Sion Power’s experimental lithium metal cells deliver 2,500 cycles

Sion Power says one of its multilayer lithium metal pouch cells has performed for over 2,500 cycles, retaining 70% of its initial capacity. The cell was charged for 180 minutes at the C/3 rate and completely discharged in 45 minutes at the 4C/3 rate. The experimental cell is part of Sion Power’s Licerion product line…. Read more »

New Cryo-EM battery research tool produces image of SEI layer on lithium metal anode

Scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have used cryogenic electron microscopy, or cryo-EM, to produce high-resolution images of the solid-electrolyte interphase (SEI) layer that forms on lithium metal anodes in an approach that may improve lithium metal battery design. The scientists developed a way of collecting the SEI… Read more »
