Exell IMR 18650 3.7V LiMN 2000mAh Rechargeable High Drain Flat Top Battery
Exell 18650 3.7V 2000mAh LiMN Battery is an ideal replacement battery for many of todays in demand applications such as E-Cigarettes also known as MODS, Vaporizers or Vape products as well as high intensity LED flashlights and Solar Lamps used in gardens and walk ways.This LiMN battery has three-dimensional tunnels that enable rapid diffusion of Li+ through LiMn2O4 particles, and therefore lithium-ion cells made with this material can have better theoretical drain rate capability. Conventional lithium-ion cells use LiCoO2 or variations of that material. Cells with LiCoO2 cathodes are typically designated with the term "ICR". The LiCoO2 type materials have a layered crystal structure that only enables 2D diffusion within the layers, so the overall Li+ diffusion rate is slower.
Li-MN batteries have a lower crystalline density and therefore a lower inherent capacity (mAh/ml) than LiCoO2. If you do a direct replacement of LiCoO2 with LiMn2O4, the capacity of the cell will be reduced by ~15%. But here is the interesting thing: simply doing a direct replacement with LiMn2O4 will not significantly increase the rate capability of a cell. In order to get a real increase in rate capability, you need to design a cell with higher electrode surface area and thinner electrodes because Li+ diffusion in the cathode particles is not the only bottleneck to getting current out of the cell. Using thinner electrodes further reduces the capacity of the cell because you will have a higher fraction of "inert" materials like the separator and current collector. This is why IMR cells typically have ~40% lower capacity than their ICR cousins.Exell 18650HP 3.7V 2000mAh LiMN Battery Specifications

An additional property of LiMn2O4 is that it cannot be overcharged. When a "true" IMR cell is charged beyond ~4.25 V, no additional capacity will go into the cell. The voltage will simply spike. This is exactly the same case for LiFePO4 cells. Cells that use LiCoO2 and its layered-metal oxide cousins can be overcharged, leading to significant safety issues when these cells are charged above their specified voltages. Cells with LiMn2O4 and LiFePO4 cathodes can be damaged by overcharging (oxidation of the electrolyte leads to increased internal resistance, loss of capacity and shorter cycle life), but overcharging to higher voltage does not make them less safe. This inability to overcharge, combined with the lower total energy density, is why lithium-ion cells with LiMn2O4 and LiFePO4 are generally considered to be "safer".
The last property of LiMn2O4 is that in its pure form it tends to have very poor cycle life. There has been a tremendous amount of research that has gone into improving the stability of LiMn2O4 to improve the cycle life of IMR cells, and this has produced cells with reasonably good long term performance. However, the easiest way to get great cycle life out of LiMn2O4 is to blend it with a separate cathode material that contains nickel. This includes the layered cathode materials Li(Nix,Cox,Mnx)O2 (aka NCM or 333), Li(NixCoyAlz)O2 (aka NCA) and Li(NixCoy)O2 (aka NCO). I won't bore you with the details, but it turns out that the oxides containing nickel acts to change the local chemistry around the LiMn2O4 particles and helps to improve stability.
