While lithium-ion batteries dominate the electric vehicle market, there are continuing concerns about shortages of raw materials, costs, and extraction and mining practices. Lithium production is expensive and it’s not particularly eco-friendly.
Lithium-ion batteries have been powering our devices and electric vehicles for years, but solid-state batteries are now heralded as the next big thing. But how accurate is that claim?
Introduced in 1995, pouch cells have always presented a unique design, where the battery is enclosed in a soft plastic film instead of a rigid casing like cylindrical and prismatic cells.
In this article, we discuss how they have evolved over the years and where they are headed.
All over the world, automakers and OEMs are using structural adhesives to produce the next generation of cars. For those new to this subject, structural adhesives can seem complex to implement
Ultrasonic welding and laser welding have emerged as prominent technologies for making busbar connections in EV battery modules. While both technologies can be automated and offer the quality and precision needed for battery manufacturing, there are important differences to consider
The battery is the most expensive part in an electric car, so a reliable manufacturing process is important to prevent costly defects. Electric vehicle batteries are also in high demand, which puts pressure on manufacturers to maximize production without compromising quality. As a result, robot automation is almost everywhere during battery manufacturing.
While laser welding is known for its ability to produce high-quality welds at high speeds, integrating this technology into EV battery production lines presents unique challenges.
EV manufacturers need to work with laser and automation experts that know how to address these challenges if they want to achieve a high yield and produce at a high rate.
Thermally conductive adhesives such as tapes, films, and glues are used to bond heat-generating components to heat sinks. Thermal adhesives not only conduct heat, but they can also provide structural integrity, electrical insulation, or electrical conductivity.
In EV battery manufacturing, adhesives are increasingly used to bond components. They are replacing mechanical fasteners as well various joining technologies. Unlike screws, bolts, and welding, structural adhesives provide a range of benefits beyond the bond.
Battery thermal management is essential in electric vehicles and energy storage systems to regulate the temperature of batteries. It uses cooling and heating systems to maintain temperature within an optimal range, minimize cell-to-cell temperature variations, enable supercharging, prevent malfunctions and thermal runaways, and maximize the battery’s life.
The rotor transfers power from the batteries to the wheels of an electric vehicle. Manufacturing rotors with the latest technologies improves the motor’s efficiency in many ways.
We often think of the electrification of the industry as a movement away from fossil fuels to reduce global emissions. But there are other, less obvious implications that are affecting electric motor manufacturers and consumers.
