LFP-NCO Theory Lithium iron phosphate cathode material is an olivine-structure compound and a semi-conductor material. When LiFePO4 was developed in 1996, it was N-type semi-conductor, it couldn’t be used for lithium ion commercial application because of its shortage of electrons, few electrical holes, low capacity and poor conductivity.
After 2001, the compound LFP was dramatically changed, other kinds of p-type semi-conductor were unveiled. Doping or coating methods were used to modify the non-commercial N-type LFP to the P-type semi-conductor which has more electric holes and less electrons, which increases conductivity one million times, to meet commercial demand.
Aleees developed LFP-NCO cathode material as a kind of p-type semi-conductor in 2007. NCO exists in lattices of LFP, metal Oxide is co-crystallized with Lithium iron phosphate in a solid solution, so a lattice effect is created and it is evenly dispersed over the material. This raises conductivity one million times and increases the capacity to 155mAh/g. Metal oxide not only solves the problem of inconsistency in product quality by controlling the ratio of iron 2 valence but also prevents Iron ion precipitation (Life Cycle Problem) on the anode; this is very helpful in raising the life cycle of a cell a thousand times.
Besides this,
NCO does not use the traditional doping or coating process to become a P-type semi-conductor, so the production procedure is simplified and cost savings are made.
NCO is the best solution for power lithium ion cells because of its great-performance and low-cost advantages.
LFP-NCO P-Type semiconductor increases conductivity 1M times over N-Type semiconductors
LFP-NCO successfully increases N-Type semiconductors’ 136mAh/g to 157.93mAh/g (21mAh/g increase)
LFP-NCO helps to prevent iron ion precipitation for enhancing the cycle life of lithium ion batteries.
