Fibre-plastic composites EV battery packs, produce in just 2 minutes
The Scientists from Fraunhofer Institute for Structural Durability and System Reliability (LBF) has developed a lightweight battery pack to reduce the overall weight of e-car batteries.
These new battery packs are made up of fibre-plastic composites that reduce the weight of the battery to 40 per cent compared to a casing made of aluminium.

“This design not only reduces the moving mass of the electric vehicle but also increases its range and dynamics thanks to additional integrated functions,” wrote the LBF in a press release. The institute said that these new batteries can be manufactured within two minutes and at low cost.
Currently, the electric vehicles battery packs are very heavy because of the large number of battery cells to get that desired range. The whole battery can weigh several hundred kilogrammes, making up more than 30 per cent of a car’s total mass, said the institute.
How much is the car is heavy more energy is needed to operate it. Germany in September 2020 has registered more than 20,000 pure electric cars in a month for the first time.
Recently, EV battery manufacturer InoBat Auto has unveiled the world’s first artificial intelligence electric vehicle battery “InoBat” with a higher energy density and increases the vehicle’s range for about 20%. This battery is a combination of both Artificial Intelligence (AI) and High Throughput (HTP) technology.
The new production process helps the batteries to get quicker and more efficient which results in a 20% increase in operational range when compared to the conventionally-made batteries. These batteries reduce the dependency of the rare metal such as cobalt which can provide high energy density.
InoBat units will provide an energy density of 265-watt hour (Wh) per kg by the end of 2021 and will increase to 298 Wh per kg by mid-2022, and up to 350 Wh per kg by the end of 2023. The overall target is 500 Wh per kg. The company will also slowly remove nickel from its batteries.
