Lithium-ion laptop batteries

11th Aug 2015

Although laptop batteries look plain from outside, they nevertheless have internal parts that are enclosed in a casing. A typical laptop battery consists of interconnected cells and an electronic circuit. The circuit regulates the voltage and current produced by the cells.

Lithium-ion cells, commonly abbreviated as Li-ion, are the most common cell types used in laptop batteries. A battery is usually made up of six to eight cells that are interconnected to produce voltage that is enough to meet the power needs of a laptop. To avoid short circuits and enhance the safety of the user, lithium-ion cells are usually enclosed in casings. In addition, safety warnings are included on the casing of a battery to caution users from mishandling it.

Lithium-ion cells are mainly preferred because of their high energy density and good load characteristics. Furthermore, a lithium-ion battery does not require scheduled recycling to prolong its life.

Lithium-ion cells require protection circuits for safe operation. The protection circuit monitors and controls the charging and discharging processes. The temperature of a battery is also monitored to avoid extreme conditions that can interfere with its safe operation. Lithium-ion laptop batteries are also highly susceptible to aging. The capacity of a battery deteriorates as it ages.

Pros

i.                     They have a high energy density.

ii.                   The rate of self-discharge is low.

iii.                  No prolonged priming is needed for new batteries.

iv.                 They are ideal for applications that have high current needs.

v.                   Lithium-ion cells have low maintenance needs.

Cons

i.                     They are subject to aging both when in use and when not in use.

ii.                   The cost of manufacturing is relatively high.

iii.                  Lithium-ion cells require protection circuits that control and regulate voltage and current within safe limits.

Warning

Most lithium-ion laptop batteries have a warning section on the casing to caution users against mishandling them. Some of the things that safety warnings caution people from doing include the following:

i.                     Subjecting the batteries to extreme heat or placing them in fire.

ii.                   Shorting the terminals of a battery.

iii.                  Puncturing the battery.

iv.                 Reversing the polarities of a battery during installation.

v.                   Subjecting the battery to shocks or strong impacts.

vi.                 Keeping the battery in a wet or dump environment.

vii.                Disassembling a battery
