Battery manufacturing The quality of the electrode pole piece affects the battery performance a lot. If the pole piece is made poorly, the battery cannot reach the required capacity. The pole piece production can be roughly divided into powdery active material pretreatment, slurry preparation, and pole. Tablet coating, rolling and slitting. In the pretreatment of powdery active materials, the main adjustments are particle size distribution or heating to remove impurities, change the structure, etc. After that, the powdery active material, binder and solvent are mixed into a paste. After the proper viscosity is adjusted, the pole piece is coated to make the active material adhere to the substrate. Among them, the adhesive uses two molecules with stability, such as polytetrafluoroethylene (PTFE), polydifluoroethylene compound ( PVDF), copolymer of difluoroethylene and hexafluoroisopropanol (PVDF-HFP), acrylonitrile polymer (PAN), and the general conductive substrates are mostly used as active material supports and current collectors, and existing conductive substrates The material can be divided into two types: metal foil and metal mesh. The thickness coating, flatness, coating speed and reliability are considered for pole piece coating, and they can be rolled after proper drying procedures. The purpose of compression is to obtain higher density pole pieces. In terms of electrolytes, the main function of the electrolyte is to transfer charge between the positive and negative electrodes. Therefore, the electrolyte must have high conductivity to increase ions. And reduce the internal resistance when the battery is discharged.

Among them, the electrolyte is mostly lithium salt, such as LiPH6, LiClCU, LiAsF6, LiBF4, LiCFsSCh Or LiN (CF3S〇2) 2, etc., can fully dissociate in the solvent to form anions and cations and have ionic conductivity. Generally, conductive ions, such as lithium ions, have the function of conducting charge and also participate in the electrochemical reaction. In addition, the main body of the lithium ion electrolyte is a non-aqueous organic solvent, which is based on the fact that lithium metal easily reacts violently with water, causing battery safety problems. Generally organic solvents such as Ethylene Carbonate (EC), Propylene Carbonate (PC), Dimethyl Carbonate (DMC) 'Diethyl Carbonate (DEC), Ethyl Methyl Carbonate (EMC) and other components. Electrolyte considerations are mainly based on high conductivity, and at the same time, low viscosity is conducive to the movement of ions, while high boiling point and low freezing point can make lithium batteries have a wide temperature range, and safety considerations' electrolyte must also With low volatility, high flash point and high stability. Under these multiple considerations, a single organic solvent cannot meet the above requirements, so generally two or more solvents are used in lithium batteries to meet the needs of battery operation. Another newly-developed lithium battery is a lithium polymer battery, which has a solid polymer electrolyte without leakage, explosion, and toxicity issues, and is in line with environmental protection and safety advantages. In addition, solid electrolytes can be used as separators, which is beneficial for production. Thinner battery. However, since the conductivity of solid electrolyte cannot be comparable to that of liquid electrolyte, its suitable composition is still under development.

In this process, when the electrode electrode rolls up to two :: activated lithium ions and lithium metal redox, the volume shrinkage and expansion changes between the susceptible susceptible to the negative: the gas generated during the material process, or the electrolyte Charging and discharging of heated steam will also squeeze the pole pieces and cause deformation. Such deformation will cause the battery to have poor airbag integrity and even wrinkles, which may lead to a decrease in electrical capacity and shorten battery life. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs of the China Electric Power Bureau in order to reduce the damage to the flat structure of the battery stack 4 caused by these pressures, and the sound coil structure causes electrical deterioration. These volume stresses, or guide or dissipate these volumes, should not affect the flat structure between the electrode pads in the surroundings. The most commonly used is known: tied to the completed rolls, fixed with tape, so that the rolls and the pads are fixed. It is not easy to loosen in time, so that the generated gas or air bubbles will move elsewhere to reduce the damage to the pole piece. The conventional method of fixing with adhesive tape is still insufficient.

Description of the invention (Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs to improve the battery life, therefore, any conceivable changes made within this porous liner are used within the scope of this invention. In addition, in order to protect the roll and avoid short circuit, a layer of insulation film is added between the more structure and the roll of the present invention, such as non-woven fabric or breathable plastic film. This insulation film can be heat-fused or glued. Medium is better One way is to make the fusion method 'make the separator adhere to the surface of the porous lining element of the present invention facing the pole roll. Such a device can be used as a buffer 1 for the stress caused by the volume change between the electrode pole roll pole layers. The purpose of protecting the electrode sheet from being squeezed and damaged between layers and improving the safety of the battery is achieved. The porous lining element of the present invention has a very small proportion of the internal volume of the battery, which will not waste space and reduce the capacity. When the electrode is charged and discharged, In the process, in addition to the natural expansion and contraction of the electrode material that can be pressed and fixed, if the organic solvent of the electrolyte is vaporized or unexpected due to temperature effects The gas generated by the chemical side reaction, the pores of the porous lining element can also provide a way to release the gas. The present invention provides a porous lining element with improved battery life, which has low cost, small size, The advantages of high air permeability, high heat dissipation, and mechanical strength. 'The addition of this component can indeed improve the degree of deformation between the layers of the pole pieces to maintain the structural integrity of the stack between the pole pieces of the battery, and increase the battery life.
