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 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 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…
Sodium-Ion Battery for Electric Boats and Ferries
Sodium-ion battery packs have crossed the line from laboratory curiosity to a genuine engineering option for short-route electric passenger vessels. Naval…
Sodium-Ion Battery Hard Carbon Anode Explained
If you have been evaluating a sodium-ion battery for stationary storage, low-temperature equipment, or a cost-sensitive fleet application, you have probabl…
Sodium-Ion Battery Low Temperature Discharge Behavior
Every winter I get the same call from integrators in Harbin, Kazakhstan, and the Canadian prairies: their lithium iron phosphate packs lose so much usable…
Sodium-Ion Battery for Residential Solar Self-Consumption
I have spent the last decade specifying cells for UAV packs, telecom backup strings and, more recently, for the garage wall. In the last three years the q…
Sodium-Ion Battery Hard Carbon Anode
As Karl Huang, Senior Lithium Battery Engineer at Horizon Power, I get asked one question more than any other about sodium-ion technology: “If sodium is so…
