Lithium Battery for Floor Scrubbers and Cleaning Robots
Walk into any distribution center at 6 a.m. and the floor scrubbers are already running. What most fleet managers do not realize is that the battery, not t…
Home Energy Storage Fire Safety and Detector Placement
I am Karl Huang, Senior Lithium Battery Engineer at Horizon Power, and over the last nine years I have commissioned, audited, and repaired hundreds of resi…
Battery Solution for Ski Lifts and Aerial Ropeways
Most operators assume the public grid is the only thing keeping a detachable chairlift or gondola moving. In my field work at Horizon Power, I have stood a…
Home Energy Storage Inverter Selection for Legacy Panels
When a homeowner calls me about adding home energy storage to a rooftop array that went up between 2009 and 2017, the panels are almost never the problem….
Battery Solution for Airfield Ground Lighting
I have spent most of the past decade building lithium packs that must work when nobody is watching. Airfield ground lighting is the hardest version of that…
Sodium-Ion Battery Second Life and Repurposing
I have spent fifteen years testing lithium packs, and most of what I believed about retired batteries had to be rewritten the first time I graded a batch o…
Semi-Solid State Battery Internal Pressure Sensing
Pressure is the one signal that tells you what is actually happening inside a sealed cell. Voltage and temperature are averages taken at the terminals and…
Sodium-Ion Battery Calendering and Porosity Control
Sodium-ion cells ask the calender to do something lithium-ion never asked of it. The hard carbon anode stores most of its sodium in pores rather than betwe…
Semi-Solid State Battery Dry Electrode Processing
Every solvent we remove from a factory is a problem we no longer have to solve. That is the honest argument for dry electrode processing, and on semi-solid…
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…
