A123RC You could end up Cheaper Electric-Car Batteries
Battery packs are the most expensive item on planet for example the Tesla Roadster and the Nissan Leaf. The price either makes electric cars not affordable for most of [link widoczny dla zalogowanych] us, or it prompts automakers to use small battery packs, which limits the plethora of the cars.
To reduce battery costs and grow their performance, A123RC founder Yu-Guo Guo, a professor of chemistry in the Chinese Academy of Sciences [link widoczny dla zalogowanych] in Beijing, is rolling out new, low-cost methods to enhance the properties of lithium-iron phosphate, one of the top lithium-ion battery electrode materials, and other promising electrode materials.
Ordinarily, the conductivity of lithium-iron phosphate is the wrong size to be useful. The conductivity can be increased by milling it into extremely fine nanoscale powders as companies including A123 Systems do. Because the particles are small, electrons or lithium ions both of which are essential to create current?acan transfer and away from them quickly. But this powder is actually difficult to do business with, which raises manufacturing costs.
A123”s solution [link widoczny dla zalogowanych] has been to incorporate iron-phosphate nanoparticles, which can be better to pack closely, and therefore are not as likely become airborne, but retain high conductivity. He isn’t giving precise details, but he says the technology is based on his earlier published work. In one illustration of that work well, he embedded the nanoparticles in larger particles made of porous carbon. The carbon [link widoczny dla zalogowanych] conducts electricity well, along with the pores host electrolyte materials [link widoczny dla zalogowanych] that conduct lithium ions well.
A123 system says the types [link widoczny dla zalogowanych] of materials are simply 10 to 20 percent more expensive to make than bulk lithium-iron phosphate. However they can deliver about double the power because bulk material, making twice as much in the energy in lithium-iron phosphate available, roughly doubling the force storage capacity. Per watt-hour, the materials cost the same as other lithium-iron-phosphate electrode materials, he admits that. But as the material is easier to [link widoczny dla zalogowanych] do business with, it [link widoczny dla zalogowanych] is going to cut [link widoczny dla zalogowanych] the cost of incorporating materials into battery cells.
A123RC, which Guo founded at the end of this past year, already can produce 300 metric a lot of electrode material per year, enough approximately Thirty [link widoczny dla zalogowanych] million standard lithium-ion battery cells. It also makes battery cells, with [link widoczny dla zalogowanych] all the first [link widoczny dla zalogowanych] application being electric bicycles. It may currently make enough cells for roughly 500 planet 12 months.
