Semi-Solid State Battery Electrode Coating Uniformity
I have spent enough hours staring at coating gauges to say this plainly: on a semi-solid state battery line, electrode coating uniformity is where most of…
Semi-Solid State Battery Dry Room Dew Point Control
Moisture is the quietest failure driver in lithium battery manufacturing. It rarely stops a line on the day the leak starts, hides inside an electrode roll…
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 Certification and Transport Guide
I have shipped semi-solid state cells to test houses and customers on four continents, and the same conversation happens every time. A procurement team he…
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 for Medical Devices and Implants
I am Karl Huang, a senior lithium battery engineer, and the two hardest design reviews I sit through every year are not about cars or aircraft. They are a…
Semi Solid State Battery Electrolyte Formulation
I have spent the better part of a decade standing next to coating heads, dry rooms and formation
cabinets, and if there is one lesson that separates a work…
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 Cold Start Performance
I have lost count of the number of cold-chamber mornings I have spent watching a battery pack that worked perfectly at 25°C collapse into a few hundred…
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…
