The increasing global shift toward electric vehicles, driven by environmental concerns and government initiatives, is a primary factor boosting the demand for flame-retardant materials in EVs.
With safety regulations becoming more stringent globally, the automotive industry, including electric vehicles, is witnessing a growing emphasis on fire safety standards. This drives the need for flame-retardant materials to enhance overall vehicle safety.
The market includes various flame-retardant materials, such as polymers, fabrics, coatings, and insulation materials, designed to meet the specific safety requirements of electric vehicles.
The cost of flame-retardant materials remains a challenge for manufacturers, impacting the overall cost structure of electric vehicles. Balancing safety standards with cost-effectiveness is a key consideration for industry players.
Flame-retardant materials play a crucial role in the design of battery packs for electric vehicles. They are used in cell encapsulation and pack design to mitigate the risk of thermal runaway and fire propagation in the event of a malfunction.
Ongoing research involves the exploration of nanomaterials and advanced coatings to enhance flame resistance without compromising other material properties. These innovations aim to address both safety and weight considerations in electric vehicles.
The powder coating of an electric vehicle (EV) battery is particularly prepared for applications requiring electrical insulation and possesses dielectric insulator qualities.
Chemicals known as flame retardants are added to materials to stop or delay the spread of fire. They are employed in a variety of commercial and consumer goods to lessen the ignitability of materials.
The global EV flame–retardant material market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Increasing demand for environmentally friendly flame retardants:
Environmental concerns: Traditional flame retardants, such as polybrominated diphenyl ethers (PBDEs), have been linked to a number of environmental and health problems. PBDEs are persistent in the environment and can bioaccumulate in organisms, leading to adverse health effects.
Consumer demand: Consumers are increasingly demanding products that are made with environmentally friendly materials. This is driving demand for flame retardants that are biodegradable and less toxic than traditional flame retardants.
Development of multifunctional flame retardants:
Growing adoption of inorganic flame retardants:
Inorganic flame retardants are being increasingly adopted due to their several advantages over traditional flame retardants:
Stability: Inorganic flame retardants are stable and are not prone to decomposition, which can make them more effective in preventing fires.
Compatibility: Inorganic flame retardants are compatible with a wide variety of battery chemistries, which makes them more versatile than traditional flame retardants.
Stringent regulations and standardization efforts:
Regulatory bodies are implementing stricter safety standards for lithium-ion batteries due to the potential for fires and explosions. These safety standards are designed to reduce the risk of these incidents and to protect consumers and the environment.
Harmonization of safety standards: Regulatory bodies are also working to harmonize safety standards across different regions. This will make it easier for battery manufacturers to comply with safety regulations and will help to ensure that lithium-ion batteries are safe regardless of where they are manufactured or sold.
ALPHAGUARD FR-200 is a high-performance inorganic flame retardant based on aluminum hydroxide. It was launched in 2023 and is known for its enhanced compatibility with cathode chemistries, which are the materials used in the positive electrodes of lithium-ion batteries.
This enhanced compatibility makes ALPHAGUARD FR-200 a good choice for use in high-energy-density lithium-ion batteries, which are increasingly being used in electric vehicles and other applications.
Emerald FR-X 6000 is a nitrogen-based flame retardant that was launched in 2023. It is known for its enhanced thermal stability, which is important for preventing overheating and thermal runaway, which can lead to fires in lithium-ion batteries. Emerald FR-X 6000 is also effective at fire retardancy and is compatible with a wide range of lithium-ion battery chemistries.
A new flame-retardant engineering plastic for electromobility applications. It ensures exceptional color stability and heat-aging resistance, making it suitable for high-voltage components where color coding is safety-critical.
This product also offers high electrical insulation and eliminates halide-containing flame retardants to counteract electro corrosion. It meets stringent eMobility requirements with low halide content and fire protection class UL94 V0 at 0.4mm.
Celesta BFR 300 is a phosphorus-based flame retardant that was launched in 2023. It is known for its improved environmental friendliness, which is an important consideration for manufacturers of lithium-ion batteries. Celesta BFR 300 is also effective at fire retardancy and thermal stability, which are two essential properties for lithium-ion battery flame retardants.
Advanced Plastic Product Created by LG Chem to Stop Thermal Runaway in EV Batteries. The world’s longest fire-resistance performance was delivered by a novel plastic product created by LG Chem specifically for battery applications that can stop the spread of flame in batteries.
Thanks to the company’s unique technology and production techniques, LG Chem’s flame-retardant engineering plastic product can stop the spread of fires. A highly functional engineering plastic product composed from different composites, including polyphenylene oxide (PPO) and polyamide (PA) resin, makes up the new advanced flame barrier product developed by LG Chem.
The new product’s excellent qualities allow it to withstand flames for a longer period of time when utilized in battery components. Additionally, it has exceptional dimensional stability and keeps its shape under a variety of temperature situations.
During LG Chem’s testing, the substance was able to stop fires from spreading for more than ten minutes at 1,000°C, which is ten times longer than with regular plastics.
The most common reason for EV battery fires is thermal runaway, when a variety of stresses can cause heat to accumulate inside a battery cell. Fire can start when a battery cell gets too hot because of a short circuit brought on by things like overcharging and over discharging.
Because lithium reacts violently, the resulting fire is challenging to put out. Drivers and passengers would benefit from the use of LG Chem’s new engineering plastic product on battery components since it would give them more time to leave a moving vehicle in the event of a broken and hot battery.
A Texas-based chemical manufacturing business called Ascend Performance Compounds has created two new materials that it claims might help make electric vehicles safer and quieter.
The two new materials are the silent Starflam X-Protect and Vydyne AVS, both of which have trademarks. Each resource addresses a particular issue that Ascend calls “unique difficulties” for EV platform development by EV manufacturers.
Industry-leading flame-retardant material Starflam X-Protect can resist a direct flame of 1,100°C for 15 minutes. This is higher than the standards for aluminium and other flame-retardant materials.
In order to reduce high-frequency vibrations from noise sources like motors and compressors, the second material, Vydyne AVS, has been specially designed.
Trelleborg’s applied technologies division has developed a fire-resistant, ultra-lightweight polymer for use in areas with higher fire risks, such as protecting EV batteries.
The second material in the company’s Soteria line of protection materials is Soteria FRV. Soteria FRV, which weighs only 1.2 kg/m2 and is incredibly flexible, can be draped or wrapped around challenging profiles as well as moulded to accommodate regions of any size.
It creates lightweight protection for EV battery boxes and enclosures when coupled with Soteria FR1500 panels. It can also be used independently in applications with higher fire risks.
According to Trelleborg, Soteria FRV is flame-resistant to 1100°C for up to 90 minutes without burn through or expansion during a fire. Once it is placed, it no longer needs to be maintained, and transporting it is simple.
