Solar power for cobalt deprecated in battery industry also made these attempts1

Similarly, China solar energy network, ningde, the CTP technology of The Times, namely Cell to PACK, by reducing the production of parts and components, battery energy density can reach 200 wh/Kg. In fact, in the face of increasing costs, the global battery suppliers and car companies are trying to reduce the cobalt content in the ternary batteries, such as change the battery cathode material formula ratio, the three yuan in nickel cobalt manganese battery or nickel and cobalt ratio of aluminum from 6:2:2 8:1:1 instead. In addition, don't go to the garbage power plant work tesla relevant personage also said, tesla will have independent research and development new batteries, batteries are expected in April investors meeting battery components and other specific information. In addition, there were no back IBM ambry also is developing a cobalt free electric vehicle batteries, mainly depends on three kinds of material, extracted from seawater using a excluding cobalt and nickel cathode materials, China solar power network, and a liquid electrolyte with a high flash point safety. ” Musk was on twitter that their current Model 3 car batteries, there are less than 3% of the cobalt, and they will improve the technology, strive for to abandon cobalt in the next generation of batteries. The bulk density can be increased by 50%, thereby increasing the vehicle range. , tesla relevant personage says a cooperation agreement with the era of ningde, solar portal, ningde era production of lithium iron phosphate battery itself does not contain cobalt, but whether the cooperation will eventually fall to the ground did not comment. Don't go to the garbage power plant to work according to foreign media reports, tesla is working with the era of ningde discuss factories in China to use and other Cobalt free battery & throughout; The matters. Lithium iron phosphate battery with low cost and good safety performance advantages, but compared with the ternary lithium batteries, lithium iron phosphate has obvious short board, solar equipment, is the low energy density. This unique combination of cathode and the electrolyte is proved in the process of charging inhibit the ability of metallic lithium dendrite, which reduces the flammability, which could remove the metal lithium as a major drawback of the anode materials!

no matter the cost, ideal heat charging time, power density, efficiency and so on various aspects, solar energy, is better than the current widespread use of lithium ion batteries. Therefore, cobalt free battery technology has been a bottleneck period, how to break through a focus problem. Therefore, since the ternary batteries are widely used, the lithium iron phosphate installed proportion dropped year by year, to 2019 Q1-2017 Q3 lithium iron phosphate installed passenger cars accounted for 22%, 8% and 4% respectively. However, the higher the proportion of nickel, the thermal stability of the positive electrode material is the worse, ambry not back monitoring system on security of the more difficult it will be guaranteed. Head of panasonic battery tamura, said & other; We have greatly reduced the cobalt content in batteries, cobalt in the ternary battery has dropped to 3%, now our goal is to realize the cobalt free, this technique has been developed. However, as the byd launched in January this year for mid-range models & other; The blade battery & throughout; Lithium iron phosphate and back into focus. If finally landed, it also means that the lithium iron phosphate batteries will be the first to enter the tesla production line, is expected to lower production cost, improve the relevant vehicle sales in China. These two technologies to improve the vehicle range, reduce the battery cost has important meaning. In terms of cobalt free battery technology, panasonic is particularly aggressive, hope the cobalt content in the ternary cell down to zero.
