This product specification has been prepared to specify the
rechargeable lithium-ion cell
('cell') to be supplied to the customer by Samsung SDI Co., Ltd.
2. Description and Model
3. Nominal Specifications
3.8 Max. Charge Current
3.9 Max. Discharge Current
5. Appearance
There shall be no such defects as scratch, rust, discoloration,
leakage which
may adversely affect commercial value of the cell.
6. Standard Test Conditions
6.1 Environmental Conditions
Unless otherwise specified, all tests stated in this specification
are
conducted at temperature 25±5℃ and humidity 65±20%.
6.2 Measuring Equipment
(1) Ammeter and Voltmeter
The ammeter and voltmeter should have an accuracy of
the grade 0.5 or higher.
(2) Slide caliper
The slide caliper should have 0.01 mm scale.
(3) Impedance meter
The impedance meter with AC 1kHz should be used.
7. Characteristics
7.1 Standard Charge
This "Standard Charge" means charging the cell with charge current
1300mA and constant voltage 4.2V at 25℃ for 3hours.
7.2 Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity
of the cell, which is
measured with discharge current of 520mA with 2.75V cut-off at 25℃
within 1hour
after the standard charge.
Standard Discharge Capacity ≥ 3500mAh
7.3 Initial internal impedance
Initial internal impedance measured at AC 1kHz after rated charge.
Initial internal impedance ≤ 100mΩ
7.4 Temperature Dependence of Discharge Capacity
Capacity comparison at each temperature, measured with discharge
constant current 520mA and 2.75V cut-off after the standard charge
is
as follows.
Note: If charge temperature and discharge temperature is not the
same,
the interval for temperature change is 3 hours.
■ others
Don't fold the battery cased with laminated film such as pouch and
Polymer.
Don't store the battery in a pocket or a bag together with metallic
objects such as keys, necklaces,
hairpins, coins, or screws.
Don't short circuit (+) and (-) terminals with metallic object
intentionally.
Don't pierce the battery with a sharp object such as a needle,
screw drivers.
Don't heat partial area of the battery with heated objects such as
soldering iron.
Don't hit with heavy objects such as a hammer, weight.
Don't step on the battery and throw or drop the battery on the hard
floor to avoid mechanical shock.
Don't disassemble the battery or modify the battery design
including electric circuit
