Traditionally, steel and aluminium have been used to create battery housing. However, designers have recently started producing battery enclosures made of non-metals including glass fibres, carbon fibre-reinforced polymers, thermoplastics, and others.
The battery cases are mostly made of a Ni-Fe alloy that has been “contaminated” by the electrolyte, glues, and other pollutants that have clung to the surface of the case.
A battery electric vehicle (BEV) or hybrid electric vehicle electric motors are powered by a rechargeable battery known as an electric vehicle battery (EVB, often referred to as a traction battery) (HEV).
The Global EV D-LFT molded battery case 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.
Kautex Textron and Lanxess investigate D-LFT for EV battery housings The businesses have created a near-series technology demonstrator together.
The system is a large-format, all-plastic housing portion with dimensions of around 1,400 millimetres in length and width and a weight of about 20 kilograms. an underrun (underbody) protection and a housing cover.
Direct long fibre thermoplastic (D-LFT) moulding is a single-stage method that can be used to create the housing components. As the material for the D-LFT moulding compound, Lanxess has refined their Durethan B24CMH2.0 PA6 resin; Kautex Textron compounds the PA6 for the procedure with glass fibre rovings.
The housing structure is strengthened using Tepex dynalite continuous fibre-reinforced thermoplastic from Lanxess.On the other hand, plastics may completely utilise their design flexibility.
The number of separate parts in a battery enclosure can be drastically decreased by incorporating features like fasteners and thermal management components.
Because of the logistics and assembly effort being made simpler, production costs are decreased.The material is electrically insulating and resistant to corrosion, which reduces the possibility of the system short-circuiting.
The range of EVs is one benefit of the low density of polymers and their potential for lightweight construction, which also results in substantially lighter housings.
