NIO will adopt LFP batteries to cut costs

Currently NIO sells its electric cars with 70 and 100 kWh battery packs, both options are made with NCM 811 battery cells supplied by CATL.

However, to cut costs and increase production before this year ends, the Chinese automaker will start using the cobalt-free chemistry LFP (LiFePO4) for its entry level battery options.

Moreover, the entry level battery option will have its capacity increased from 70 to 75 kWh.


The LFP battery cells will be supplied by CATL and already have an estimated kWh cost way below 100 euros (80 euros). Therefore, it’s only a matter of time until electric cars compete with ICE (Internal Combustion Engine) cars in price and availability.


The latest developments of silicon anodes and CTP (cell-to-pack) technology allow modern LFP battery packs to surpass 200 Wh/kg, which means great energy and power density for very low cost.


Anyway, it’s strange that right now only Chinese battery cell makers are developing cobalt-free batteries, all others are still focused only on NCM, NCA and NCMA.

COBRA, the European project to develop cobalt-free batteries will adopt LNMO as its chemistry, but this project is still far from delivering a mass-produced battery.

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

Great! Thanks Pedro.

I have trouble believing the energy density of 200 Wh/kg on the pack level for LFP any time soon. (at least with comparable longevity, cycle life, cost and power density as current LFP)

Teslas current high-energy packs are at 150 Wh/kg at the moment.

A 200 Wh/kg LFP packs would make a large portion of Tesla’s Battery Day development announcements irrelevant. Somehow, I doubt that they are so out-of-touch with reality.

Pedro I am wondering how battery pack energy density will be calculated on the new Williams & Italdesign EV platform. From what I have seen it doesn’t have a traditional battery pack housing. Instead it has a plate with modules on top of it that bolts to the car (essentially the sides of the battery pack and the top cover are integrated into the vehicle structure).
