In the face of the increasingly severe global "energy crisis" and increasingly stringent environmental protection requirements, lithium batteries have become an outstanding representative of new energy due to their low energy consumption and pollution-free advantages. In recent years, the influx of capital has driven the investment expansion of new energy automobile industry chain projects, and the new energy power battery industry represented by lithium-ion batteries has undergone structural expansion. Lithium batteries are the core components of new energy vehicles, accounting for 40% of the total production costs of new energy vehicles. In recent years, the vigorous development of new energy electric vehicles at the policy level and other measures have also enabled my country's lithium battery industry to enter a period of rapid development. It is estimated that by 2023, the global demand for power lithium batteries will reach 511GWh, with a compound annual growth rate of 36.7% in the next five years. For the decoration of the lithium battery factory, the workshop design must be done in the early stage, because the production of lithium batteries requires a clean workshop environment, and because of its chemical composition, special attention should be paid to the fire protection system during the decoration, product production and storage. the design of. Taking a lithium battery plant project in Xidi Shanghai as an example, I will introduce the details of the workshop design and decoration of the lithium battery plant decoration.

The decoration design of the lithium battery factory plant is mainly embodied in six aspects, namely: personnel and material layout, determination of cleanliness level, good fire protection design, determination of space pressure difference, determination of space air balance, and determination of mechanical system layout.

Staff and material layout:

The biggest source of pollution in a lithium battery factory is personnel and materials, so the relevant layout must be done before plant decoration and workshop design. Specifically, the key lies in the isolation of personnel access and passages. The core area can only be accessed by a single, and can no longer lead to other areas. Also evaluate material entry and exit routes and containers, and material process isolation to avoid cross-contamination.

Determine the cleanliness level:

The cleanliness levels of lithium battery plants are 1,000, 10,000, 100,000, and million. The higher the cleanliness level, the greater the construction, maintenance and energy costs. Therefore, the cleanliness must be determined first when designing the workshop grade. In addition, the cleanliness level of two connected workshops cannot exceed two orders of magnitude.

Do a good job of fire protection design:

Lithium battery factories are different from other combustibles. Due to the special physical and chemical composition of the battery itself, the raw materials for lithium battery production will undergo a violent chemical reaction after a fire, which generates huge heat. The fire-fighting system is mainly designed for raw material storage rooms, semi-finished products storage rooms, and finished product storage rooms with fire hazards such as electrolyte.

Determine the space pressure difference

How to prevent external pollution sources from entering the lithium battery factory workshop? The air pressure in the workshop must be controlled within a reasonable range. However, through clinical experiments, it is known that the pressure difference between the connected workshops is 0.03-0.05. Note that the pressure difference is directly proportional to the energy cost, and the higher the pressure difference, the more difficult it is to control. Determine the space air balance The air in each workshop of the lithium battery factory must be in a balanced state. The balance mentioned here mainly refers to the equalization of the air entering the space (supply, infiltration) and the air leaving the space (exhaust, filtration, return).

Determine the layout of the mechanical system

Many factors will affect the layout of the mechanical system of a lithium battery plant, for example, such as the climate conditions in the area where the lithium battery plant is located, the building structure and space size of the plant, the cleanliness level and energy cost, and the total decoration budget. Therefore, before the renovation of the lithium battery factory, the designer must determine the layout of the mechanical system based on these variables.

Paying attention to the above key content, coupled with the qualified and experienced design and construction team, the decoration design of the lithium battery factory can be perfectly controlled. In terms of specific implementation, the EPC general contractor will design and construct The scope is the integration of interior structure, steel structure grid, ground, HVAC, exhaust, power, lighting, weak current, air pressure, cooling water, and pure water projects. Choosing an EPC engineering service provider such as CEIDI has its own production base. In addition to the integration of design and construction, the furniture and facilities in the workshop can also be matched simultaneously, which can save a lot of time and money for the company.

CEIDI Xidi Lithium Battery R&D Laboratory Construction and Decoration Project
