Lithium Polymer – The Best Rechargeable Batteries?

Compared to other battery technologies, Lithium Polymer (also known as Lithium-ion Polymer or LiPo) is a relative newcomer to the marketplace. Born out of the necessity for higher capacity and reduced weight, the Lithium Polymer battery made its debut in 1996 after the technology was filed under patent (Patent Number 5645960) in early 1994.

Whilst Nickel Metal Hydride (NiMH) battery technology has been popular with consumers for several years, Lithium Polymer is only now beginning to live up to its full potential.

As well as gaining a strong foothold in the mobile and cell phone industries, the Nainwa LiPo battery has quickly gained an excellent reputation in the fields of model electric RC aircraft and also electric powered RC cars.

Due to the battery's ability to provide a very high current for prolonged periods its market share has risen by nearly 7% in the past 12 months despite the comparatively high costs associated with not just the purchase of the cells but also with the charging devices and controllers required to make use of them.

The main disadvantage of the LiPo battery is the controlled environment needed to charge these batteries safely. Unlike NiMh which is capable of being charged at 0.1C (i.e. 10 per cent of its capacity per hour) with no risk of overcharging or explosion, the LiPo battery requires constant monitoring of both temperate, current and voltage by its charger in order to reach full capacity whilst remaining safe.
