Overview

 

Lithium-ion Battery

For the commercialization of electric-powered vehicles, Nissan has been developing lithium-ion batteries - one of the key technologies - since 1992 with focus on reducing the size while increasing power and capacity. In April 2007, Nissan established Automotive Energy Supply Corporation in partnership with NEC Corporation and NEC Tokin Corporation for mass production.

Features


  1. High power
    Lithium-ion batteries generate higher electric voltage than lead-acid batteries and nickel metal hydride batteries, allowing for higher power output.
  2. High capacity
    Lithium with higher energy density realizes higher capacity battery.

Lithium-ion Technology

Nissan maximizes the performance and safety of lithium-ion batteries by the following three technologies:

  1. Laminated structure
    Laminated structure having superior cooling efficiency, keeps temperatures from rising even with twice energy density, and prevents uncontrolled discharge.


  2. Manganese type cathode material
    Using manganese type electrode material with stable crystal structure prevents thermal decomposition and heat generation to ensure power output.

  3. Cell control
    The battery is designed to control the charge status of each cell in the pack individually and consistently assure stable performance. When an abnormal condition is detected, it shuts down the individual circuit for safety.
