摘要： Disclosed is an anode active material, comprising: (a) a carbonaceous material; and (b) a carbide coating layer partially or totally formed on a surface of the carbonaceous material, the carbide coating layer comprising at least one element selected from the group consisting of metals and metalloids. An anode obtained by using the anode active material and an electrochemical device comprising the anode are also disclosed. The carbonaceous material comprises a coating layer of metal-/metalloid-carbide obtained by treating it at high temperature under inert atmosphere, wherein the coating layer has increased interfacial boding force to the carbonaceous material and thus shows minimized reactivity to lithium. The carbonaceous material as anode active material can minimize the irreversible anode capacity needed for the formation of an SEI film during the first charge/discharge cycle, thereby providing high capacity, high efficiency and significantly improved anode qualities.

摘要： Disclosed is a method for preparing an electrochemical device, comprising the steps of: charging an electrochemical device using an electrode active material having a gas generation plateau potential in a charging period to an extent exceeding the plateau potential; and degassing the electrochemical device. An electrochemical device, which comprises an electrode active material having a gas generation plateau potential in a charging period, and is charged to an extent exceeding the plateau potential and then degassed, is also disclosed. Some electrode active materials provide high capacity but cannot be applied to a high-capacity battery due to the gas generation. This is because a battery using such electrode active materials should be charged to an extent exceeding the gas generation plateau potential in order to realize a high capacity. To solve the problems caused by the gas generation, the battery is charged to an extent exceeding the plateau potential, and then degassed. In other words, the problems including variations in outer shape of a battery and degradation in cycle life characteristics and C-rate characteristics of a battery can be solved. After the first cycle, the battery can be charged to an extent exceeding the plateau potential with no further gas generation, thereby providing a significant increase in capacity.

摘要： Disclosed is a pretreatment method for activating an electrode active material having a certain range of potential plateau beyond a redox potential range of a transition metal forming the electrode active material, which comprises charging the electrode active material to an extent exceeding the potential plateau at least once, so as to increase capacity of the electrode active material. Also, disclosed is an electrochemical device comprising the electrode active material activated by the pretreatment method and designed to be subjected to charge/discharge cycles at a voltage lower than the potential plateau. When the electrode active material pretreated by charging it to an extent exceeding the potential plateau is subjected to charge/discharge cycles at a lower voltage, it is possible to significantly increase the capacity of the electrode active material as compared to the capacity of the non-pretreated electrode active material charged/discharged at the same voltage. It is also possible to inhibit reactivity of an electrolyte by performing charging/discharging at a lower voltage from the charge cycle subsequent to the pretreatment.
