I am curious about the choice of lithium-ion vs. something like lithium-iron-phosphate (LFP) battery chemistry.
Obviously, there is a good reason for Tesla and Panasonic not to have chosen LFP, does anyone know why? I know the energy density is lower, but are there other reasons?
- swypych 12y agoI would suspect safety is probably the driving force here, especially considering the capacity of these batteries. https://suite.io/mike-dehaan/4bfn2v4 https://suite.io/mike-dehaan/4bfn2v4 http://www.umanitoba.ca/outreach/conferences/phev2007/PHEV2007/proceedings/PluginHwy_PHEV2007_Session1_Guerfi.pdf http://www.umanitoba.ca/outreach/conferences/phev2007/PHEV20...
- seanflyon 12y agoI assume cost per watt-hour is the dominant factor.
- TD-Linux 12y agoLithium iron phosphate has much lower energy density (energy per weight). This is the most important factor in the choice of battery, along with the cost per energy. LFP's advantage is in power density, which is not an issue with the size of pack that Tesla is using.
