AB  - Lithium diffusion in LiMn(2)O(4) pellets is studied by means of isotope exchange 
      and Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS). A (6)Li-enriched 
      film deposited by Pulsed Laser Deposition (PLD) on a dense LiMn(2)O(4) pellet 
      with natural abundance of lithium isotopes is used to study the tracer diffusion 
      of lithium. The measured profiles are analyzed by numerical models describing the 
      (6)Li tracer diffusion from the film into the pellet. Experiments in the Harrison 
      type B regime of diffusion kinetics allow for the distinction and simultaneous 
      determination of bulk and grain boundary diffusion coefficients. Changing the 
      experimental conditions to reach Harrison type A behavior yields effective 
      diffusion coefficients for lithium tracer diffusion in LiMn(2)O(4). Activation 
      energies for bulk and grain boundary diffusion were obtained from experiments at 
      different temperatures. Our values are critically compared to previous studies.
