Battery Basics: Chemistries
Batteries all store chemical energy and convert it to electrical energy, which in turn powers your device. They have two electrodes:
– a positive one called the cathode and a negative one called the anode
– an electrolyte and something to separate the cathode and anode.
The chemistry of a battery tells you what materials it uses, and for most vaping batteries – and most modern batteries in general – lithium characterises their chemistry. The anode for lithium ion batteries is made from carbon/silicon and graphite, but the cathode material differs and gives each battery unique characteristics.
When you buy a vaping battery, it will be identified by a series of letters like “IMR” or “ICR,” and these tell you about the make-up of the battery. The “I” means lithium-ion and will be the same for any battery you buy for a E cigarette device, and the “R” stands for rechargeable. However, the other letters tell you other materials used in the battery.
C stands for cobalt
F stands for iron
M stands for manganese
N stands for nickel
So this means that an IMR battery is a lithium-manganese and an ICR battery is a lithium-cobalt. The specific chemistry of the battery tells you a bit about how it will perform, and a couple of chemistries are worth covering specifically:
IMR (Lithium-manganese) batteries allow a lot of current to flow without increasing the internal temperature of the battery too much. This makes them much safer to use for vapers, and they don’t need protective circuitry built in because the design is intrinsically safe.
INR (Lithium-manganese-nickel) batteries offer many of the benefits of IMR batteries (largely due to the manganese), but add nickel to produce a “hybrid” chemistry battery. In practice, this means INR batteries offer high current, low operating temperatures and higher capacity than IMR chemistry batteries. Popular vaping batteries like the Sony VTC 4 and 5, the LG HE2 and the Samsung 25R use INR chemistry.
ICR (lithium-cobalt) batteries are the highest-energy battery chemistry you might use for vaping, but they don’t do as well as the others when it comes to safety. They need additional protective circuitry (which is added by a third-party company) to be used in a mod, but they are very limited because the highest current you can safely use them at is shown by the mAh rating (which we’ll cover in more detail later).
