LFP Battery VS Lithium Ion

Lifepo4 cylindrical cells generally refer to a secondary battery (rechargeable battery) that rely on lithium ions between the positive electrode and the negative electrode. During the charge and discharge process of lifepo4 cylindrical cells, Li + is built and deodded between two electrodes; LFP battery cells are specifically referred to lithium ion batteries in lithium iron phosphate as a positive material, except for lithium iron phosphate batteries, the lifepo lithium battery also includes a lithium cobalt organte, a ternary battery, etc. In contrast, the lifepo cell energy density is slightly lower than the lithium cobaltate battery and the ternary battery, but has longer life, higher safety, no pollution, and low price, currently widely used in the new energy vehicle applications.

Lifepo4 cell voltage chart

Including charging maps and discharge maps, charging is charged with the given current to the battery, the lifepo4 cell voltage gradually increases as time goes by, after the upper limit voltage is reached, the charging is completed; the time or the charging capacity is an X-axis, voltage change value The chart made for the Y-axis is charging. The discharge is discharged by the given current, and the voltage gradually decreases as time goes by. After the lower limit voltage is reached, the discharge is completed; with the time or discharge capacity of the X-axis, the chart of the lfp cell voltage change value is the Y-axis is Discharge. In addition, during the process of charging and discharging of lifepo lithium battery, voltage variation is very gentle, which means a relatively stable discharge platform.
