Low Cost Ni-Co-Mn Free Cathode for Lithium Ion Battery
Nrgtek Inc. has created a new, patent pending, low-cost cathode material for lithium-ion battery (LiB), which does not use heavy/transition metals (cobalt, nickel, manganese, aluminum etc). The new cathode has a higher voltage and improved energy capacity and power density than current LiB systems.
Electrode materials for LiB
Material costs of current LiB have steadily increased, from 25% to 45-55% of the total battery costs, while the production and assembly costs have come down, from 75% to 45%. The main reason is the increase in costs of cobalt and nickel for cathode materials, while our cathode material costs are around $1,500-2,500/ton. The new cathode material is being tested successfully for energy storage capacity and cycle life at the company's battery test facilities, and further technology validation (cycle life, degradation characteristics and performance) will be completed during the next 2 years. The projected system costs are $250/KW and $75-100/kWh, as compared to current LiB systems at $750/KW and $150/kWh.

The new cathode material is a drop-in replacement for current LiB giga-factory manufacturing lines. One of the main advantages of the patent pending new LiB cathode is the use of low-cost sustainable raw materials, widely available in the US and internationally.
