An Analysis of Points of Attention for Using Polymer Lithium-ion Battery

Points to Note for Using Polymer Lithium-ion Battery

Attention to the operation of the electric core

Since the core is a soft packaging, in order to ensure that the performance of the core is not damaged, it must be careful to operate the core.

1. Aluminum foil packaging materials

Aluminum foil packaging materials are easily punctured by sharp parts such as nickel chips and needles.

No colliding batteries with sharp parts.

The work environment should be cleaned to avoid sharp parts

Do not puncture batteries with nails and other sharp objects.

It is forbidden to transport or store batteries with metal objects such as necklaces, hairpins, etc.

2. Top Cover

The top edge is very vulnerable.

No bending of the top cover

3. Fold

The folding edge was completed during the battery production process and passed the seal test.

Do not open or break the hem.

4. Ultimate Ears

The mechanical strength of the polar ear is not unusually strong, especially aluminum chips.

No bending of ears.

5. Mechanical impact

No falling, impact, bending of the core.

Do not hit or step on batteries with a hammer.

Do not hit or throw batteries.

6. Short Circuit

No short circuit is allowed at any time. It will cause serious damage to the core.

It is forbidden to connect the positive and negative electrodes of a battery with a metal such as a short circuit of a wire.

Standard environment for testing polymer lithium-ion batteries

Environmental temperature: 20 ± 5 °C

Relative humidity: 45 to 85 %

The battery must be discharged before testing.

III. Attention to Polymer Lithium-ion Electric Charging and Discharge

1. Charging

Charging current and charging voltage must not exceed the following standards. If the specified value exceeds the specified value, it may cause damage to the charging and discharge performance, mechanical performance and safety of the core, and may lead to heat and leakage.

The battery charger must be capable of constant current-constant pressure charging;

The charging current of the single battery at charging must be below 1C5A;

The temperature range at charging is 0 ~ +45 °C;

The voltage cannot exceed 4.23 V when charging.

2. Discharge

The discharge current shall not exceed the following standards. The discharge shall be carried out within the scope of this standard.

The discharge current of the single battery must be less than 2C5A;

The temperature range at discharge is -20 ~ +60 °C;

The discharge termination voltage of the single battery is not less than 2.75 V.
