The popular discussion of EVs tends to center on range, and this has led battery makers to focus on increasing energy density—some would say, at the expense of other equally important attributes such as longevity and safety. Chinese EV giant BYD has introduced a new Blade Battery, which is designed to “bring battery safety back… Read more »

The battery that breathes—Freudenberg’s pressure compensation system
EV batteries require pressure compensation both under normal operation and during emergency ventilation. Freudenberg Sealing Technologies’ DIAvent component combines these two functions into a single design, which will be used in the ABT e-Caddy and ABT e-Transporter, two Volkswagen vans that are popular in Europe and Mexico. To reduce battery weight and size, ABT uses… Read more »
LiTDI: An electrolyte additive for extended battery life and fast charging
Sponsored by Arkema With the electric vehicle market driving a surge in demand for lithium-ion batteries, research is intensifying to develop new electrolytes that not only ensure battery performance, lifetime, and safety, but also enable high-energy anode materials, such as silicon, and cathode materials, such as NMC 811. High purity electrolyte components are crucial to… Read more »
Voltabox to supply battery systems to e-troFit for diesel bus conversions
Industrial EV battery provider Voltabox will provide battery systems to retrofitting company e-troFit for the conversion of diesel buses to electric. Voltabox began providing battery systems to e-troFit in 2019. The two companies recently entered into a long-term agreement. e-troFit’s Conversion Kit 1 contains a modular Voltabox battery system consisting of prismatic cells based on… Read more »
Here’s why Tesla transitioned to a semi-custom power module design in Model 3 inverter
A closer look at semiconductor packaging considerations in EVs One of the most critical decisions to be made at the earliest stage of designing a new power converter concerns the packages used for the semiconductors, as pretty much every other aspect of the design hinges on their physical form. This is especially true for the main… Read more »
Enevate says its silicon-dominant anode technology is ready for EV production
Q&A with Enevate’s Founder and CTO Dr. Benjamin Park Introducing silicon into automotive-grade lithium-ion cells has been a major topic in the EV industry in the past decade. Silicon is widely considered to be the next big thing in anode technology, because it has a theoretical charge capacity ten times higher than that of typical graphite anodes…. Read more »
MIT team develops novel solid electrolytes and pure lithium anodes
New research from MIT could lead to batteries that pack more power per pound and last longer. A new paper co-authored by Yuming Chen and Ziqiang Wang at MIT explores the idea of using pure lithium as the battery’s anode. The design is part of a concept for developing safe solid-state batteries by dispensing with… Read more »
Second-life batteries used to charge buses in German pilot
The Volkswagen Group has partnered with MAN Truck & Bus on a pilot project that uses second-life batteries as stationary storage to support the charging of electric buses. At the bus depot of local transit operator VHH in the Bergedorf quarter of Hamburg, 50 battery packs, which were previously installed in VW Passat GTE plug-in… Read more »
