Thin type lithium-manganese soft packing battery pack and manufacturing method thereof

Abstract

The invention discloses a thin type lithium-manganese soft packing battery pack which comprises a paper board, the single side of which is coated with blister varnishing, two large circular holes are arranged in one end of the paper board, the central connection line of the two large circular holes is parallel to the end part edges of the paper board, two suspension holes are arranged on the other end of the paper board, metal sheets cover and are glued on the two large circular holes respectively, two thin type lithium-manganese soft packing batteries which are connected in series by a positive temperature coefficient (PTC) thermistor are arranged above the metal sheets, insulating face pads are arranged below the PTC thermistor, one battery positive electrode tab and another battery negative electrode tab, two ends of the PTC thermistor are connected with the one battery positive electrode tab and another battery negative electrode tab, one electrode negative electrode tab is connected with one metal sheet, another positive electrode tab is connected with the other metal sheet, and a blister packaging enclosure welded together with the paper board is arranged above the two batteries; the invention further discloses a manufacturing method for the thin type lithium-manganese soft packing battery pack, and the battery pack manufactured by the invention has good environment friendliness and safety properties, as well as light weight, small thickness and good large-current discharge capacity.

Description

technical field [0001] The invention relates to a structural design of a thin lithium-manganese flexible package battery pack and a manufacturing method of the battery pack. Background technique [0002] In the early 1990s, when digital cameras had not yet become popular, a camera that could shoot instantly won the favor of consumers, and people gave it an easy-to-understand name——Polaroid (also known as instant shoot well). Although its photo paper is expensive, thousands of tourists still enjoy it in many tourist attractions. After the popularization of digital cameras, Polaroid gradually faded out of the general consumer market due to the high cost of shooting and the inconvenience of carrying. But among some bourgeois men and women and camera enthusiasts, Polaroid still has a unique charm, making this old-fashioned camera still glow in some groups.

Although the price of its photo paper is high, thousands of tourists still enjoy it in many tourist attractions

After the popularization of digital cameras, Polaroid gradually faded out of the general consumer market due to the high cost of shooting and the inconvenience of carrying.

But among some bourgeois men and women and camera enthusiasts, Polaroid still has a unique charm, making this old-fashioned camera still glow in some groups

Polaroid cameras consume a lot of power, and ordinary dry batteries cannot meet their requirements, so they have always used power-type lithium-manganese batteries as power sources (such as CR2 and CR123A, etc.)

However, as a professional industrial battery, lithium-manganese batteries are not easy to buy on the market, and there are hidden dangers in the safety of power-type lithium batteries. As a common civilian electronic product, the safety of cameras is particularly important. Therefore, the design of a It is very meaningful to have a Polaroid camera battery that can be built into a photo paper box with high power discharge capability and ultra-high safety.
