Why Electric Vehicles Choose to Use NCM Cells ?

Time:2023-05-15 Views:1

NCM cells and LiFePO4 cells are two common lithium-ion battery technologies widely used in the field of electric vehicles. Here is an explanation and analysis of their advantages and disadvantages, as well as why electric vehicles choose to use NCM cells.


Advantages of NCM cells:

High energy density: NCM cells have a higher energy density, allowing them to store more energy and provide longer range for electric vehicles.

High power output: NCM cells can deliver high power output, resulting in better acceleration and performance during uphill climbs.

Cost-effectiveness: NCM cells have relatively lower manufacturing costs compared to other lithium-ion battery technologies, making them favorable for commercialization of electric vehicles.

Wide temperature range: NCM cells can operate within a broader temperature range, making them suitable for various climate conditions.

Disadvantages of NCM cells:

Safety risks: NCM cells may pose safety hazards under extreme conditions such as overcharging, overdischarging, or overheating. Measures need to be taken to ensure battery stability and safety.

Relatively shorter lifespan: NCM cells have a shorter cycle life compared to some other battery technologies, requiring more frequent replacement or maintenance.


Why electric vehicles choose to use NCM cells ?

High energy density and power output: The high energy density and power output of NCM cells provide electric vehicles with longer range and better performance, resulting in an enhanced driving experience.

Cost-effectiveness: The relatively lower manufacturing costs of NCM cells contribute to reducing the price of electric vehicles, thereby increasing their market competitiveness.

Technological maturity: NCM cells are a mature technology widely applied in the electric vehicle industry. The supply chain and manufacturing processes are relatively mature, facilitating production and scaling.

Adjustability: NCM cells can be adjusted by varying the ratios of nickel, cobalt, and manganese to balance energy density, power output, and cycle life, meeting the requirements of different electric vehicle applications.

In summary, electric vehicles choose to use NCM cells due to their high energy density, high power output, cost-effectiveness, and technological maturity, despite the safety risks and relatively shorter lifespan. NCM cells offer advantages that enhance the driving range, performance, and market competitiveness of electric vehicles.
