Semi-Solid State Battery Calendering and Porosity Control
At Horizon Power, I spend a lot of time on the electrode production floor. Calendering is one of the steps that separates a good semi-solid state battery f…
Semi-Solid State Battery Pouch Heat Sealing and Degassing
At Horizon Power we build semi-solid state cells in both prismatic and pouch formats, and after years on the pilot line I can say the pouch route lives or…
Semi-Solid State Battery Current Collector Foil Selection
Every electrode in a lithium battery does two jobs: store lithium, and hand the electron to the outside circuit. The first job gets all the attention in ce…
Semi-Solid State Battery Electrode Slurry Mixing and
When engineers talk about semi-solid state batteries, most of the attention goes to energy density numbers and the promise of safer chemistry. In my work a…
Semi-Solid State Battery Low Temperature Performance
Every fleet manager who runs equipment in a northern climate asks me the same question before they approve a new chemistry: how does it behave when the tem…
Semi-Solid State Battery Pilot Line Cost Modeling
When a customer asks me how much a semi-solid state battery will cost at volume, I tell them the honest number only exists after you have built the pilot l…
Semi-Solid State Battery Cell Traceability and Batch Records
When a fleet operator reports a semi-solid state battery that swelled after 400 cycles, the first question is never “what failed”. It is “which batch, whic…
Semi-Solid State Battery for Portable Military Electronics
As a senior lithium battery engineer I have spent the last decade building power systems for equipment that cannot fail in the field. Portable military ele…
Semi-Solid State Battery for Smart Locks and Access Control
Most smart locks still ship with commodity cylindrical cells that were never designed for a door. At Horizon Power I have tested dozens of access-control b…
Semi-Solid State Battery Sulfide Electrolyte Handling Safety
When I first moved from liquid lithium-ion lines to a sulfide-based semi-solid state battery pilot line, the biggest adjustment was not the electrochemistr…
