Lithium batteries! Most of us, who
use cell phones or laptops, must have heard this word. Since the early 1990s, these
batteries have powered portable electronic items. Now, these batteries are
recognized as future of the auto industry. Rechargeable lithium-ion battery has
become increasingly popular in electronic devices as these batteries hold
electric charges longer. Light weight as compared to other rechargeable
batteries, is another added advantage. Lithium-ion batteries are used in
various consumer electronic items like iPods, cell phones, digital cameras and
laptop computers. Many car manufacturing companies are now looking forward for
the use of these batteries in the cars.

industry and lithium auto battery,

Like all other industry, auto
industry has seen lots of alterations. Since last few years, we are facing
various problems like increasing fuel expenses, pollution, etc. All these have
forced us to find ways inexpensive renewable energy that will reduce auto
emissions as well. That has caused lithium batteries to be placed in some vehicles.
Until now, overheating problems and the environmental safety with lithium
batteries that affected laptops earlier appear to have been limited. Lithium auto battery is now preferred
choice due to its several benefits. Most of the lithium batteries, used in
automotives are lithium-ion batteries.
Let us have a look at features and
chemistry of lithium ion battery.
Lithium ion battery-
Chemistry
- Most lithium ion batteries use graphite as the anode. Generally, the cathode is made up of lithium cobalt oxide, lithium manganese oxide or lithium iron phosphate. The selection of cathode generally depends on the balance between charge deterioration, capacity and voltage.
- Safety is concern, because of explosions of a few mishandled lithium ion battery designs. Electrical current is produced by the movement of the lithium ion from the cathode to the anode, and is reversed while recharging. There is a thin layer or a medium between the anode and cathode. In general, it is an organic solvent plus a solid lithium salt.

ion battery-Features
- A lithium ion battery is designed specially to generate electricity through the movement of lithium ions between the anode and cathode.
- They offer one of the best power-to-weight ratios as compared to other available equivalent.
- Lithium ion batteries are rechargeable and easy to use.
Car
Fire Potential
Earlier there was concern for safety
of battery. Preventing Lithium-ion battery fires has been a major concern for
car manufacturers. Many car makers use a computer controlled liquid cooling
system, which helps avoid overheating. Overcharging a Lithium-ion battery can be
dangerous as lithium oxide can turn into metallic lithium due to excess heat.
This can increase the danger of a battery explosion. To address this issue, laptops
make use of "smart" Lithium-ion batteries that feature integrated
sensors to control current, temperature and voltage. This control can help keep
the batteries comparatively safe.
It is true that lithium batteries do have some
issues, but their advantages definitely make them better choice. Efforts, money
and time have been invested into developing systems to address these issues. Days
are no long, when lithium batteries will be used not only in laptops, cell
phones but also autos safely.
