Description

Water removing device of battery device

Technical Field

The utility model belongs to the technical field of secondary battery device, in particular to a brand-new design of a dewatering device of a battery device, which can achieve the purposes of continuously and rapidly removing the water in the battery device, and having the advantages of uniform dryness in the battery device and uniform quality.

Background

Due to the vigorous development of the 3C product market, various high performance devices applied to various products have been developed in addition to the light, thin, short, and small targets. In order to increase the battery usage time and increase the energy density of the battery, the primary battery that cannot be reused previously cannot meet the requirements of the electronic information products, and most of the batteries currently used in the electronic information products use a rechargeable battery system that can be charged and discharged repeatedly as the main stream. Such as: lithium batteries, fuel cells, solar cells 8230, and the like. However, the conventional lithium ion secondary battery mainly uses a liquid electrolyte as a lithium ion transmission medium, but the volatile property of the liquid electrolyte can cause adverse effects on human bodies and the environment; meanwhile, the flammability of liquid electrolytes is also a great safety concern for battery users. Furthermore, one of the reasons for the unstable performance of the current lithium battery is mainly that the surface activity of the electrode is relatively high (negative electrode) and the voltage is relatively high (positive electrode), so that the interface between the electrode and the electrolyte is unstable under the direct contact between the electrode and the electrolyte, and further, a so-called exothermic reaction is generated to form a passive protective film on the contact interface between the electrode and the electrolyte, and the reactions consume the liquid electrolyte and the lithium ions and generate heat. Once local short circuit occurs, the local temperature rises rapidly, and at the moment, the passive protective film becomes unstable and releases heat; this exothermic reaction is cumulative, and the temperature of the entire battery continues to rise. Once the temperature of the battery is increased to the initial temperature (or trigger temperature) of the thermal runaway reaction (thermal runaway), a thermal runaway phenomenon is caused, which may cause damage to the battery, such as explosion or fire, and cause considerable safety concerns in use (taiwan patent No. I676316). In recent years, solid electrolytes have become another focus of research, having ionic conductivity similar to that of liquid electrolytes, but without the easy evaporation and combustion properties of liquid electrolytes, while the interface with the active material surface is relatively stable (whether chemical or electrochemical).

Taiwan patent publication No. I655304, "manufacture of high capacity solid state battery" discloses a method for manufacturing a thin film solid state battery device using a closed loop process to create multiple stacks to obtain high capacity of more than 0.1mAh, wherein the method comprises a processing step on a thin substrate (0.1 μm to 100 μm), the closed loop process comprising the steps of: performing a plurality of processes to create a single stack by sequentially depositing a plurality of materials taken from deposition sources to form a resulting electrochemical cell on the substrate, the plurality of processes comprising at least one of: depositing a first current collector on the substrate; depositing a first electrode layer capable of undergoing an electrochemical reaction with ions on the current collector; depositing a solid electrolyte material on the first electrode layer; depositing a second electrode layer on the solid electrolyte material; depositing a second current collector on the second electrode layer; moving the substrate, and then forming a second electrochemical cell on the substrate over the resulting stack of electrochemical cells; and repeating the cell stack deposition sequence until a multi-stack cell having a high capacitance equal to or greater than 0.1mAh is formed on the substrate, wherein the substrate further comprises a release material selected from at least one of: fluoropolymer, monomer, oligomer, conductive material, or combination thereof, bifunctional release layer, desiccant, depolymerization layer, thermal release material, polyimide, polydimethylsiloxane (PDMS), semi-organic siloxane, hydrophobic layer, epitaxial release material, amorphous fluoropolymer, radiation release material (2019, 04/01 day). Taiwan patent publication No. I646713, "manufacturing of solid state battery" discloses a method of manufacturing a solid state battery, comprising the steps of: providing a positive electrode material blank sheet; providing a blank sheet of a separator material; laminating the green sheet of positive electrode material and the green sheet of separator material together to form a stack of green sheets; sintering the laminate green sheet stack to form a sintered stack, the sintered stack comprising a positive electrode and a separator; and laminating a negative electrode on the sintered stack (see patent publication data on year 2019, 01). Taiwan patent publication No. I624976, "manufacturing method of solid-state battery", discloses a manufacturing method of a solid-state battery, including the following steps: a. providing a battery unit, wherein the battery unit comprises a positive plate, a solid electrolyte layer and a negative plate which are sequentially stacked, and the positive plate comprises a first current collecting layer and positive material layers respectively combined on two side surfaces of the first current collecting layer; b. positioning the battery unit on a bearing plate in a pressure chamber, wherein the pressure chamber is provided with a fluid medium; and c, providing the medium temperature control of 20 to 200 ℃ and the medium pressure control of 5 to 100000PSI to soften and joint the joint surfaces of the positive plate, the solid electrolyte layer and the negative plate (the patent publication data of 21/05/2018).

In the conventional battery package structure, no matter the primary battery system or the secondary battery system, most of the conventional battery packages are formed by hard metal cases (including conventional cylindrical and square cases), for example: the 18650 type lithium battery (cylindrical lithium battery) widely used in notebook computers or 383562 type lithium battery (square lithium battery) widely used in portable communication devices at present all use a hard metal case as a packaging material, and such a packaging method can not only prevent a battery core from being damaged by external stress, but also reduce the influence of external factors (such as moisture, oxygen, 8230and the like) on a chemical system in the battery. Therefore, although the secondary lithium battery can provide better electrical performance and service life for the terminal electronic products, most of the electronic products are greatly limited in circuit design due to its fixed size design and hard housing material. Therefore, a secondary battery device has developed to replace the conventional hard metal casing with a soft metal casing (such as aluminum foil) structure, so as to reduce the difficulty of applying the secondary battery system to electronic products. In particular, the solid-state battery device stacked in a sheet form has an advantage of greatly reducing the volume of the battery device as compared with a cylindrical battery device. As such, such batteries may be used in a variety of applications, such as portable electronic devices (cell phones, personal digital assistants, music players, video recorders, and the like), power tools, power sources for military use (communications, lighting, imaging, and the like), power sources for aerospace applications (power for satellites), and power sources for vehicular applications (hybrid electric vehicles, plug-in hybrid electric vehicles, and all-electric vehicles).

However, the above-mentioned stacked solid-state battery device packaged with a soft metal (e.g., aluminum foil) has to have a water content of less than 200ppm due to the internal sheet-like battery device, which may cause defects such as damage to the battery device and reduction in the life of the battery device after packaging. In the prior art, when the battery device is packaged by soft metal, one side of the battery device is left unsealed, and then the battery device is placed into an oven to be baked and dried. Furthermore, because the interior of the battery device is of a stacked structure, the drying is more difficult as the battery device is stacked in multiple layers, the battery device is more likely to be deformed and damaged except for a long time, and the drying degree in the interior is uneven, so that the requirement of consistent quality cannot be met. Furthermore, the battery device is placed inside the oven for drying in the prior art, the moisture inside the battery device can only be slowly evaporated by the temperature due to the release of the moisture inside the battery device without pressure, and the evaporated moisture is not easily discharged from the inside, so the drying process takes a long time, and the moisture content inside the battery device is not uniform due to uneven heating temperature in the prior art, which results in poor quality. The lack of the conventional drying and dewatering technology for battery devices is a difficult problem to overcome in the industry.
