Batteries are everywhere: phones, solar home kits, motorbikes, UPS units, and increasingly, electric two- and three-wheelers. When those batteries die, they don’t vanish — they become a stream of hazardous waste and a potential source of valuable materials. Setting up reliable collection and logistics for […]

Think about the millions of batteries that will reach their end of life in the coming years. Electric vehicles, laptops, power tools, and grid storage systems will generate a tidal wave of packs and cells. Disassembling those packs safely and cheaply is one of the […]

If you’re asking whether hydrometallurgical recycling can outcompete pyrometallurgical recycling at scale, the honest answer is: it depends. Hydrometallurgy generally wins on material recovery, lithium capture, and greenhouse-gas intensity, while pyrometallurgy wins on robustness and throughput for mixed, dirty feeds. The real choice for a […]

We all hear the promise: recycle batteries, save the planet. But what does that actually mean in numbers — for greenhouse gases (GHG), for water use, and for the electricity needed? And does it matter whether we’re recycling factory scrap (material that never left a […]

Batteries are the engines of our electrified future, but when they die they become a complicated puzzle. Different chemistries — NCM (nickel-cobalt-manganese), NCA (nickel-cobalt-aluminum), LFP (lithium-iron-phosphate), LMO (lithium-manganese-oxide), LCO (lithium-cobalt-oxide), and emerging chemistries — behave very differently at end of life. Some are “economically attractive” […]

As battery use surges, so does the volume of end-of-life cells. For developing countries — many of which already struggle with informal e-waste recycling and weak infrastructure — getting battery recycling right is both an urgent environmental health issue and a strategic economic opportunity. What […]

This is one of those questions that sounds simple but turns out to be delightfully complicated. On the surface, “reuse” and “recycle” seem like two steps in a neat circular loop: use a battery in a car, reuse it in a stationary system, then recycle […]

If batteries were treasure chests, urban mining would be the art of plundering cities for the gold inside them. Today’s lithium-ion batteries contain lots of valuable “treasures” — lithium, cobalt, nickel, manganese, copper, aluminum and graphite — and the world wants those back. But what […]

Batteries power our phones, laptops, electric vehicles, and grid storage. But when they die, what happens to all that valuable material inside? The answer depends a lot on two things: the chemistry inside the cells (what metals and compounds they use) and the physical format […]
