Problems solved by technology

[0004] The battery of the existing drone is usually fixed by the cover of the battery compartment. When the cover falls off accidentally, the battery is easy to fall off from the inside of the battery compartment, causing the drone to crash because it has no kinetic energy and cannot fly. Simply protecting the working performance of the battery at low temperature through the low temperature resistance of the battery itself cannot effectively guarantee the working performance of the battery at low temperature. Therefore, we propose an ultra-low temperature high-performance lithium iron phosphate power battery

Embodiment 1

[0037] see Figure 1-7 As shown, an ultra-low temperature high-performance lithium iron phosphate power battery includes a battery body 1, the battery body 1 can be installed inside the battery compartment of the drone, and one end of the battery body 1 is provided with a terminal electrically connected to the drone head 2;

[0038] Here, the battery body 1 improves its performance in a low-temperature environment through the following methods:

[0039] 1. The ion diffusion performance of the positive electrode material at low temperature, the method of coating the surface of the active material body with a material with excellent conductivity improves the conductivity of the positive electrode material interface, reduces the interface impedance, and reduces the side reactions between the positive electrode material and the electrolyte. Stable material structure;

[0040] 2. Reduce the particle size of the material and shorten the Li+ migration path. This method will increas...

Abstract

The invention discloses an ultralow-temperature high-performance lithium iron phosphate power battery, and belongs to the field of unmanned aerial vehicle batteries, the ultralow-temperature high-performance lithium iron phosphate power battery comprises a battery body, the battery body can be installed in an unmanned aerial vehicle battery compartment, and one end of the battery body is provided with a power connection end electrically connected with an unmanned aerial vehicle; the outer side of the battery body is fixedly connected with at least one auxiliary adjusting mechanism, the auxiliary adjusting mechanism is used for providing auxiliary force between the battery body and the inner wall of the battery bin to fix the battery body and heat the battery body, and the auxiliary adjusting mechanism comprises a protective shell fixed to the outer side of the battery body; according to the low-temperature battery box, the probability that the battery body falls off from the interior of the battery box when the unmanned aerial vehicle flies can be effectively reduced, the power supply stability of the unmanned aerial vehicle is improved, the probability that the unmanned aerial vehicle crashes is reduced, and the working performance of the battery body at the low temperature is guaranteed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle batteries, and more specifically, relates to an ultra-low temperature and high-performance lithium iron phosphate power battery. Background technique [0002] For example, the lithium iron phosphate battery disclosed in the application publication number CN109119686A improves the low-temperature performance, normal temperature and high temperature cycle performance of the lithium iron phosphate battery, and effectively prolongs the service life of the lithium iron phosphate battery; [0003] Among them, because drones often fly in high-altitude environments, and the flight environment temperature is low, lithium iron phosphate batteries are often used, and they are installed inside the battery compartment of the drone and connected to the terminal of the drone. Connect to provide power to the UAV; [0004] The battery of the existing drone is usually fixed by the cover of the battery compar...
