Problems solved by technology

Because the existing tab itself is relatively thin, it cannot withstand the passage of a large current in an instant, causing the existing tab to be melted, resulting in damage to the battery
In order to solve the above-mentioned problem of thin tabs, a conventional tab appeared subsequently. The conventional tab increases the thickness and width of the tab on the basis of the original tab, making the battery thick and bulky. extremely inconvenient

Embodiment Construction

[0026] Please refer to Figures 1 to 5 As shown, a high-rate discharge battery provided by the present invention is described below in conjunction with the embodiments, which includes positive and negative electrode sheets 1, 2 and a diaphragm 3 placed between the positive and negative electrode sheets 1, 2, between the positive and negative electrode sheets 1 , 2 are respectively connected in parallel with at least two tabs 4, and the tabs 4 and 4 can be equidistantly arranged on the positive and negative pole pieces 1, 2 or two pole pieces arranged on the positive and negative pole pieces 1, 2. terminal; it is beneficial to reduce the current flow of a single tab 4. An aluminum-plastic film 5 is provided at the connection between the tab 4 and the positive and negative pole pieces 1 and 2, which can avoid short circuit due to contact between the positive and negative pole pieces 1 and 2. The edge of the positive electrode sheet 1 is chamfered so as to prevent the edge of th...

Abstract

The present invention discloses high multiplying factor discharge battery. It contains positive and negative pole piece and diaphragm located between positive and negative pole piece, two tabs respectively parallel connected with positive and negative pole piece, capable of reducing single tab current, thereby making the tab assembly bearing strong current without burning-out. Compared with current technology, said invention has easy use effect. Compared with current working method, said preparing method has simple technological process and convenient operation property.

Description

【Technical field】 [0001] The invention relates to a battery, specifically a high-rate discharge battery and a manufacturing method of the high-rate discharge battery. 【Background technique】 [0002] Batteries in the prior art include positive and negative electrode sheets, a separator placed between the positive and negative electrode sheets, and tabs connected to the positive and negative electrode sheets. Existing remote-controlled toy airplanes and automobiles need high-current discharge when they are started, so that the remote-controlled toy airplanes and automobiles can be started normally. Because the existing tab itself is relatively thin, it cannot withstand the passage of a large current in an instant, so that the existing tab is melted, resulting in damage to the battery. In order to solve the above-mentioned problem of thin tabs, a conventional tab appeared subsequently. The conventional tab increases the thickness and width of the tab on the basis of the origin...
