For many car patrons, their technical automotive knowledge quantities to this: they know a automobile has an engine (or motor), and they want the largest, most powerful one they will afford. Early-adopting EV patrons appear likely to be a little extra knowledgeable, and Tesla is taking the unprecedented step of giving patrons a selection between two different battery chemistries.
Tesla has reportedly been contacting Model three reservation holders in the US, and offering the option of choosing Lithium Iron Phosphate (LFP) battery cells instead of the usual Nickel Cobalt Aluminum Oxide (NCA) cells.
As InsideEVs’ Steven Loveday notes, many readers in our nook of the media world are geared up to have a lively conversation about the pros and cons of LFP versus NCA chemistries, however we shan’t go down that rabbit hole here. A 10-minute video from Cleanerwatt explains a few of the technical points.
The commerce-off being offered to Tesla patrons is a bit less vary in exchange for quicker delivery. Tesla told its reservation holders that an LFP-equipped Model 3 would have about 10 fewer miles of EPA-estimated range, but may very well be delivered much sooner.
LFP cells tend to be cheaper, and contain no nickel or cobalt, but their power density is lower. Typical knowledge is that this commerce-off makes LFP less appropriate for high-finish EVs, which have to deliver performance and range, however a good selection for decrease-priced fashions.
LFP-primarily based batteries have been the norm in the Chinese language EV trade for years. Tesla began utilizing LFP batteries at the Shanghai Gigafactory in 2020, and is now exporting made-in-China Model 3s with LFP cells to Europe. I have a Mannequin 3 on order. Simply received this about 10 minutes ago.

The confluence of several elements-improved expertise, production bottlenecks, expansion of the EV market to mid-value patrons-could soon carry more LFP batteries to the North American market. Final 12 months, Elon Musk said that the vitality density of LFP cells has improved sufficient that it now is smart to use them in Tesla’s decrease-priced models. Bloomberg studies that VW, Ford and Stellantis have all announced that they'll use LFP in low-cost, low-range EVs in the future.
There’s another problem with LFP-all the major producers of the material are in China. Because of the small print of a licensing settlement, Chinese cathode producers have been ready to supply LFP cheaply, whereas international companies have confronted increased costs. Nevertheless, this situation could change soon-as Bloomberg stories, the final of the three worldwide patents that management LFP manufacturing outdoors of China are due to expire in 2022.
