The Lithium battery- Battery or accumulator is an energy storage media are filled by the flow of DC from solar panels. In addition to storing the DC power, the battery also serves to convert chemical energy into electricity. With the battery, the electronic device or equipment will be operated even if no other source of electrical energy. The battery is needed for portable devices where the device is not always connected to a power source. Besides, the battery is also needed to for a solar-powered electronic device, because sunlight is a source of electrical energy in a solar power plant is only available during the daytime, while no at night. This will make the electronic device may not operate when the evenings. So, it takes the battery energy storage media. By using the battery, the electronic device will keep working even when there is no sunlight, for example, solar-powered street lighting. They remain brightly lit at night even though there were no sun rays because the battery as energy storage media is filled by the flow of DC from solar panels.
The battery comes in many choices of species, including the lithium battery. It is using the positive electrode of lithium cobalt oxide, lithium iron phosphate or lithium manganese oxide, usually graphite negative electrode and electrolyte of ethylene carbonate, diethyl carbonate. Electrolytes are stored in organic solvents between the electrodes. The whole circuit protection is also added to adjust the level of voltage and current within safe limits. The lithium battery has long been used for various purposes, including for batteries mobile phone or smartphone. The battery is constantly being developed and increasingly sophisticated battery capacity ranging from small to large. These batteries can also be used for various purposes of use. Including for operate household electronic equipment that requires high power.
These types of lithium batteries are divided into two lithium ion and lithium polymer batteries, although it was different but both are the same. There is a lot of merits which include Lithium ion batteries have a high-energy density, has a long shelf life, so it is more durable and can be replaced by the user. In addition to excess, this battery also has some shortcomings such as heavier size, circuit protector adds to the cost, has a self-discharge rate is relatively high. Lithium-polymer basically has the same components as the lithium-ion battery. The main difference lies in the materials or parts separator where the ions move between the electrodes. Just like types of lithium-ion, lithium polymer is also protection circuit to ensure the voltage is within safe limits. Compared to lithium ion is more efficient, in addition to the battery is also lighter, available in many forms, but it tends to have a low energy density, and the price is relatively more expensive when compared with lithium ion.
The lithium battery is also widely used to support a solar-powered device. So, do not be surprised if you’ll find a lot of solar-powered devices are powered by lithium batteries, either electronic device is off grid and on grid.
