High-safety lithium ion battery diaphragm and lithium ion battery

Abstract

The invention relates to the technical field of batteries, and concretely relates to a high-safety lithium ion battery diaphragm and a lithium ion battery. The high-safety lithium ion battery diaphragm comprises an upper cover, the upper cover is provided with a battery compartment, and the battery compartment is provided with an energy storage mechanism; the upper cover is provided with a reset mechanism, the reset mechanism is connected with a heat dissipation mechanism, the reset mechanism drives the heat dissipation mechanism, and the upper cover is provided with an insertion mechanism; a carrying mechanism is arranged on the upper cover; through the arrangement of the energy storage mechanism, battery blocks can be conveniently and well separated, and the filled buffer material plays a role in buffering the battery, so that the safety of the battery is improved; through the arrangement of the insertion mechanism, accidental separation in the charging process can be effectively avoided; and through the design of a reset mechanism, a heat dissipation mechanism can be conveniently driven, so that the heat dissipation mechanism can facilitate air convection between the upper cover and the outside during charging, the effect of reducing the heat of the battery can be achieved, and safety accidents caused by high temperature are reduced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a high-safety lithium-ion battery diaphragm and a lithium-ion battery. Background technique [0002] The wide application of lithium-ion batteries has promoted the development of electric vehicles. As the core components of batteries, diaphragms and supporting components are ushering in a new round of development peaks. Compared with previous batteries, batteries using lithium-ion batteries have greatly increased the unit volume. The energy density inside improves the battery life of electric vehicles, and the battery life of electric vehicles is also greatly guaranteed. [0003] However, when the existing lithium battery is used in the electric scooter, it only has the function of detachable connection with the electric scooter. Generally, an external lifting handle is used, which takes up the usable space of the electric scooter, and the battery is basically integrated. The ...

[0003] However, when the existing lithium battery is used in the electric scooter, it only has the function of detachable connection with the electric scooter. Generally, the external lifting handle is used, which takes up the usable space of the electric scooter, and the battery is basically integrated The design does not have the function of physically lowering the battery temperature when the battery is charging, which may easily cause battery charging safety accidents caused by temperature, and the charging plug is mostly connected in pairs, and the plug is easy to plug after frequent repeated plugging and unplugging. Loose, the mating effect is significantly reduced, and it is easy to cause poor contact
