The difference between a 3.7 volt lithium battery and a 3.6 volt lithium battery is that the output voltage of the 3.7 volt battery is 0.1 volts higher than that of 3.6 volts. In actual use, the two batteries can be used as long as the appearance and wiring position.
"Lithium battery" is a kind of battery made of lithium metal or lithium alloy as anode material and non-aqueous electrolyte solution. Lithium metal battery was first proposed and studied by Gilbert N. Lewis in 1912. In 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Because the chemical characteristics of lithium metal are very active, the processing, preservation and use of lithium metal require very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium battery has become the mainstream.
Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium and can be charged. The fifth generation lithium metal battery of rechargeable battery was born in 1996, and its safety, specific capacity, self discharge rate and performance price ratio are all superior to lithium ion batteries. Because of its high technology requirements, only a few countries are producing such lithium metal batteries.
