Studies of morphology, nature of the surface compounds, and electrochemical performance of these materials were made by SEM, XPS, and electrochemical methods. Two fundamental factors that crucially &nbsp;improve cycling of silicon: preparing of carbon coating that able to effectively oppose to the pressure which generated by swelling lithium-silicon alloy and removing of the side processes of lithium reactivity with native layers of oxide and silanol groups, humidity surface and hydrogen groups in the silicon structure have been proposed. Carbon-coated nanosilicon has revealed the reversible capacity equal 2029 mAh/g, first cycle efficiency 81.3 % and capacity retention 91.6 % after 50 cycles in the mode: cc/cv (C/2, 5 mV, C/200), cc(C/2, 1.0 V).</p&gt;}, number={15}, journal={Поверхня}, author={Kuksenko, S.
