ML1225 Rechargeable Lithium Coin Cell is a new type of rechargeable Li-ion button cell, with a positive material of LixMnO2 instead of LiCoO2, and a negative material of Li-AL alloy instead of C. With a 3.0V voltage, stable cycle performance and perfect safety performance, the ML button cell is becoming the most popular type of Li-ion battery.
Specification
ML1225 Rechargeable Lithium Coin Cell employs specially treated manganese dioxide for the
positive material and a lithium-aluminum compound for the negative material. A specially
formulated organic electrolyte is also used, yielding excellent discharge characteristicswith low self-discharge.

Benefits of ML1225 Rechargeable Lithium Coin Cell
Perfect safety performance
the ML button cell doesn’t have the danger of over charge and over discharge. And the vibration,
short circuit, nail pricking, impact, crush, drop and other safety tests meet the UL request.
Good over charge endurance
the thermal change in high temperature is very small, and the stability and endurance for over charge is good.
Superior discharge performance
the discharge curve is stable and the cycle life, charge and discharge efficiency is superior, it is good for electric equipments.
Good cycle life
the material of ML button cell won’t occur the volume effect which affects the electrochemistry reaction : That is the reason
why the material have good cycle performance. And the rest capacity will keep more than 80% of initial capacity after 200~300 cycles.
Good shelf life
The shelf life of Li-ion battery can be tested by the size of self-discharge. There are two types of capacity loss for self-discharge, one is
restorable capacity and the other is non-restorable capacity. The restorable capacity can resume 95%~98%.
Key Features of ML1225 Rechargeable Lithium Coin Cell
High operating voltage, more than twice as high as Ni-MH batteries
Excellent safety performance, free from any risk of overcharging and over-discharging
Excellent discharge performance, stable discharge, and excellent cycle performance, with no volume effect during charging and discharging
Low-current charging can be widely used as a memory power source for PC and so on
