Solid-state batteries (SSBs) offer several potential advantages over current lithium-ion batteries, including improved safety and faster charging. However, SSBs suffer from a problem that limits their durability. When lithium ions are inserted into or extracted from the electrodes, the crystalline structure of the material changes, making the electrode expand or shrink. These repeated changes in… Read more »

Nouveau Monde Graphite, Panasonic and Mitsui to develop graphite project in Québec
Nouveau Monde Graphite, Mitsui and Panasonic Energy have entered into a framework agreement to enable the next development steps of NMG’s ore-to-battery-market integrated graphite project in Québec. The deal includes a multi-year offtake agreement between NMG and Panasonic Energy for a significant portion of NMG’s active anode material. Also, an investment of US$50 million from… Read more »
Advanced Thermal Barriers: How To Transform Your Thermal Runaway Mitigation Strategy
Battery engineers face the challenge of maximizing a vehicle’s performance while optimizing thermal runaway propagation protection. In this webinar, we will explore the role of compression pads and cell-to-cell barriers in managing mechanical and thermal energy inside modules and/or packs. Attendees will develop an understanding of possible solutions, including foams, fibers, foils, and aerogels. We… Read more »
Power electronics thermal limits and how to not exceed them
To someone who isn’t involved in power electronics design, it might seem unreal that the amount of power a component can handle depends more on how effectively waste heat can be removed from it than it does on the specific electrical ratings. Sure, the voltage and current ratings are important (especially the voltage rating), but… Read more »
The advantages and limitations of wire bonding in EV applications
Sponsored by Kulicke & Soffa By: Peter Klaerner, senior manager for Wedge Bond Systems Engineering,Kulicke & Soffa Wire and ribbon bonding have traditionally been the methods of choice for creating reliable interconnects in the electronics industry. The progress in electric vehicle production has created the need for better, more reliable interconnects that can be scaled… Read more »
Umicore and Idemitsu Kosan team up to develop cathode material integrated with solid electrolyte
Umicore, a materials technology and recycling company, and oil company Idemitsu Kosan have reached an agreement to co-develop catholyte materials, which integrate cathode active materials (CAM) with solid electrolytes, for all-solid-state battery applications. Since Umicore began work on CAMs for solid-state batteries in 2017, it has established some patents in the area. “Based on more… Read more »
All 50 states, DC and Puerto Rico have submitted plans for national EV charging network
The National Electric Vehicle Infrastructure (NEVI) Formula Program, part of the Bipartisan Infrastructure Law (BIL) requires each state and territory to submit an EV Infrastructure Deployment Plan (EVIDP) in order to qualify for its share of the first round of the $5 billion of infrastructure formula funding (IFF) that will be made available over 5… Read more »
Researchers find additive can limit dendrite growth
A research team led by Dr. Hongyi Li and Dr. Tetsu Ichitsubo, both of Tohoku University in Japan, found that a multivalent cation additive can limit dendrite growth in rechargeable batteries by modifying the solvation structures of lithium or sodium ions in electrolyte. In an article published in Cell Reports Physical Science, the researchers say:… Read more »
