reaction rates, by reducing the diffusional limitations, and
the use of nanomaterials for production of current collectors is under
development.
TECHNICAL DESCRIPTION
The invention relates to a self-supporting composite element and to a method of
producing such element. The composite element comprises a substrate of
electronic conductive material which is covered with metal nanowires that are
essentially oriented along a plane that is perpendicular to the substrate.
The element is produced in a cell comprising a cathode which is formed by the
substrate to be covered, one or more anodes and an electrolyte which is formed
by a solution of a precursor of the metal material and optionally containing a
conductive ionic salt, a flat porous membrane which is placed between the
cathode and each of the anodes and a spacer element between each membrane
and the anode adjacent thereto, the different constituent parts of the cell being
maintained in contact
INDUSTRIAL APPLICATIONS.
The current collectors and the electrodes according to the invention may be
used in many electrochemical devices, such as lithium-ion rechargeable
batteries, lithium/polymer rechargeable batteries, non-rechargeable generators,
supercapacitors and electrochromic devices

Welding process for Al/Cu electrodes
CONTEXT
When realizing battery pack, it is important to have mechanical contacts
between current collectors. Welding of thin copper and aluminum electrode isn’t
possible due to the large difference between their respective melting point
(around 600°C).
TECHNICAL DESCRIPTION
The invention relates to a specific welding process (called MIG CMT) allowing the
welding between two thin (less than 1 mm) plates of copper and aluminum.
In the above figure, we can see the welding with (from left to right), aluminum
electrode, welding zone and copper electrode
Development stage
Over 30 tests were done with good reproductibility without specific optimization
of the process. Analysis demonstrates the welding between Al/Cu.
In addition, preliminary tests demonstrate a good resistance to vibrations and a
normal use of the welded cells.
Future developments are ongoing for welding the electrode in end to end
relation.
