POSCO Chemical to supply cathode active material to GM
POSCO Chemical, a global materials firm, has announced a binding supply agreement with GM for high-nickel cathode active material (CAM). POSCO will provide 13,770 billion Korean won (about $10 billion) worth of CAM from 2023 to 2025. POSCO plans to produce the CAM at its Gwayngyang facility in Korea. The GM and LG Energy Solution… Read more »
OneD raises $25 million in Series C funds, enters R&D agreement with GM
GM and OneD Battery Sciences will cooperate to research the possible use of OneD’s silicon nanotechnology in GM’s Ultium cells. Meanwhile, OneD has raised $25 million in Series C funding from investors including GM Ventures and Volta Energy Technologies. “Given a licensing business model and low operational costs, Series C funds will be used to… Read more »
The EV raw materials crunch: How bad, how long, how to solve it?
This article originally appeared in Issue 60: April-June 2022 Subscribe now Every new technology must overcome a series of temporary constraints on its way to widespread adoption. Since modern EVs appeared a decade ago, they’ve motored past many of these bottlenecks, (or hurdles, or roadblocks—pick your preferred metaphor). Range has increased, access to charging infrastructure has expanded,… Read more »
GM reaches agreements with two suppliers of cathode materials
LG Chem and GM have announced a binding agreement for the supply of cathode active material (CAM), a key battery material consisting of processed nickel, lithium and other materials that represents about 40% of the cost of a battery cell. LG Chem plans to supply more than 950,000 tons of CAM to GM from 2022… Read more »

GM and LG may build a second battery factory in Tennessee
If GM is going to electrify most of its lineup by 2035, it’s going to need a lot more batteries. Sending out press releases is fast and free, but building supply chains takes years and billions, so one indication of whether the automaker’s announced deadline is a serious objective or a mere aspiration will be… Read more »
GM hires EV superstar Kurt Kelty as Vice President of Batteries
It’s plain to anyone who follows the auto industry that there are pro-EV and anti-EV factions at every legacy automaker. For the last three decades, the OEMs’ interest in EVs has flapped this way and that in the winds of quarterly earnings and political shifts. Last fall, the “let’s wait awhile” contingent appeared to have… Read more »
Thermal runaway in EV battery packs: designing a mitigation strategy
Aspen Aerogels’ cutting-edge materials protect against thermal runaway Thermal runaway occurs inside a battery cell through a fault, a crash scenario or some other defect that causes the cell to release thermal energy through chemical reactions. That thermal energy increases the temperature of the cell, the increased temperature drives faster kinetics, and more heat is… Read more »
