Final answer:
The use of LiMn2O4 cathodes in Li-ion batteries for automobiles is true; it offers benefits over Li-CoO2, particularly in terms of stability and safety for automotive applications.
Step-by-step explanation:
The statement that Li-ion batteries used in automobiles typically use a LiMn₂O₄ cathode in place of the Li-CoO₂ cathode found in most li-ion batteries is true. LiMn₂O₄, or lithium manganese oxide, is a common cathode material used in electric vehicle batteries due to its thermal stability, safety, and cost effectiveness compared to lithium cobalt oxide (LiCoO₂). Although LiCoO₂ cathodes have a higher energy density, which is beneficial for portable electronics, the advantages of LiMn₂O₄ make it more suitable for the demanding requirements of automotive applications.
