Questions and Answers

Q  What can affect the stability of NMC when cycled to high voltages?

A   The stability of NMC is affected by 

  1. structural transformation from layered to spinel and/or rock-salt phases
  2. mechanical damage such as crack formation in active particles
  3. parasitic reactions between cathode and the electrolyte 
  4. migration, segregation and dissolution of transition metals 

Q  Why do single crystals matter?

A  The benefits of single crystal cathode materials:

  1. Coatings on single crystal particles remain intact with repeated cycling 
  2. less undesirable side reactions with the electrolyte
  3. long lasting and durable lithium ion battery cells
  4. high gravimetric energy density and high volumetric energy

Q  Why single crystal NMC is trending in EV industry?

A  As battery is the most expensive component of EV, not only does battery health affect the vehicle’s residual value, but it also has a direct impact on the maximum usable range over time. The cycling life of battery using traditional NMC is usually shorten in an extreme weather condition. Single crystal NMC with better structure stability is a promising cathode material for long life time EV applications. The Tesla researchers patented a single crystal NMC which can be cycled for more than 4000 cycles at 40 °C.
