The battery is the power base of the electric model. More than 20 years have passed, and power batteries have significantly developed. Nickel-metal hydride batteries and polymer lithium batteries have also entered the field of model aircraft. Let\’s take a look at a brief history of the development of RC lithium polymer battery.
A model that is started by using a motor is called an electric model, and a battery for operating the engine is a powerful battery. It is essential for the flight performance of model aircraft.
There are many types of batteries used in electric model aircraft, such as solar cells, silver-zinc batteries, lithium batteries, nickel-cadmium batteries, and nickel-metal hydride batteries. The output current of the solar cell is small, so a large area must be made for the electric model to fly, and it is expensive, so it is rarely used. Silver-zinc batteries have high specific energy and high current discharge capacity, but the battery has a short life and is costly, easy to leak, and easy to fall, so no one cares. At present, popular batteries used in model aircraft are nickel series batteries (nickel-metal hydride batteries) and new lithium batteries (polymer lithium batteries).
In the early stages, research on lithium batteries was mainly used in the military, and later in civilian use, people paid more attention to their development and investment with substantial economic benefits. As a result, breakthroughs were made in the late 20th and early 21st centuries. At present, lithium batteries have been used in mobile phones, cameras, laptops, and other fields. Replacing nickel-cadmium batteries and nickel-metal hydride batteries. In recent years, it is still used for RC lithium polymer battery. At first, hobbyists tried to use a cell phone lithium battery placed on a remote-controlled aircraft to make a flight and obtained longer flight time than a nickel-cadmium battery. Later, it attracted manufacturers in two industries. They have successfully researched the polymer lithium battery. After the lithium battery material and the electrolyte polymer are combined, the lithium battery performs better in high-current discharge capacity and is more suitable for the aviation model. Therefore, the lithium polymer battery has become Mainstream varieties. According to long-term development, from now on, lithium polymer batteries will provide power for model aircraft for a long time.
