Phase change materials
Phase change materials offer intriguing possibilities in the thermal management of EV powertrains as Nick Flaherty explains
Phase-change materials (PCMs) are known for their superior latent heat capacity, acting as heat absorbers without notable temperature increases. This property can be used in many different ways throughout the powertrain of e-mobility systems, from enhancing the heat transfer in the power electronics to cooling the entire battery pack Read more…
Battery coatings
Peter Donaldson finds complex challenges within the development of coatings for battery applications
Coatings play a crucial role in battery cells, modules and packs. Evolving continuously, they are engineered to enhance performance, safety, reliability and longevity in these complex, high value electrochemical systems. While the active materials that constitute the core components of cells – the anode and cathode – are applied to their substrates as coatings, this article will focus mainly on the supporting players.

LFP cells charge in six minutes
DESTEN has developed the first Lithium Iron Phosphate (LFP) cell that can charge in just six minutes at 6 C writes Nick Flaherty. The 160 Wh/kg pouch cell developed by DESTEN is capable of charging from 20% to 80% SOC in six minutes at a charging rate of 6 C. Moreover, the LFP chemistry means the cell is intrinsically safer than lithium ion cells. Read more…
New Renault Master E-Tech electric’s WLTP range – up to 460 km
Renault has chosen two batteries optimised for capacity, size and mass, combined with in-depth work on aerodynamics and a brand-new innovative platform.
The van comes with a choice of two energy storage capacity ratings: 40 kWh and 87 kWh. These two packs are built into a single casing and designed for driving requirements in cities as much as in suburbs. And they do not hamper the vehicle’s payload capacity – which is an essential criterion in this segment. Read more…
Ascend Elements Targets 90% Reduction in EV Battery Material Carbon Footprint By 2030

Using its patented Hydro-to-Cathode® process and recycled materials, Ascend Elements can today manufacture new EV battery material (NMC 622 cathode) at a 49% reduction in carbon emissions compared to traditional cathode manufacturing processes that rely on primary materials from mining. Read more…
Tony Persson
Scania AB’s head of battery production Tony Persson explains to Rory Jackson his company’s key role in the development of electric vehicles for demanding applications
The race to electrify road vehicles is bringing with it a race to develop internal competencies in producing key e-mobility technologies, and battery packs frequently make the top of the list. As of mid-2023, around 30 battery factories were planned, being built, or already operational in the US, with around 35 in the EU and several times more in China. Read more…
In wheel motor development
YASA is working with Domin on an in-wheel motor system that weighs under 2 kg, writes Nick Flaherty. The project with Cranfield University in the UK will create a patented in-wheel motor design using YASA’s axial flux motor and Domin’s digitally controlled hydraulic active suspension. The aim is to develop a motor system that is ten times lighter than the current 12 kg motor package design. Read more…
