EFFECTS OF CYCLABILITY OF C1,A1-DOPED AND Cl,Al-CODOPED SPINEL LiMn_2O_4

摘要

Up to now,the positive electrodes of the LiCoO_2 were mainly used for lithium ion batteries.They were promising for various applications such as portable electric devices,for cellular phones and notebook computers.Due to cobalt resource lacked and higher cost price confine the batteries application range.Recently,focus on larger rechargeable batteries applications such as electric scooters,electric bicycles,and electric vehicles has intensified the search for lower cost,safer and less toxic cathode material than LiCoO_2.
