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 of 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, increasing 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.
