Embodiment 1

[0044] This embodiment discloses an attached figure 1 The production equipment of the solid-state physical storage battery shown in the figure is composed of a heating furnace 1, a first insulation section 4, a polarization device 2, a second insulation section 5, a cooling forming device 3 and a negative pressure device 6 connected in series, The electrolyte membrane that comes out of the negative pressure device 6 is applied to the making of the forming battery 7 after processing. Because the finally formed electrolyte membrane is a thin film, the outlet of the heating furnace 1 involved in the production equipment, the first insulating section 4, the polarization device 2, the second insulating section 5 and the main body of the cooling forming device 3 are all designed to have A transitional flat channel structure with a certain width.

[0045] For the structure of the electrolyte heating furnace in the production equipment, please refer to the attached figure 2 As show...

Embodiment 2

[0053] This embodiment discloses a preparation process of a solid-state physical storage battery based on Embodiment 1. The process is as follows: the electrolyte raw material 8 is placed in the heating furnace 1, the furnace body 10 is heated by the heating material 18, and the heat is transferred into the heating furnace 1 In the body, the electrolyte raw material 8 in the heating furnace 1 is started to be heated, and the stirrer 13 is also continuously stirring the electrolyte raw material 8, the purpose is to make the electrolyte raw material 8 be heated more evenly, and as the temperature of the electrolyte raw material 8 continues to rise, it is composed of powder particles The state gradually melts into a liquid state, and the temperature signal is transmitted to the temperature controller 14 through the temperature sensor 15 in the heating furnace 1 body. After reaching a predetermined temperature, the temperature controller 14 cuts off the power supply and stops heatin...

Embodiment 3

[0055]This embodiment provides a shaped battery structure, the shaped battery structure is made by processing the polar electrolyte film 41 obtained through the preparation process of Example 2, and the shaped battery structure includes a thin film electrolyte 46, polar electrolyte film 41 Electrolyte film negative terminal 47, polar electrolyte film positive terminal 48, battery positive terminal 49, battery positive terminal dielectric 50, battery negative terminal 51, battery negative terminal dielectric 52, battery positive lead 53, battery negative lead 54, A storage battery made of thin film electrolyte 46 . The solid-state physical battery involved in the present invention is different from the existing storage battery structure in that the middle layer of the thinned electrolyte 46 does not contain an electrolyte diaphragm in the middle.

[0056] The storage battery formed by processing the above-mentioned polarized solid electrolyte film has no electrolyte diaphragm i...

Abstract

The invention relates to an electrolyte membrane, its production equipment and preparation process. The invention utilizes the negative temperature state of the electrolyte, and under the action of applied voltage and heat, it melts into a liquid electrolyte and at the same time makes the polarity of the electrolyte change from disorder to In order to achieve the polarity of the electrolyte, in order to prevent heat loss and voltage removal, after the electrolyte changes from liquid to solid, the electrolyte becomes disordered and non-polar again. In the process of gradually decreasing the temperature, the applied voltage Under continuous action, the electrolyte is gradually cooled down to the normal operating temperature of the battery. During this process, the electrolyte is transformed from a liquid state to a polar solid state, and the polarity of the electrolyte is still maintained.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular, an electrolyte membrane applied to solid-state physical accumulators, its production equipment and preparation process. Background technique [0002] With the continuous progress of modern science and technology, while greatly meeting people's material and spiritual civilization needs, low-carbon, energy-saving, and emission reduction are the best choices for sustainable development. [0003] The preparation of electrolyte membrane (also known as diaphragm) is one of the core technologies of lithium-ion batteries. It plays a role in isolating the positive and negative electrodes in the battery and preventing electrons from passing through, while allowing ions to pass through, thereby completing the charging and discharging process of lithium ions. Fast transmission between positive and negative electrodes. [0004] Batteries produced with existing electrolyte diaphragms have ...
