Semi-Solid State Battery Second Life and Repurposing
As a senior lithium battery engineer at Horizon Power, I have spent the last decade watching the same pattern repeat across every new chemistry we ship. Th…
Semi-Solid State Battery Cell Grading and Binning
Most pack failures I have investigated on the bench were not caused by a bad cell chemistry. They were caused by good cells that were simply not alike. Whe…
Semi-Solid State Battery IP Landscape: A Buyer Field Guide
Semi-solid state batteries have crossed the line from conference slides to production lines. As a senior lithium battery engineer, I have spent the last fe…
Semi-Solid State Battery Module Interconnect and Fusing
I have spent the better part of a decade on the production floor and in the test lab at Horizon Power, and if there is one step where a promising semi-soli…
Semi-Solid State Battery Internal Pressure Sensing
Pressure is the one signal that tells you what is actually happening inside a sealed cell. Voltage and temperature are averages taken at the terminals and…
Semi-Solid State Battery Dry Electrode Processing
Every solvent we remove from a factory is a problem we no longer have to solve. That is the honest argument for dry electrode processing, and on semi-solid…
Semi-Solid State Battery Vent and CID Design
Most semi-solid state battery programs I review treat the vent as an afterthought, a hole the mechanical team adds after the chemistry is locked. That orde…
Semi-Solid State Battery Helium Leak and Insulation
I have rejected more semi-solid state battery lots over seal leaks and insulation failures than over capacity shortfalls. Capacity fades slowly and predict…
Semi-Solid State Battery Moisture and Contamination Control
Most of the semi-solid state battery failures I have been asked to autopsy in the last four years were not caused by a bad chemistry. They were caused by w…
Semi-Solid State Battery Tab Welding and Joint Design
After cell chemistry, nothing limits what a semi-solid state battery can deliver like its tab joints. I have watched packs built from excellent cells fail…
