A stochastic investigation of lithium deinsertion from individual 200‐nm‐sized particles of LiMn₂O₄ reveals the rate‐determining step at high overpotentials to be the transfer of the cation across the particle–electrolyte interface. Measurement of the (electro)chemical behavior of the spinel is undertaken without forming a conductive composite electrode. The kinetics of the interfacial ion transfer defines a theoretical upper limit for the discharge rates of batteries using LiMn₂O₄ in an aqueous environment.

LiMn2O4颗粒的锂离子转移动力学

对LiMn ₂ O _4的单个200 nm大小的颗粒中的锂脱嵌的随机研究表明，在高超电势下，决定速率的步骤是阳离子在颗粒-电解质界面上的转移。在不形成导电复合电极的情况下进行尖晶石的（电）化学行为的测量。界面离子转移的动力学定义了在水环境中使用LiMn ₂ O ₄的电池放电速率的理论上限。
