Explosion-proof power battery adopting injection molding method to fix electrode, and manufacturing method thereof

Abstract

The present invention relates to an explosion-proof power battery adopting an injection molding method to fix an electrode, and a manufacturing method thereof. The explosion-proof power battery comprises a housing, a bottom cover, battery monomers, heat dissipation plates, an upper cover, and an electrode lead-out mechanism. The heat dissipation plate is arranged between the adjacent two battery monomers. A plurality of the battery monomers and the heat dissipation plates are assembled into a battery main body, and the battery main body is arranged inside the housing. The bottom cover is arranged on the bottom end of the housing. The electrode lead-out mechanism connected to the battery main body is arranged on the upper surface of the housing. One side of the housing is provided with an explosion-proof interface. The electrode lead-out mechanism comprises a fixation upper block, a fixation lower block, and electrode lead-out terminals, wherein the fixation upper block and the fixation lower block are fixed on both sides of the upper cover through hot melting, the electrode lead-out terminals are sleeved with insulating sleeves, and are inserted and connected in lead-out holes on the fixation lower block, the upper cover and the fixation upper block, and the electrode lead-out terminals, the fixation lower block, the upper cover and the fixation upper block are fixed into the integration through hot melting.

Description

technical field [0001] The invention relates to the field of hybrid power batteries, in particular to an explosion-proof power battery using an injection molding method to fix electrodes and a manufacturing method thereof. Background technique [0002] As a new type of energy, hybrid batteries have extremely far-reaching prospects in application. However, there are also some problems in its production and use. Take power batteries with larger capacity as an example. Some models such as 40Ah, 50Ah, and 60Ah are commonly used products. There are extremely contradictory conflicts in product design. Since the large capacity is mostly used in electric vehicles, electric bicycles and some large electric tools, the voltage is generally around 500V-600V (car batteries), so the battery must be given priority. security and stability. [0003] As we all know, the battery itself is an independent power supply with positive and negative electrodes. The charge and discharge current of a...

AI Technical Summary

Problems solved by technology

Batteries with non-metal shells are prone to shell deformation, short circuit, etc. in this working environment, and it is easy to cause fire in severe cases (the shell itself is flammable)

The use environment will also affect the heat dissipation of the battery. As a new energy source, hybrid batteries are widely applicable. When using batteries, there will be many environmental factors, such as airtight, high temperature, freezing and other conditions, which will affect the "quality" of the battery itself. The requirements will be very strict, and the adaptability of non-metal shells to harsh environments is relatively weak.

②, the problem of vibration resistance, because the electrodes are led out in the form of screws, so there will be certain restrictions on the applicable conditions, such as the car will inevitably vibrate when driving, so the use of screws as the connection method will cause loosening, serious adverse consequences
