From atilley at unf.edu Tue Apr 9 10:58:23 2024 From: atilley at unf.edu (Tilley, Al) Date: Tue, 9 Apr 2024 14:58:23 +0000 Subject: [GWSG] Antarctic heat; the LFP battery Message-ID: 1. The Antarctic is experiencing a series of unprecedented rises in temperature. If those continue past August we will have entered a new and dangerous state of the climate. The rate of sea level rise will increase. Another effect of the rise is to diminish the algae which grow around and under the floating ice shelves. They are food for the krill, which deposit their bodies and the CO2 they carry on the ocean floor. The un-sequestered CO2 will now remain in the air, and the animals who eat the krill will decline as their food supply diminishes. Our climate models have been based on slender data from the Antarctic already and now may require revision if Antarctica continues to surprise us. https://www.theguardian.com/environment/2024/apr/06/simply-mind-boggling-world-record-temperature-jump-in-antarctic-raises-fears-of-catastrophe 2. General Motors is in talks with Chinese battery manufacturer CATL to build plants in the US or Mexico to produce their LFP (lithium iron phosphate) battery. Ford has already announced a $3.5 billion investment in a similar plant in Michigan. The LFP battery is cheaper, safer, and much longer lasting than current lithium batteries. LFP batteries use no cobalt or other rare materials. https://electrek.co/2024/03/28/gm-catl-in-talks-cheaper-lfp-battery-tech-joint-plant/ CATL has announced that they will manufacture an LFP battery which will last for almost a million miles and carries a 15-year warranty. The battery is intended for commercial vehicles such as buses and trucks. https://electrek.co/2024/04/03/catl-launches-new-ev-battery-last-1-million-miles-15-yrs/ -------------- next part -------------- An HTML attachment was scrubbed...
