Before we will answer the question, we will present you what Li-ion battery is and how it is constructed. Li-ion battery is a kind of battery which has one electrode made of carbon and the second one of metal oxide. As an electrolyte, the battery is using compound chemical lithium salts dissolved in mixed organic solvents. The battery has no memory or the lazy battery effect. It is worth to mentioned that the technology, in comparison with nickel-metal hydride, can cumulate even 2 times more energy with the same load and size.
