The anode all the Li-ion batteries 18650 is basically the same: carbon / silicon and graphite. Being the cathode where differing models and manufacturers, giving each a reference to its unique characteristics.

According to the chemical used in the manufacture of the cathode, we can choose models of batteries with the following outstanding characteristics such as capacity, cycle life and safety. For example, (based on cobalt) called ICR are of high ability, but are not very safe. IMR are safer, but have lower capacity than the ICR. And those that use nickel and manganese (IMR) gives a higher discharge current.

IMR: Allows the battery to discharge at a high current and maintaining a low temperature. Most of the batteries IMR do not require built-in protection circuit.

INR: The chemistry of the battery resulting gives a reasonably high capacity and a high discharge current. It is important to note that they are very stable, which means that it does not need protection circuits built-in.

NCA: This chemical is similar to the INR, but have a discharge currents to be lower. But they compensate with large capacities and their maximum duration. They also tend to be more shock resistant, so a good option for bikes and other electric vehicles. Tesla uses for their electric cars.

ICR: This chemistry provides a higher capacity than the others mentioned above. But also being the most dangerous of all the family 18650. You must take into account the high-intensity discharge, such as can not download it with a current higher than its specification.

It is therefore recommended the use of protection circuits when using these batteries.
