Amperesand’s solid-state transformers could help break electric grid bottlenecks
Here’s a story we hear often: a CPO or fleet operator wants to deploy a large-scale EV charging facility, but the project is delayed for months or years because the local utility is waiting for the necessary transformers to be delivered. (Two out of two subjects of infrastructure articles in our current print issue—XCharge’s Alex… Read more »
Saint-Gobain invests in solid-state battery firm ION Storage Systems
NOVA, the partnership and venture capital branch of building materials company Saint-Gobain, has invested in solid-state lithium metal battery company ION Storage Systems to expand their battery technology collaboration. The companies are working to establish US manufacturing of ceramic material for large-scale solid-state battery electrolyte manufacturing.
