A flame-retardant thermoplastic composition that combines homopolymers, copolymers, and ammonium polyphosphate is used to make battery casings.
The thermoplastic composition has enough ammonium polyphosphate to give it flame retardance. Other ingredients include melamine, which serves as a blowing agent, and polyol, an intumescent char-forming agent.
It is possible to add antioxidants, releasing agents, carbon black, reinforcers, and other compounds. Alternately, the battery enclosure is made of a polymer composition that combines a polypropylene component and a fire-retardant component that contains halogens.
Most battery casings are made of plastic.Batteries used in phone systems, computers, electrically powered vehicles,etc.
can use these battery casings. The majority of battery casings are, however,also rather flammable in general. When burning, they can produce thick, poisonous, and corrosive smoke.
They can also quickly lose their mechanical strength when exposed to heat, and they can spread fire through dripping.
These are some risks that could be particularly important when using batteries for computers, phone systems, and electrically propelled vehicles.
Different methods have been devised to give polymers flame retardancy or fire resistance. Plastic products can acquire fire-resistant qualities by combining polymer elements with one or more fire retardants.
The current invention pertains to a flame-retardant battery casing, a composition for making battery casings that is flame-retardant, and a method for making a battery casing from the composition. A flame-retardant element of the composition is non-halogenated in the preferred embodiment.
Because they are used as backup electrical systems during and after fires or floods, the batteries using the present invention’s casings must be one to two volts per cell, meet standards for toughness and durability, contain toxic or hazardous materials, and be sealed in relation to their environment.
The Global EV battery Flame Retardant plastics market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
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 utilised 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. Lithium interacts rapidly with water, making the resulting fire 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.
