Abstract:
The present invention generally relates to materials for electrochemical cells, e.g., for use in batteries such as lithi- um-ion batteries, and other applications. For example, certain embodiments of the present invention provide a positive electroac- tive material, which may have a core-shell structure. The material, in certain embodiments, has the formula (Li 1+a [Ni q M r Co 1-q-r]  O 2 ) x .(Li 1−a [Ni s Mn t CO 1-s-t ]O 2 ) 1-x , where M may be Mn and/or Al. In some cases, the first portion may represent the core, while the second portion may represent the shell in a core-shell particle. In certain embodiments, x is a numerical value inclusively ranging from 0.70 to 0.95, a is a numerical value inclusively ranging from 0.01 to 0.0 7, q is a numerical value inclusively ranging from 0.80 to 0.96, r is a numerical value inclusively ranging from 0.01 to 0.10, s is a numerical value inclusively ranging from 0.34 to 0.70, t is a numerical IN value inclusively ranging from 0.20 to 0.40. Additionally, some embodiments are directed to methods of forming particles, such as core- shell particles, by forming the core and the shell within the same reactor, and/or by altering the pH to produce the core and the shell, and/or by altering the stirring rate to produce the core and the shell, and/or by altering the feed rate to produce the core and the shell. in In some embodiments, by controlling reaction parameters such as these, the materials may have a surprisingly narrow, homogeneous particle size distribution, e.g., as measured by Span or other suitable techniques.
