Problems solved by technology

[0005] 1. The thickness of a single thermal battery is between 1.5-3.5mm, which cannot solve the problem of miniaturization of thermal batteries;
[0006] 2. The utilization rate of the electrode material of the traditional single thermal battery is low, and the waste of the electrode material is serious;
[0007] 3. In order to prevent the conduction of the single hot battery, the electrolyte diaphragm layer is thicker, which leads to a longer activation time of the hot battery;
[0008] 4. The flakes obtained by the powder pressing process

Embodiment Construction

[0028] Such as figure 1 As shown, a method for preparing a thin-film monolithic thermal battery with a central hole includes a mold body. First, a collector sheet 1 with a central hole and an inert choke ring 2 are sequentially placed in the mold body from bottom to top. The negative electrode film and the electrolyte diaphragm are placed in the choke ring 2 sequentially, and finally the positive electrode film is placed on the upper end of the inert choke ring and moved to a hydraulic press for compression molding. (Placement order needs to be modified)

[0029] The current collector sheet 1, the negative electrode film sheet 3, the electrolyte diaphragm sheet 4 and the positive electrode film sheet 5 are all mesoporous sheet structures.

[0030] The material of the current collector sheet 1 is nickel sheet, stainless steel sheet, copper foil or graphite paper and the like.

[0031] The inert choke ring 2 is made of asbestos fiber and magnesium oxide, or is made by punching...

Abstract

The invention relates to a preparation method of a thin film single thermal battery with a central hole. The thin film single thermal battery comprises a die body. The preparation method comprises the steps of firstly, sequentially placing a collector plate with a central hole and an inertia current blocking ring in the die body from bottom to top; secondly, sequentially placing a negative electrode thin film sheet and an electrolyte separator sheet in the current blocking ring; and finally, placing a positive electrode thin film sheet at an upper end of the inertia current blocking ring, and moving the inertia current blocking ring to a hydraulic machine for pressing and formation. The preparation process of the single thermal battery is simplified, the prepared single battery has the advantages of small size, fast activation, high-overload impact resistance, stable electrical property and the like, the production efficiency can be effectively improved, the battery manufacturing cost is reduced, and the single battery has relatively good application prospect.

Description

technical field [0001] The invention relates to a thin-film single thermal battery with a central hole and a preparation method thereof, belonging to the field of thermal battery manufacturing. Background technique [0002] Thermal battery is a heat-activated reserve battery that uses its own heating system to heat and melt the non-ion-conducting solid salt to become an ion conductor and enter the working state. It is composed of electric stack, activation mechanism, ignition strip, insulation material, battery shell, etc. Among them, the electric stack is its core part, and its performance directly determines the performance of the thermal battery. The electric stack is composed of multiple monomers Composition, the monomer is composed of positive electrode, negative electrode, electrolyte, current collector and heating sheet. The thermal battery has the advantages of short activation time, large output power, high specific energy, wide temperature range and long storage ti...
