Title:
ELECTRODE, BATTERY, AND METHOD FOR MANUFACTURING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2017/073913
Kind Code:
A1
Abstract:
An electrode is provided. The electrode includes a plurality of graphite particles arranged on a current collector so as to have a plurality of pores, and a plurality of hard carbon particles mixed with the graphite particles and having weight percent determined based on charging speed and lifespan of a battery including the electrode, wherein the weight percent of the hard carbon particles is between 20% and 35%, thereby controlling charging speed and lifespan of a battery.
