An electrode for a lithium secondary battery, including a surface having surface roughness of about 800 nm to about 1000 nm, and a lithium secondary battery including the same. A tool’s operational properties are measured in real-time. After the one end of the slip and packer unit is set, further displacement of the actuator expands the other end of the elements against the casing wall. Above the selection transistor is a metal bit line electrically connected to the drain region in the semiconductor substrate column. A bypass diode is typically connected in shunt across the input terminals of the converter.
