Description

Technical Field

[0001] This utility model relates to the field of battery storage technology, and in particular to a storage device for lithium battery cell production. Background Technology

[0002] Lithium-ion battery cells are the core component of lithium-ion batteries. They consist of positive electrode materials, negative electrode materials, electrolyte, and separator. The positive and negative electrode materials are responsible for storing and releasing electrical energy, respectively. The electrolyte serves as a medium for ion transport, while the separator isolates the positive and negative electrodes to prevent short circuits. The performance of lithium-ion battery cells directly affects the energy density, cycle life, and safety performance of lithium-ion batteries, and is a key factor determining the quality and application range of lithium-ion batteries.

[0003] A search revealed that the document with publication number "CN214526064U" mentions "a storage device for lithium battery cells, including a housing and two symmetrically arranged support plates fixed to the bottom of the housing. The two sides of the housing protrude outwards to form a cuboid mounting shell. Each of the two symmetrically arranged mounting shells has a transport component inside its cavity. A placement plate for placing lithium battery cells is arranged between the two transport components. A placement layer is adhered to the top of the placement plate, and the surface of the placement layer has several evenly distributed placement grooves, each placement groove being a cuboid structure." In use... The driven pulley rotates, driving the transmission rollers to rotate, which in turn moves the lifting conveyor belt on the surface of the two transmission rollers. The movement of the lifting conveyor belt moves the placement plate on its surface, which in turn moves the placement plate on the placement plate. By controlling the forward and reverse rotation of the drive motor, the storage and retrieval of the battery cells are achieved. The whole process is highly mechanized and convenient. However, during the storage and transportation of lithium batteries, before the lithium battery cells are assembled into batteries, their structural stability is relatively weak. If they are subjected to external interference, the battery cells are easily damaged, so it is necessary to protect the battery cells as much as possible.

[0004] Therefore, we provide a storage device for lithium battery cell production to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The battery storage mechanism allows for easy replacement of the battery holder when needed, based on the size and number of battery cells. This improves efficiency. The rubber pads, thanks to their material properties, reduce hard impacts on the battery cells during movement, preventing damage and isolating them from external static electricity and current, thus enhancing safety. The heat-insulating coating isolates heat from the layer below, especially reducing the likelihood of other cells spontaneously combusting if one cell ignites.

[0017] 2. Through the battery storage mechanism, when a large-scale spontaneous combustion occurs in the internal battery cells, the temperature inside the storage box will rise sharply. At this time, the temperature sensor will detect the temperature change and alert the staff to carry out rescue in time. At the same time, the fire extinguishing foam pump box will be controlled to protect itself. The fire extinguishing foam pump box will spray a large amount of non-flammable foam through the foam nozzle to wrap the battery cells, thereby preventing them from affecting the battery cells in other storage boxes.

[0028] Furthermore, the battery cell placement assembly 21 includes a battery placement frame 211, an inner frame 212, a rubber pad 213, and a heat insulation coating 214. The inner side of the storage box 1 is connected to the battery placement frame 211 by a slot. The inner side of the battery placement frame 211 is welded to the inner side of the battery placement frame 212. The outer side of the inner frame 212 is wrapped with a rubber pad 213. The lower side of the battery placement frame 211 is provided with a heat insulation coating 214. When needed, the detachable battery placement frame 211 can be replaced according to the size and quantity of the battery cells, which can improve the efficiency of use.

[0029] Furthermore, the rubber pad 213 and the inner frame 212 are bonded together, and the rubber pad 213 and the inner frame 212 fit tightly together. When needed, the rubber pad 213 can reduce the hard impact of the battery cell during shaking by relying on its own material properties, avoid damage to the battery cell, and also isolate external static electricity and normal current, thereby improving safety.

[0030] Furthermore, the heat insulation coating 214 is bonded to the battery placement frame 211, and the heat insulation coating 214 and the battery placement frame 211 correspond one-to-one. When in use, the heat insulation coating 214 can isolate heat from the next layer. In particular, if one of the battery cells spontaneously combusts, it can reduce the possibility of other battery cells being heated and spontaneously combusting as well.

[0031] Furthermore, the battery cell monitoring component 22 includes a top cover 221, a fire-extinguishing foam pump box 222, a power supply battery 223, a foam sprayer 224, foam nozzles 225, a battery limiting pad 226, and a temperature sensor 227.

Foam nozzles 225 are located on the inner side of the top cover 221. Battery limiting pads 226 are located on the inner side of each foam nozzle 225. A temperature sensor 227 is located in the middle of the battery limiting pad 226.

[0036] Working principle: A storage device for lithium battery cell production is moved to the working position. In use, the first step is to insert the battery cells into the slots formed by the inner frame 212 and the rubber pad 213 inside the battery placement frame 211. Then, the battery placement frame 211 with the battery cells is placed into the storage box 1. The heat insulation coating 214 isolates the upper and lower sets of battery placement frames 211. The second step is to insert the top cover 221 into the storage box 1 and fix it with the box clip 23. The third step is to supply power to the whole unit with the power supply battery 223. When the temperature sensor 227 senses a drastic change in the temperature inside the storage box 1, it will control the fire extinguishing foam pump box 222 to spray a large amount of foam from the foam nozzle 225. Then, the siren 224 will sound an alarm. This completes the use process of the storage device for lithium battery cell production.
