Benefits of Aluminium Cell Housings for Cylindrical Lithium-ion Batteries

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 named developments. Tesla’s announcement of a tabless 4680 cylindrical LIB has triggered … Read more

Joining Techniques for Pack Enclosures

Author: David G. Kilburn & Nigel Taylor As I posted the other day, there are a lot of “boring” battery topics that often get overlooked and producing the battery housing (sometimes referred to as battery tray or box) is no exception! To house a battery you need a high quality, leak proof container that can … Read more

10 things about SSBs that you are often not told

Author Dr. Simon Madgwick of Nuvvon Inc. As an overview, this post cannot cover every possibility or explain in depth. Nonetheless these 10 topics give a reasonable overview of solid-state batteries in terms of what is less transparent in the publicity and hype of solid state. To be clear, we need solid state batteries, but … Read more

2022 Tesla Semi Specifications

In order that we can understand the specifications of the battery pack it is necessary to at first piece together the vehicle. Warning: this page is going to have updates/amendments over time and some values are likely to be an estimate. Specifications A typical single tank semi can do circa 550miles and tanks hold up … Read more

Tesla 4680 Cathode Porosity

Indicative numbers for the Tesla 4680 cathode porosity, estimated based on 2D images of the Batch 1 and 2 cells originally analysed for The Limiting Factor by the Laboratory for Energy Storage and Conversion, UC San Diego. This image analysis and estimation was performed by Addionics based on the original Tesla 4680 cell benchmarking. Analysis … Read more

Photo Etching

ACE busbars

Whether prototyping or creating busbars for production runs we often want high quality parts and this is where photo etching comes into it’s own. Advanced Chemical Etching take us through the process of photo etching and how this can be used to create high quality aluminium or copper parts. We are concentrating on busbars, but … Read more

Proving new Chemistry

cellerate system

One of the fundamental steps in proving new chemistry is making small cells that can be reliably charged and discharged. These small cells are assembled in argon filled gloveboxes. They are small and very fiddly to assemble. However, they need to be precisely built to reduce variation in data caused from physical mis-alignment of electrodes which … Read more

Smart Battery Development

smart battery design

Prof James Marco WMG Energy Group Significant advances have been made in recent years in our understanding of the electrochemical performance of lithium-ion batteries (LIBs), their degradation, safety, manufacturability and recyclability – in part, through innovations in experimental methods and mathematical modelling. WMG is at the heart of this research through our involvement in projects … Read more
