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 for Electric Aviation
What Is a Semi-Solid State Battery and Why Aviation Teams Are Specifying It Now
Across the last eighteen months of pilot programs at Horizon Power, one che…
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…
Semi-Solid State Battery for High Altitude Platforms
I have spent the last four years building lithium battery packs for aircraft that never land. Not passenger jets — high altitude platform stations (HAPS):…
Semi-Solid State Battery Testing for EV Packs: High-Voltage
I have spent the last four years running validation campaigns on semi-solid state cells that were destined for electric vehicle traction packs, and the sin…
Semi-Solid State Battery Design for Storage: Eight-Hour
I have spent the better part of the last six years specifying packs that never move. That sounds boring until you realise that a stationary asset has to ea…
