lithium polymer battery

 

♣ Applications

Rechargeable Lithium cells are used a wide range of consumer products including cameras, camcorders, electric razors, toothbrushes, calculators, medical equipment, communications equipment, instruments, portable radios and TVs, pagers and PDA's.

They are fast replacing Nickel Metal Hydride cells as the preferred power in mobile phones. Laptop computers almost exclusively use Lithium batteries.

Testing method

1

Discharge performance under different temperature

 

Discharge capacity/standard capacity×100%

 

(A) -20℃≥50%

(B) 0℃≥80%

(C) 23℃≥100%

(D) 60℃≥95%

Charge with 0.5C3A standard charge in the condition of temperature 20℃±5℃, relative humidity 45%~85% (if there is no especial statement, the charging way is same as this, rest for 10min, separated discharge with 0.2C3A to cut-off voltage 3.0V under different temperature, cycles for three times. One cycle capacity arrive standard, that’s to say it is qualified.(The below as the same)

2

Self-discharge

Remain capacity ≥ standard capacity×97%

 

After standard charged,rest it in 20℃±5℃ for 1 months. Then discharge with 0.5C3A to 3.0V, testing the battery capacity.

3

Cycle life

Capacity≥ Standard

capacity×80%

After 0.5C3 standard charged, discharge with 0.5C3A to 3.0V, rest for 10min, and cycles for 1000 times.

4

Storage performance

Capacity can be kept ≥80% Storage for 12 months.

After standard charged,rest for 12 months, discharge with 0.5C3A to 3.0V, test the remaining capacity; 0.2C/0.2C test the recover capacity, cycle for 3 times. One cycle capacity arrive standard, that’s to say it is qualified.

♣ Quality Assurance

Kayo Maxtar in implementing ISO9001:2000 system, the quality assurance system makes of IQC, IPQC, FQC, QE, QA and Metrology. A complete number of standards ranging from raw material inspection, manufacture process, control to shipment inspection(QA); the advanced inspection equipments and detailed quality management files, which makes it possible to keep every processing step on the battery production lines in strict control.

 

♦IQC: inspect and control over all incoming materials and components to make sure that only qualified supplies flow into each production run.

♦IPQC: inspect and control over all of manufacturing processes. Being quality warning, every staff is called on to join efforts to maintain on going consistency and quality, and when anything goes wrong, correction is done quickly.

♦QA: in charge of all tests in QA division according to IEC standard and customers’ requirements.

♦QE: quality engineer work with product quality control system, manufacturing process technical issues and product implementation. Broad training enables them to analyze the processing and product construction changes, and solve both short-and-long-term problems.

♦FQC: final inspection on finished goods before shipment is to assure delivery without any defect.

♦Metrology: Metrology Control.
