Definitions

  • the reversible insertion of lithium ions in the electrode material causes a volume variation of said material, namely an increase in volume during insertion, and a decrease in volume during disinsertion.
  • This variation in volume causes harmful effects for the battery, such as the cracking of the passivation which forms on the surface of the electrode during the first cycling, said cracking resulting in a loss of capacity and / or electronic conductivity.
  • SEM scanning electron microscopy
  • the invention relates to:
  • the electronic conductive carbon is chosen from: carbon blacks, acetylene blacks, carbon fibers such as those called VGCF ("vapor grown carbon fiber", marketed by Showa-Denko), carbon nanotubes and graphenes.
  • binder in the anode material and the binder in the protective material are independently selected from: a polyvinylidene fluoride (PVDF), a fluoride copolymer of vinylidene and hexafluoropropene (PVFD-HFP), a polyimide, a natural or synthetic rubber, a carboxymethyl cellulose (CMC), an alginate in acid form or in the form of a salt, and a mixture thereof.
  • PVDF polyvinylidene fluoride
  • PVFD-HFP fluoride copolymer of vinylidene and hexafluoropropene
  • CMC carboxymethyl cellulose
  • Process for producing an anode comprising the following steps: a) preparing a composition intended to form an anode material film by mixing an active ingredient or an active substance precursor, a first binder and a first electronic conduction agent in a first solvent; b) preparing a composition for forming a protective film by mixing a second electronic conduction agent with a second binder in a second solvent;
  • FIG. 1 illustrates an anode according to the invention.
  • the binder of the anode material 4A and the binder of the protective film 4B are identical.
  • the anode active material precursor introduced into the composition for forming the anode material film 7 is a powder of silicon, silicon oxide or an Si-Li alloy.
  • the composition for forming the anode material film may comprise about 5 to 20 parts by weight of a solvent, and about 80 to 95 parts by weight of a mixture consisting of: 80-95% by weight of active ingredient precursor, 2-20% by weight of binder, and 1-10% by weight of electronically conductive carbon.
  • the solvent used depends on the nature of the binder 4B.
  • the solvent used is N-methylpyrrolidone (NMP) or cyclopentanone when the binder is PVDF or a polyimide.
  • a composition intended to form one of the films of the anode is deposited either on the current collector or on a film already deposited, and then it is subjected to a heat treatment to remove the solvent.
  • the heat treatment is carried out under vacuum.
  • the temperature of the heat treatment depends on the boiling temperature of the binder used. It may for example be around 120 ° C when the binder is PVDF or CMC, or around 150 ° C when the binder is a polyimine.
  • An anode according to the invention is useful in a lithium ion battery in which the cathode is constituted by an electrode material carried by a current collector and the electrolyte consists of a solution of a lithium salt. in a solvent, said solvent being a liquid solvent, a polymer solvent or a gel solvent.
  • the solvent may be chosen from polar organic aprotic liquids, ionic liquids, or mixtures thereof.
  • polar aprotic liquid mention may be made of linear ethers and cyclic ethers, esters, nitriles, nitro derivatives, amides, sulfones, sulfolanes, alkylsulfamides and partially hydrogenated hydrocarbons.
  • Particularly preferred solvents are diethyl ether, dimethoxyethane, glyme, tetrahydrofuran, dioxane, dimethyltetrahydrofuran, methyl or ethyl formate, propylene carbonate or ethylene carbonate, alkyl carbonates (especially dimethyl carbonate, diethyl carbonate and methylpropyl carbonate), butyrolactones, acetonitrile, benzonitrile, nitromethane, nitrobenzene, dimethylformamide, diethylformamide, vinyl carbonate, dimethylsulfone, tetramethylene sulfone, tetramethylene sulfone and tetraalkylsulfonamides having 5 to 10 carbon atoms.
  • the present invention is illustrated by the following examples, to which it is however not limited.
  • a composition for forming the protective film was prepared.
  • the constituents of the protective film are given in Table 2 below.
  • the composition for forming the protective film contains water as a solvent. In the composition for forming the protective film, the water is about 75.42 g.
  • a composition for forming the protective film was prepared.
  • the constituents of the protective film are given in Table 4 below.
  • Each electrochemical cell was subjected to a series of charge / discharge cycles with a C / 24 regime (discharge in 24 hours) in galvanostatic mode between 10 mV and 2.5 V at 25 ° C.
  • the comparison of the cells 1200B and 1200D shows that the presence of the protective film significantly increases the reversible capacity, which is an index of a decrease in the volume expansion during the insertion of lithium ions in the anode material, without decreasing coulombic efficiency 1 and coulombic efficiency 2.
