▎ 摘　　要

NOVELTY - An electrochemical cell comprises an active anode metal electrochemically deposited on a host material functionalized with one or more electrochemically active groups, where the active anode metal comprises an electrochemically active surface, an electrolyte, a solid electrolyte interphase layer having a thickness of 50-200 nm and arranged on the electrochemically active surface of the active anode metal and comprising a metal salt (S1) which is a reaction product (P1) of an electrochemical decomposition of at least a portion of the electrochemically active groups, where a metal cation in the metal salt (S1) and the active anode metal comprise the same metal, and the electrochemical cell is stable for about 200-600 plating/stripping cycles at (-60degrees Celsius)-45degrees Celsius. USE - Electrochemical cell used for battery (claimed). ADVANTAGE - The electrochemical cell provides battery with excellent performance under low-temperature and high-rate-charging conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a battery, which comprises the electrochemical cell, and a cathode material.
