Lithium is the lightest of all metals, has the greatest electrochemical potential and one of the largest energy density per weight provides. Lithium metal anode (negative electrode) Rechargeable batteries are used in high power, high voltage and high energy density leads to an emergency and is capable of providing.

In 1980, after years of research, a lot of Polymer Lithium ion Battery, lithium electrode cycling was found to be the cause of the changes. These changes are part of the natural wear and tear, low temperature stability, potential problems caused by heat loss. At the moment, the temperature quickly the mobile space, the so-called "fire, said," As a result, approaches the melting point of lithium. Japan rechargeable lithium batteries sent right to your mobile phone number of the person who set fire to the gases, causing facial burns and battery, then it was back in 1991.

Lithium metal, especially during charging due to the instability of the investigation, there is no metal-ion battery used in lithium batteries. Slightly lower energy density than lithium metal, though, the lithium ion private security measures to ensure the safe loading and unloading. In 1991, the Sony Corporation commercialized the first lithium-ion battery. Other manufacturers followed suit. Today, Li-Ion battery of the fastest growing and most exciting technology.

Lithium-ion battery, nickel-cadmium batteries are usually twice the energy density of the way. Nickel-cadmium electrode three times on the improvement of active components that have the ability to increase the energy density. In addition to the potential for a good, very good, and the discharge of cargo volume attributes (similar style to the discharge profile, but different voltage) of the same act for nickel-cadmium. Flat discharge curve is the efficient use of Power Bank stored in a desired voltage range.

This low-maintenance lithium-ion battery and other chemicals can not claim that it is an advantage. No memory and does not need to extend the battery life on a regular bike. In addition, the self-discharge is suitable for modern fuel gauge applications, Ni-Cd and NiMH lithium ion, resulting in comparison with less than 50 per cent.
