Sodium-Ion Battery Industrialization 2026: Where We Actually Stand
Sodium-ion batteries have been "the next big thing" since 2021. CATL launched the first commercial Na-ion cell in July 2021. Five years later, where do we actually stand? Not…

Sodium-ion batteries have been "the next big thing" since 2021. CATL launched the first commercial Na-ion cell in July 2021. Five years later, where do we actually stand? Not…
This is the 100th article on GreenEngGuide. When I started this site in May 2026, I had one goal: write technical content from someone who actually stands inside Chinese…
When a chemical plant or battery factory generates hazardous waste that can't be landfilled, the rotary kiln incinerator is often the only viable disposal route. But designing one…
Solid-state batteries have been "2-3 years away" for a decade. But in 2026, something changed: Toyota announced commercial production starting 2027, Samsung SDI began pilot-line…
The EU Battery Regulation isn't coming — it's here. By August 2025, every battery placed on the EU market needs a carbon footprint declaration. By February 2027, a full Battery…
China's Soil Pollution Prevention and Control Law (土壤污染防治法, effective January 2019) introduced mandatory self-monitoring and reporting obligations for "key soil pollution…
I've designed tank farms for chemical plants, refineries, and battery factories. The principles are the same across industries, but the consequences of getting them wrong vary…
A pressure safety valve (PSV) is the last line of defense between normal operation and catastrophic failure. When everything else fails — the control system, the operator…
Every industrial facility uses chemicals. Every chemical comes with a Safety Data Sheet (SDS). And in my experience, most facilities have a binder full of SDSs that nobody reads…
Every process plant starts as a P&ID (Piping and Instrumentation Diagram) — a 2D schematic that says what the plant does. The 3D model says where everything goes. The gap…
"Black mass" is the industry term for shredded and processed spent lithium battery material — a dark, fine powder containing a cocktail of valuable metals: lithium, cobalt,…
Slurry mixing is the first process step in electrode manufacturing — and the one where quality problems are hardest to fix downstream. A poorly mixed slurry with agglomerates,…
If there's one room in a lithium battery factory that costs more per square meter than a hospital operating room, it's the dry room. A -40°C dew point environment — where the air…
Grading and matching is the final quality gate in lithium battery manufacturing — the last step before cells are assembled into modules and packs. Get it wrong, and your battery…
After coating and calendering, the electrode sheet is a continuous ribbon of active material on metal foil — hundreds of meters long, ready to be cut into individual electrode…
Every lithium battery has an anode. For 30 years, that anode was graphite. For the next 30 years, it probably still will be — but which graphite, and mixed with what, is changing…
Electrolyte filling—the step where liquid electrolyte is injected into a sealed or semi-sealed battery cell—looks simple. A needle dispenses liquid into a cell. The cell gets…
When a lithium-ion battery reaches end of life, everyone focuses on the metals—cobalt, nickel, lithium. The electrolyte? Usually burned off during the pyrometallurgical recycling…
The cathode is 30-40% of a lithium-ion cell's cost and determines its voltage, capacity, safety characteristics, and roughly half its carbon footprint. Pick the wrong cathode…
China Watch is a weekly briefing on under-reported regulatory developments from China's environmental and battery sectors. What Happened On June 1, 2026, China's State…
