The main advantage of lithium batteries is that they can emit large amounts of electricity at a smaller volume or self-weight

Lithium is the lightest metal element in nature. With lithium as the negative pole and matching with the appropriate positive pole, an energy mass ratio of up to 380W · h/kg to 450W · h/kg can be obtained.

A battery that uses lithium as a negative electrode is called a lithium battery. As a primary battery, one is a lithium battery using lithium perchlorate as an electrolyte, a Polyfluorocarbon as a positive electrode material, and a lithium battery using lithium bromide as an electrolyte from sulfur dioxide as a positive electrode material.

The main advantage of lithium batteries is that at a smaller volume or self-weight, they can emit larger electrical energy (much larger than energy than zinc silver batteries). When discharging, the voltage is very stable, the storage life is long, and it can be very wide. The temperature range works effectively. The application is the same as zinc silver batteries. From the development trend, lithium batteries will be more competitive than zinc silver batteries.

The commonly used solar cells are made of Silicon. Generally, a thin layer of boron is penetrated into the small sheet of electronic monocrystalline Silicon by diffusion method to obtain a PN Junction, followed by an electrode. When sunlight hits a thin layer of boron, an electromotive force is generated between the poles. This battery can be used as a power source for instruments onspecials. In addition to Silicon, gallium arsenide is also a good material for solar cells.
