<Mean Pore Diameter>
The mean pore diameter of the LCO or LTO sintered plate was measured by a mercury intrusion method using a mercury porosimeter (Autopore IV 9510, manufactured by Shimadzu Corporation).
<Battery Capacity>
The battery capacity was measured by the following procedures. That is, the battery was charged at a constant voltage of 2.7 V and then discharged at a discharge rate of 0.2 C to measure the initial capacity, and the resultant initial capacity was employed as a battery capacity.
<Energy Density>
The battery capacity was multiplied by the average voltage and divided by the battery volume to calculate the energy density. At that time, the average value of the voltages at SOC 0%, 20%, 40%, 60%, 80% and 100% was used as the average voltage.
<Battery Capacity/Thickness Ratio>
The battery capacity (mAh) was divided by the thickness of the battery (mm) to calculate the battery capacity/thickness ratio (mAh/mm).
<Constant Voltage Charge Cycle Performance>
