Exell IMR 18500 3.7V LiMN 1100mAh 15AMP Rechargeable High Drain Flat Top BatteryExell IMR 18500HP11 3.7V 1100mAh Li-MN Battery is an ideal replacement battery for many of todays in demand applications such 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.Interestingly, LiFePO4, which is commonly used in high rate cells (think A123), has 1D diffusion of Li+ and an overall low diffusion rate. The only way to make LiFePO4 work is to make the particles very small (i.e. “nano”) to reduce the distance that Li+ needs to diffuse. “Why not just make LiCoO2 or LiMn2O4 nano size to get even better rate capability?” I hear you ask. The only reason nano LiFePO4 works is that this material has a lower oxidizing potential (which is why the cell voltage is lower) and therefore it does not chemically react with the electrolyte. LiCoO2 and LiMn2O4 actually oxidize the electrolyte slowly with use, so using a nano-particulate cathode with these materials would greatly accelerate aging due to the higher surface area of the cathode, and the cells would have terrible cycle life.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
