NIO has officially launched today an all-new 75 kWh standard-range, hybrid-cell battery pack, which replaces the previous 70 kWh battery option (NCM). Orders are accepted now, while customer deliveries will start in November.
The "hybrid-cell" is just a marketing name, as there are no hybrid cells - the battery pack is a hybrid that consists of two different lithium-ion battery cell chemistries: NCM (nickel:cobalt:manganese) and LFP (lithium iron phosphate). The ratio of NCM/LFP was not disclosed (we guess that it might be simply 1:1 or 2:1).
The purpose of combining the two types is to enhance the overall parameters of the battery. The NCM cells are known for their high energy density, while the LFP is the least expensive.
The new hybrid-cell battery also has no battery modules as NIO applied its new-generation cell-to-pack (CTP) technology. That simplifies production, reduces costs and additionally improves energy density.
The results are pretty interesting, as the company is now able to offer a 75 kWh at a price of the outgoing 70 kWh version, which increases the range of ES8, ES6 and EC6 cars by at least several percent.
NIO standard-range, hybrid-cell battery pack stats:
- 75 kWh (5 kWh or 7% more than 70 kWh previously)
- battery cell chemistry: NCM and LFP
- NCM/LFP ration: N/A
- cell-to-pack (CTP) technology (no modules)
- simplified manufacturing and assembly by 10%
- increased volume utilization by 5%
- increased energy density by 14% to 142 Wh/kg
One might ask why not...
