Comparing Cell Energy Density of Two Chemistries

This case study will highlight the importance of reporting new electrode active material performance parameters in full cell architectures. It will also discuss the need to understand the limits of different cell chemistries, and why any extrapolation of future performance must take into account the physical realities of the materials. The performance of electrode active … Read more

NMC Composition

NMC

NMC Composition can be difficult to understand at first and so here is a walk through the compositions and what they actually mean. The 33%,33%,33%, in NMC111 is the composition of Ni, Mn, Co among themselves rather than the compound (Li Nix Mny Coz O2) as a whole.    I have calculated the % m/m of all elements … Read more
