from chemistry to pack
The Battery Data Behind IAA Transportation 2026 IAA Transportation 2026 ran in Hannover from 15 to 20 September, and electrification was the theme running through most of the exhibitor announcements: Volvo, DAF, MAN, Scania and SANY all had electric truck news on the stand. The one battery-specific launch worth digging into in detail is CATL’s … Read more
The CATL 24V Naxtra is a sodium ion based pack designed for commercial truck engine start and operation. CATL claim that this pack is able to operate the air conditioning all night and still start the vehicle in the morning [3]. The motor show mock up and CAD images show just 2 terminals for power … Read more
The Hina NaCR32140-MP10 is a sodium ion based chemistry cylindrical cell with a capacity of 10Ah. In the original release of this cell we saw a specification showing 12Ah (left image). However, the volume production shows this 32140 format is a 10Ah Sodium Ion cell. Key Metrics The maximum power has been calculated based on … Read more
A look at the Sodium Ion Cell Manufacturing Process, but perhaps more usefully a look at the differences compared to the lithium based cell manufacturing processes. Note: this is a work in progress as we gather information and knowledge. Hence some sections are empty because we do not know, not because there are no differences. … Read more
An initial look at the sodium ion battery pack based on what we know to date, who is about to launch products and how it compares to Lithium Ion. This will need to be extended as more information is released and hence we get a chance to do more calculations. Sodium Ion Chemistry Sodium-ion batteries … Read more
Sodium-ion cells are in the very early stages of mass production, with the first commercial systems being available for purchase in 2023. Some typical characteristics of sodium-ion cells include: The table below provides an overview of some of the companies working around Sodium-ion battery production, and details of their chosen cell designs: Note that a … Read more
Many of the battery components in both sodium-ion and lithium-ion batteries are similar due to the similarities of the two technologies. This post provides a high-level overview of sodium-ion battery materials. Cathode materials Anode materials Metallic anodes are also being researched for Na-ion batteries, although these are not yet being considered for commercial applications. Electrolytes … Read more
