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 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…
Anode-Free Semi-Solid State Battery Cells: A Design Guide
An anode-free cell is the most honest test of an electrolyte. You start with a bare copper current collector, put every milligram of lithium in the cathode…
Semi-Solid State Battery Degradation Mechanisms Explained
I have spent the last four years pulling semi-solid cells apart after they failed. Not the dramatic failures
thermal runaway, venting, fire but the quiet o…
Semi-Solid State Battery Cell Formatting and Stack Pressure
I have spent most of my career on the manufacturing side of lithium cells, and if there is one lesson the last three years have hammered home, it is this:…
Semi-Solid State Battery Fast Charge Capability and Limits
Pulling 4C out of a semi-solid state pack sounds like a spec sheet triumph until you watch a thin slice of anode under a reference electrode and see lithiu…
Semi-Solid State Battery Integration for Storage
I am Karl Huang, a senior lithium battery engineer, and over the last few years I have spent more time arguing about bolts, Belleville washers and torque s…
