Currently, most energy storage containers use polyurethane foam for insulation, and its thermal insulation effect is very obvious. However, with the continuous improvement of environmental awareness, the use of polyurethane foam has been subject to certain restrictions. In contrast, melamine foam, as a material with good environmental protection, fire protection, sound insulation and thermal insulation properties, has attracted widespread attention in the energy storage industry. Melamine resin foam does not contain any halogenated hydrocarbons, flame retardants, or toxic heavy metals, and has excellent mid- and high-frequency sound absorption properties (0.95NRC). As well as a wide range of weather resistance (negative 180 degrees Celsius to 200 degrees Celsius), it still maintains a stable physical and chemical structure under high and low temperature conditions, while providing excellent thermal conductivity (thermal conductivity coefficient, 0.035 W/ (m*K)).

Performance advantages of melamine foam in energy storage

Melamine foam has excellent thermal insulation properties:
Melamine foam is a porous material whose internal pore structure can reduce heat conduction, thereby effectively isolating heat transfer. Compared with traditional thermal insulation materials, melamine foam has a lower thermal conductivity and better thermal insulation effect. In energy storage systems, melamine foam can be applied to the shells, pipes and other parts of energy storage equipment to reduce heat loss and improve energy storage efficiency.

Melamine foam offers stable chemical properties:
Energy storage equipment often needs to work under extreme environmental conditions, such as high temperature, low temperature and humidity. Melamine foam has excellent temperature resistance and moisture resistance, and can maintain stable performance in extreme environments. It makes melamine foam an ideal thermal insulation material for energy storage equipment, which can effectively protect the internal components of the energy storage system and extend its service life.

Melamine foam also has lightweight characteristics:
Compared to traditional thermal insulation materials, melamine foam has a lower density and is lighter in weight. This not only reduces the load on energy storage equipment and improves the convenience of its transportation and installation, but also saves material costs.

Melamine foam can effectively solve the following problems in the field of energy storage

Energy storage batteries have the characteristics of high energy density. When thermal runaway occurs, it is easy to cause fires to spread rapidly and even cause explosion hazards. Melamine foam has good fire retardant properties without adding flame retardants and can effectively slow down the spread of fires in energy storage batteries.

The storage temperature of energy storage batteries is usually -25°C~55°C. The thermal conductivity of melamine foam is 0.035W/(m*K). It has excellent thermal insulation performance and ensures the safe and efficient operation of the energy storage system.

Melamine foam has excellent mid- and high-frequency sound absorption properties (0.95NRC) and can effectively achieve sound insulation and noise reduction.

Melamine foam is mainly foamed from melamine polyformaldehyde resin. It does not contain other chemical substances, is also non-fiber material, does not contain any dust, does not contain any halogenated hydrocarbons, flame retardants, or toxic heavy metals, which helps environmental protection.

In addition, melamine foam is a kind of elastic organic plastic foam with high open-cell three-dimensional network structure, which is made of Melamine polyformaldehyde resin by microwave foaming. In addition to easy cutting or CNC processing, it can also be combined with other materials, such as hot-pressed molded parts with non-woven fabrics, aluminum foil, PVC and other materials.

Compared with traditional thermal insulation materials, the thermal insulation performance of melamine foam is several times that of traditional materials. When a single energy storage cell undergoes thermal runaway, the melamine foam between battery cells and battery modules exerts its excellent thermal insulation properties at high temperatures to block a large amount of heat from being transferred to adjacent cells and modules, which greatly reduces the risk of equipment thermal runaway and also increases the system fault shutdown time.

At the same time, since battery performance is affected by temperature, the battery charges slowly and consumes power quickly when the temperature is too low in winter. Melamine foam can also maintain the temperature of the energy storage battery within an appropriate range, ensuring the safe and efficient operation of the energy storage system in low-temperature environments in winter.

In the field of energy storage, the selection of thermal insulation materials is very important. Common energy storage types include battery energy storage, thermal energy storage and compressed air energy storage. Different energy storage methods have different requirements for the performance of thermal insulation materials. For example, battery energy storage requires good thermal insulation of the battery to prevent overheating or overcooling from shortening the battery life; thermal energy storage requires keeping the stored high-temperature energy from being lost for a long time to reduce energy loss. Therefore, when selecting energy storage thermal insulation materials, it is necessary to comprehensively consider the actual conditions of the equipment and select suitable thermal insulation materials.
