Sodium-Ion Battery for Desalination and Off-Grid Water
Why Desalination Is Moving Off the Grid
Over the last three years I have watched a clear shift in how small and mid-sized water plants are being built. Com…
Sodium-Ion Battery for Pipeline Cathodic Protection
As a senior lithium battery engineer at Horizon Power, I have spent the last decade shipping cells into fleets that cannot afford a quiet failure. When pip…
Sodium-Ion Battery Overdischarge Tolerance and 0V Storage
Ask any pack engineer which single failure mode keeps them awake at night and the answer is usually the same: one cell driven negative inside a series stri…
Sodium-Ion Battery for Snow Groomers and Winter Maintenance
Most fleet managers assume that any lithium battery rated for industrial use will work in a snow groomer or winter road-maintenance truck. In my experience…
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…
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…
Sodium-Ion Battery Fire Suppression and Detection Design
Fire protection for a battery room is usually specified by someone who has never watched a cell vent. I have, twice, in abuse testing, and both times the s…
Sodium-Ion Battery Water-Based Electrode Processing
Water-based electrode processing keeps coming up because it removes the most expensive and most regulated fluid on the coating line. I have run NMP and aqu…
Sodium-Ion Battery Electrolyte Salt Selection
Sodium-ion battery electrolyte salt selection is one of those decisions that looks like a purchasing detail and turns out to define cycle life, low-tempera…
Sodium-Ion Battery Presodiation and Sodium Compensation
Sodium-ion cells lose a measurable slice of their sodium inventory during the very first charge. On the production line that loss shows up as a first-cycle…
