Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lithium battery, concretely is a press type welding injection molding minimalist terminal structure cover plate. BACKGROUND

[0002] One of the significant advantages of lithium batteries is their long cycle life. Under appropriate charging and discharging conditions, the battery can be used for several years without significant performance degradation. For small current discharge appliances, this long life characteristic greatly enhances their market competitiveness. Therefore, long cycle life not only prolongs the use time of the battery, but also improves its economy and practicability. One of the significant advantages of lithium batteries is their high open-circuit voltage. This high voltage characteristic makes it easy to form a battery power pack with lithium batteries to meet the needs of different devices. One of the significant advantages of lithium batteries is their extremely low self-discharge rate. At room temperature, the self-discharge rate of a lithium ion battery with full charge for one month is about 3% per month. Lithium batteries can still maintain a high amount of electricity after a long period of storage, which is much better than other types of batteries. This low self-discharge rate not only prolongs the service life of the battery, but also reduces energy loss and improves efficiency. Lithium batteries have significant advantages in environmental protection. Compared with ordinary lead-acid batteries, lithium ion batteries use high environmentally friendly raw materials, avoiding the use of heavy metals harmful to the human body and the environment. More importantly, from production to use to scrap, lithium batteries do not produce toxic heavy metal substances such as lead, mercury, and cadmium, ensuring environmental friendliness. This pollution-free characteristic makes lithium batteries a more green and environmentally friendly energy choice. One of the significant advantages of lithium batteries is their high energy density. Due to this high energy density, lithium ion batteries are half lighter than nickel-cadmium or nickel-hydrogen batteries with the same capacity, and their volume is also greatly reduced. This characteristic not only increases the standby time of mobile phones, but also improves the cruising range of electric vehicles. In addition, high energy density also means that lithium ion batteries consume fewer resources, which is more environmentally friendly and resource-efficient.

[0003] The thickness of the cover plate of the existing lithium battery of different models and different sizes will also be different, so the connecting terminal also needs different specifications, which will increase the manufacturing cost and easily cause waste. INVENTION CONTENTS
