What is the Purpose of the Supercapacitor for Battery?

The supercapacitor resembles a regular capacitor with the exception that it offers very high capacitance in a small package. Energy storage is by means of static charge rather than of an electro-chemical process that is inherent to the battery. Applying a voltage differential on the positive and negative plates charges the supercapacitor.
This concept is similar to an electrical charge that builds up when walking on a carpet. The supercapacitor concept has been around for a number of years. Newer designs allow higher capacities in a smaller size. Supercapacitors are relatively expensive in terms of cost per watt. Some design engineers argue that the money would be better spent in providing a larger battery by adding extra cells. But the Supercapacitors and chemical battery are not necessarily in competition. Rather, they enhance one another.

If I overcharge my laptop hp Pavilion dv9000 battery, will the life span decrease?

First it’s important to understand what overcharging is:
Over-charging occurs when the charger keeps the HP Pavilion dv9000 battery at a temperature that is warm to touch (body temperature) while in ready condition.
Li-Ion HP Pavilion dv9000 batteries have built-in controller chips which prevent it from overcharging, as they can explode if overcharged. Overcharging does not affect the life span other than potentially destroying the HP Pavilion dv9000 battery.
A lithium-based HP Pavilion dv9000 battery should never be allowed to get warm in a charger. If you have this happen, the HP dv9000 battery is no good or the charger is not working properly. Don’t continue to use the HP dv9000 battery or charger if this happens.
A Lithium-ion HP Pavilion dv9000 battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours). Damage to the battery HP Pavilion dv9000 from overcharging would only occur in the very unlikely event of a malfunction of the charging system.
