NEGATIVE ELECTRODE FOR LITHIUM-ION SECONDARY BATTERY AND BATTERY WITH USE OF SUCH ELECTRODE Russian patent published in 2013 - IPC H01M4/13 H01M4/66 

FIELD: electricity.

SUBSTANCE: invention suggests negative electrode for lithium-ion secondary battery that includes conducting substrate, a layer for active material of negative electrode that contains active material that is capable to absorb and desorb lithium ions and conducting element having less elastic modulus than elastic modulus of conducting substrate. At that at least part of active material for negative electrode is connected to conducting substrate through conducting element that contains conducting chained carbon material that has less elastic modulus than elastic modulus of conducting substrate. Lithium-ion secondary battery with such negative electrode is suggested.

EFFECT: preventing separation of active material during charge and discharge cycles, improving cyclic characteristics of lithium-ion battery charge and discharge due to removal of mechanical stress occurring at change of volume by use of conductive material with chain structure.
