What harm does lithium battery factory do to the body?

Hello, first of all, it contains a certain amount of radiation because it contains cadmium, which can cause osteoporosis. It is recommended to eat more foods containing calcium, and lithium batteries generally survive in a nitrogen-free space. Decomposition will occur if you leave this space and come into contact with water, so try to take protective measures! !

What are the key points in the design of lithium battery R&D laboratories?

1. The choice of nitrogen source is very important. Nitrogen-containing substances are commonly used, such as nitrogen, ammonia, etc.

2. During the preparation process, the functional groups on the surface of plasma-treated graphene are very active and do not last long, which requires strict requirements for equipment and experimental conditions.

3. When used in balithium-sulfur batteries, it is necessary to pay attention to the impact of conductivity, specific surface area, pore structure and other parameters of nitrogen-doped graphene on battery performance.

What harm does a lithium battery factory do to the body?

(1) Floor plan design - SICOLAB

1. must be reasonably designed. People flow, logistics, wastewater flow and fire escape routes, as well as inspection passages, are designed according to the needs of the owners.

(2) Decoration and decoration design--SICOLAB

1. The selection of laboratory separation ceiling materials should meet the requirements of airtightness, heat preservation, thermal insulation and environmental protection. for production or research and development. Flame retardant, moisture-proof, dust-proof, corrosion-resistant, durability, easy cleaning and other requirements, liquid injection, formation and aging areas must be made of non-combustible materials.

(3) Design of the processing pipeline - SICOLAB

1. Bottled asphyxiating gases such as helium and argon used for production and research and development of lithium-ion batteries must be stored in the factory. dedicated room.

2. When the nitrogen purity is less than or equal to 99.999%, the inner wall of the BA grade stainless steel pipe should be bright annealed.

3. Helium and argon used in the production of lithium-ion batteries must be supplied by compressed bottled gas and its purity must be greater than or equal to 99.99%. Grade 316BA or higher.

(3) Design of the NMP electrolyte recovery and supply system - SICOLAB

1. The electrolyte belongs to class A hazardous substancesand B, therefore precautions must be taken into account in the electrolyte transport pipeline. Leak-proof design is a necessary guarantee for safe production. In order to prevent leakage at the pipeline connection parts, anti-leakage measures should be taken at the same time, an emergency stop valve should be installed on the main electrolyte supply line. In the event of a leak, the transport of the electrolyte will be interrupted. be cut off urgently to avoid large-scale electrolyte leakage and environmental damage and eliminate safety hazards.

2. NMP supply and wastewater pipes shall be made of stainless steel seamless steel pipes or titanium alloy pipes. The pipeline connecting the temporary electrolyte storage room to the liquid injection machine should have leak prevention measures, and an emergency stop valve should be installed.be installed on the main electrolyte supply pipe.

(4) Ventilation, air conditioning and purification design--SICOLAB

1 The drying room and general air-conditioned room should be designed with separate air conditioners;

2, Dry rooms with large dew point temperature differences should be designed with separate air conditioners;

3. Dry rooms with cleanliness requirements and dry rooms without cleanliness requirements should be designed with separate air conditioners;

4, the positive electrode production workshop and the positive electrode production workshop Negative electrodes should be designed with separate air conditioners;

5. R&D workshops that produce large amounts of dust should be designed with independent air conditioners and dust collectors. treatment devices.

6. The difference in static pressure between drying rooms with points of rdifferent exposure must not be less than 5Pa;

7. not be less than 5Pa;

p>

8. The static pressure difference between the drying room and the outside should be greater than 10Pa.

9. Warehouses of raw materials and auxiliary materials without temperature and humidity requirements must be equipped with a complete mechanical ventilation system.

10. An accidental ventilation system should be designed in the temporary electrolyte storage room and the liquid injection room, and the number of accidental ventilation should not be less than 12 times/h.

11. The nitrogen methylpyrrolidone (NMP) exhaust system shall be designed as an explosion-proof system.

12. When the required dew point temperature in the drying room is lower than -50°C, a two-stage dehumidification treatment system should be used.

13. The rate of air leakage from the treatment area andof the regeneration zone in the final dehumidification section shall not be more than 0.5%.

The lithium battery factory is divided into two parts:

If it makes battery cells, the elements inside the battery cells are harmful to the body human. It is not recommended to go there. there you must wear a gas mask or mask when working. . . . . . Before, without knowing it, I would open a bucket of battery ingredients and smoke it. I couldn't eat for a whole day. As expected, I wouldn't die unless I attempted suicide. . . . .

If you do PACK, it has virtually no impact on the body (some workstations need to be exposed to organic solvents), which is what I do. . . .
