The transient voltage suppressor diode protects electronic signal lines and interfaces designed to operate within specific voltage ranges. Exceeding these limits exposes sensitive semiconductors to disturbances or permanent damage. A common protection method is this specialized diode, often abbreviated as TVS. Standard ESD protection devices are made to work with high-voltage, low-energy pulses that last…

Lithium plating is the deposition of metallic lithium on the surface of the anode in a lithium-ion battery. The process is considered one of the most severe aging mechanisms in these types of batteries, and it can shorten the battery’s life and rapidly reduce its capacity. This article will discuss how anode design, anode materials,…

Electrolyte additives can help extend the life of electric vehicle (EV) batteries by stabilizing the electrode-electrolyte interfaces and mitigating the adverse side reactions that cause battery degradation over time. This article focuses on how a few specific electrolyte additives affect the lifespan of EV batteries. Improving battery lifespan with electrolyte additives One primary way electrolyte…

This final part of the multipart FAQ will explain the mechanical assembly and soldering process used to make joints during electric vehicle (EV) battery production. Although these two mechanisms are somewhat primitive in nature, they still find applications for making low-cost EVs where the makers do not have access to automation and advanced technologies. Mechanical…

This third part of the multipart FAQ will discuss magnetic pulse welding, micro-TIG, and clinching for electric vehicle (EV) battery productions. While the first two mechanisms use high temperatures to make joints, the clinching mechanism is based on applying force to create mechanical interlocking to create joints. All three mechanisms are less popular than the…

Resistance spot welding and wire bonding are popular choices for creating joints during EV battery production. However, every joining technology comes with a trade-off, giving packaging engineers room to select the appropriate one for their battery design. This is the second part of the multipart FAQ on the joining methods for EV battery production and…

Joints are important electrical and mechanical connections in producing electric vehicle (EV) batteries. They link individual battery cells to make a full battery pack. However, the process of making joints has evolved over the years due to various technologies. This first part of the multipart FAQ will discuss ultrasonic welding and laser welding, two commonly…
