Choosing between aluminium and copper is one of the first decisions in any busbar design. Both materials are capable conductors, but they make very different engineering trade-offs. This page sets them side by side across the properties that matter most — electrical, mechanical, thermal, and practical. Material Properties at a Glance The table below compares … Read more
We have just received the specification sheet for the JLi Battery Co 37Ah 4695 cell and it is really interesting. This is a 335Wh/kg cylindrical cell with a Ni-rich NMC cathode + Silicone Carbon anode. The cells are using aluminium shell to enable the lightest weight and highest thermal performance. The Welding instructions for this … Read more
AION Engineering INC Role of Tabs in Current Flow During discharge, the current generated by electrochemical reactions flows through the sequence: Active Material → Conductive Additive → Current Collector → Tab The tab serves as the final current-carrying element in this path. Its current-carrying capacity is therefore a critical factor that affects both electrical efficiency … Read more

In previous articles we’ve highlighted the benefits of aluminium cell housings for 4680 battery cells like improved thermal management and gravimetric energy density and explored the structural performance of 4680 cans made from Speira ION Cell 3-CB and Speira ION Cell 3-CS1,2,3. It has been shown that high strength aluminium grades like Speira ION Cell … Read more
Battery electric vehicles (BEVs) are seen as the cornerstone of a more sustainable future of transport. Batteries are the key technology for powering these vehicles. However, the production of battery cells involves energy-intensive processes that result in significant CO2e emissions. As a result, BEVs have higher carbon footprint in production than internal combustion engine (ICE) … Read more
Exploring different battery tray designs in the automotive industry and three main design concepts have emerged in the design of metallic battery trays: Building on Posts from Matthias Biegerl [1] and Luca Greco [2]. Deep-Drawn Sheet Metal Pans This process involves forming the housing with deep-drawn sheet metal pans and sealing it with a lid. … Read more
Recent industrial and academic studies have shown that aluminium cell housings can provide several benefits in terms of thermal management and gravimetric energy density in particular1,2,3. However, as Cell-To-Pack and Cell-To-Chassis approaches arise the battery cell and therefore, the battery cell housing, become part of the structure of the battery electric vehicle contributing with their … Read more
for Cell Contacting Systems and Busbars Aluminium busbar products are used in manifold applications in batteries and battery systems due to their favourable structural, physical, and chemical properties. When it comes to cell contacting systems and busbars, electrical (and thermal) conductivity are decisive for balancing component resistance and cross-section to meet the designed space. However, … Read more
Benefits of Aluminium Cell Housing for Cylindrical Li-ion Batteries is based on a 4680 cell concept. The battery industry is targeting larger cell formats, which enable simplified module design and cell-to-pack or even cell-to-chassis solutions. In this regard, hard case battery cells and in particular cylindrical cells will play an important role in enabling the … Read more
