Oily wastewater is one of those treatment problems where the physics hasn't changed in 50 years, but plants still get it wrong with surprising regularity. The principles—gravity…
Every Monday, China Watch brings you one under-the-radar regulatory or industry development from China that will matter to your business in 3-6 months. Because by the time the…
After coating and drying, your electrode is a porous, fragile film of active material particles loosely bonded to a metal foil. It has about 40-60% porosity, poor electrical…
Every lithium battery cell—whether it powers a power tool, an EV, or a grid storage system—starts with the same two materials: anode and cathode sheets with separator in between.…
If you've ever stood in front of a vendor's quote comparing a $45,000 shell & tube exchanger against a $28,000 plate heat exchanger and wondered if the cheaper option will…
If you're specifying a VOC abatement system for a chemical plant, battery factory, or coating line, the RTO-vs-RCO decision is one of the first forks in the road. Pick wrong, and…
After setting up more than 40 Plant 3D projects for industrial facilities — from battery material plants to wastewater treatment stations — I've learned one thing the hard way:…
Every industrial software vendor has been selling "digital twins" for five years now. Most of what they're selling is a 3D CAD model with some real-time data tags overlaid —…
If you ask a fire protection engineer what keeps them up at night in 2026, the answer won't be chemical plants or oil refineries. It'll be battery energy storage systems. The…
A lithium battery factory produces 500,000 cells per day. Each cell goes through mixing, coating, calendaring, slitting, winding/stacking, electrolyte filling, formation, and…
!Battery manufacturing facility(https://images.unsplash.com/photo-1620714223084-8fcacc6dfd8d?w=800) China's lithium battery manufacturing capacity hit roughly 1,200 GWh in 2025 —…
In January 2026, five Chinese government agencies jointly released a document that will reshape manufacturing over the next decade. The "Guiding Opinions on the Construction of…
When you walk into a lithium battery factory for the first time, the scale is what hits you. Electrode coating lines 60-80 meters long. Formation rooms with thousands of cells…
I've prepared environmental impact assessments for chemical plants, steel mills, and water treatment facilities. When I looked at my first battery factory EIA, I expected it to be…
The battery industry has a fire problem. Not in the cells — in the factories that make them. A lithium battery factory contains all the ingredients for a fire: flammable solvents,…
NMP — N-Methyl-2-pyrrolidone — is the solvent used in cathode electrode manufacturing. It dissolves PVDF binder, creates a coatable slurry, and then evaporates in the dryer. At…
After the slurry is mixed, it goes to the coating line — a machine the length of a tennis court that spreads a thin layer of electrode material onto aluminum or copper foil with…
When people talk about lithium battery manufacturing, they usually focus on the supply chain — lithium mining, cobalt sourcing, graphite processing. But there's an environmental…
Six months ago, I moved from designing wastewater treatment plants to working in lithium battery manufacturing. On my first day, the production manager walked me to the slurry…
