Fourth-generation LFP batteries pack more into each cell without changing chemistry
1+ week, 6+ day ago (505+ words) It could reduce the amount of space needed for the same amount of stored energy. Fourth-generation lithium iron phosphate batteries could enhance the utility of one of the essential clean-energy tools. The large battery systems that store electricity for later…...
Engineered bacteria may speed one of Earth's oldest ways of pulling carbon dioxide from the air
1+ week, 1+ day ago (475+ words) A slow but powerful natural climate process may be getting a high-tech boost as researchers explore whether engineered bacteria can accelerate the breakdown of rocks, potentially speeding a natural pathway that removes carbon dioxide from the atmosphere. On Aug. 28, 2026, Phys....
Sodium-ion batteries near a key EV milestone, and they may already undercut lithium on price
3+ week, 1+ day ago (524+ words) "It doesn't come with the geopolitical baggage that lithium, nickel, and cobalt do." Two trends are converging for sodium-ion batteries: their energy density is climbing toward levels long associated with lithium packs, while pricing may again be shifting in sodium's…...
New York scientists engineer a bacterium that captures air pollutant and releases battery metals
3+ week, 1+ day ago (414+ words) The research fits into a broader push to build climate solutions that generate something valuable instead Cornell scientists have modified a bacterium to accelerate the breakdown of ultramafic rock, speeding up a natural reaction that can support carbon dioxide capture....
