Reasons and causes of the recall
Von laptop, 03:39According to Sony Energy studies have shown that the causes for the “defective” Lithium-ion batteries during the manufacturing process have emerged.
For a complete Dell XPS M1530 battery Lithium-ion liquid is poured into a cylindrical metal housing. It is possible that small metal particles enter the cell. These particles during loading or discharging the battery through the thin separator inside the cell between the electrode wall and create an electrical short circuit.
In most cases, the Dell Latitude D630 battery would then shut off automatically. Denied this protection but increases the temperature in the cell very rapidly and there is a “thermal runaway”. In the most benign case, a gas leak occurs from a pressure relief valve of the battery. In the worst case it’s a dangerous fire explosion.
The problem with lithium is that it is water under very aggressive development of hydrogen to lithium hydroxide (LiOH) responding. Like all alkali metals is the soft, silvery-white light metal is very reactive. If there is damage or defect on or in the lithium batteries – as above – can be devastating.
Normally lithium-ion battery or the Dell inspiron 1525 battery pack by a number of security mechanisms, uncontrollable events are protected within the Dell Inspiron 6400 battery cell. Thus preventing specific resistance – so-called PTC – high current peaks. Excessive cell pressure, caused by high electrical voltage, interrupting a special built-in protection of the circuit. Additionally, through a safety valve, the excess cell pressure will be reduced. In addition, further holding a Dell Studio 1737 battery pack electrical protection circuits that monitor power, voltage and temperature and the cells respond to disturbances.
