A method of making a lithiated silicon-based precursor material for a negative electrode material of an electrochemical cell that cycles lithium ions is provided. An admixture comprising a plurality of lithium particles and a plurality of silicon particles is briquetted by applying pressure of greater than or equal to about 10 MPa and applying heat at a temperature of less than or equal to about 180° C. to form a precursor briquette. The briquette has lithium particles and silicon particles distributed in a matrix and has a porosity level of less than or equal to about 60% of the total volume of the precursor briquette. The briquetting is conducted in an environment having less than or equal to about 0.002% by weight of any oxygen-bearing species or nitrogen (N.sub.2).
