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…
Semi-Solid State Battery Thermal Interface Materials
Karl Huang here, senior lithium battery engineer. When my team moved from conventional lithium battery packs to semi-solid state battery modules, the therm…
Semi-Solid State Battery Post-Mortem Failure Analysis
When a semi-solid state battery comes back from the field, the most expensive mistake is calling it dead, scrapping it, and moving on. Every returned cell…
Semi-Solid State Battery Peak Power for Performance EVs
In eleven years of specifying lithium battery packs for vehicle programmes, the performance-car brief is still the one that surprises people. Nobody asks m…
Semi-Solid State Battery Interface Wetting and Impedance
In fifteen years of building lithium cells I have watched more semi-solid state battery programs fail on a step nobody photographs than on chemistry itself…
Semi-Solid State Battery Formation Cycling and Yield
Formation is the step where a stack of coated electrodes and a semi-solid electrolyte stops being a set of parts and becomes a battery. Nearly everything I…
Semi-Solid State Battery Silicon Anode Blending
When a customer asks us to raise the energy density of a semi-solid state battery without changing the cell footprint, the anode is where the leverage sits…
