4.4 Mechanical Specification

* Remaining Capacity : After storage, cells shall be discharged with Std. condition(4.1.2) to measure the remaining capacity.
** Recovery Capacity : After storage, cells shall be discharged with fast discharge condition(4.1.3), and then cells shall be charged with std.
charge condition(4.1.1), and then discharged with Std. condition(4.1.2). This charge / discharge cycle shall be repeated three times to measure
the recovery capacity.
Condition
Cells shall be charged per 4.1.1 and stored in a
temperature-controlled environment at 23ºC ±
2ºC for 30 days. After storage, cells shall be
discharged per 4.1.2 to obtain the remaining
capacity.
Cells shall be charged per 4.1.1 and stored in a
temperature-controlled environment at 60ºC for
1 week. After storage, cells shall be discharged
per 4.1.2 and cycled per 4.1.3 for 3 cycles to
obtain recovered capacity
Cells are charged per 4.1.1 and stored at 60ºC
(95% RH) for 168 hours. After test, cells are
discharged per 4.1.2 and cycled per 4.1.3 for 3
cycles to obtain recovered capacity.
65ºC (8h) ← 3hrs → -20ºC (8h) for 8 cycles
with cells charged per 4.1.1 After test, cells are
discharged per 4.1.2 and cycled per 4.1.3 for 3
cycles to obtain recovered capacity.
Cells shall be charged per 4.1.1 at 23ºC ± 2ºC
and discharged per 4.1.2 at the following
temperatures.
