A method and system for producing highly activated silicate material, wherein the silicate source material is provided for reaction with a reforming agent in a reforming process. The reforming process is a hydrothermal process and/or a high temperature silicate reforming (HTSR) process. A heat source heats reaction materials to a reaction temperature in the presence of a reaction medium. For the hydrothermal reaction process, the reaction medium and heat source are an exhausted steam that is a byproduct of another industrial process. For the HTSR process, the silicate source material and the heat source are a molten slag byproduct from another industrial process.

The present disclosure relates to an anode active material for a rechargeable lithium battery including calcium silicate, a method for preparing the same, and a rechargeable lithium battery including the same. According to the present disclosure, it is possible to improve the initial efficiency of a rechargeable lithium battery by providing an anode active material for the rechargeable lithium battery that does not react with lithium and to provide a rechargeable lithium battery with improved charge/discharge life characteristics by increasing the sizes of internal pores.
