NIO is set to upgrade its entry-level Standard battery pack option in the upcoming 2024 model year cars.
As reported by CnEVPost, the current 75-kilowatt-hour dual-chemistry (LFP/NCM) Standard battery will be replaced with a new 75-kWh battery containing only LFP battery cells. This transition is expected to simplify the pack and reduce costs, as LFP battery cells are known for being one of the most cost-effective options per kilowatt-hour.

LFP vs. NCM battery chemistry
The lithium-ion battery family consists of different chemistries, distinguished by their electrode materials. LFP and high-nickel NCM or NCA branches are among the most popular options. LFP is typically the most cost-effective type, despite being less energy-dense than other variants.
Initially, NIO offered a 70-kWh all-NCM Standard battery and a 100-kWh NCM option. In late 2021, the 70-kWh NCM battery was replaced by the 75-kWh hybrid pack (LFP/NCM). The latest upgrade to an all-LFP 75-kWh pack simplifies the technology, reduces costs, and brings performance improvements.
The new battery has been optimized for algorithms, materials, and performance, increasing peak DC fast charging power from 140 kW to 170 kW and reducing 10-80% SOC charging time to 27 minutes from 30 minutes.
Aside from cost-efficiency, LFP batteries offer good cycle-life and high safety features, although they have lower energy density compared to NCM. Challenges related to cold weather performance and SOC estimation may still persist.
NIO’s shift from a hybrid to a standard single-chemistry battery solution aligns with industry trends. The company also offers a 150-kWh solid-state battery option for extended range needs, compatible with NIO’s battery swap stations.
