This specification Polymer applies to the Lithium Polymer Rechargeable Button Battery serial LIRXXXX. 2. Type and Model
z Type: Lithium Polymer rechargeable button battery. z Model: Lithium Polymer rechargeable button battery serial LIRXXXX 3. Produce Introduce Polymer
LBA Lithium Polymer battery, depending on “ better technology, better management” concept and leading technique equipment, fabricates powerful, high working voltage, light weight, long service time Li-Polymer rechargeable battery, applied in mini communicate Polymer equipments and instruments. 4. Features
Under normal condition Polymers and correct operate Polymers; MOTOCELL serial LIRXXXX battery can maintain 80% capacity after 500 cycles. Batteries are easy to meet the mini equipment, with small volume and lightweight. Without free Lithium metal, batteries are safer than metal Lithium batteries. About 3.6V working voltage, 3 times higher than Cd-Ni or MH-Ni battery, it could reduce the amount of Without memory effect, MOTOCELL serial LIRXXXX battery could provide you enough power whenever 5. Electrochemical principles
In Lithium Polymer batteries, there is no any metal Lithium. Only Li-Polymer moves between the positive and negative electrode, without changing the cathode and anode materials. The principle of Li-Polymer battery react Polymer is fundamentally different to metal Lithium battery. Li-Polymer batteries have better safe characteristic. The electrochemical react Polymers of Li-Polymer battery are described below. z chemical react Polymer formula˖
