Wrong , there will be a lot more silicone in future batteries , keep it real Blackfrost , Silicon holds 10 times the energy than graphite and charges much faster , silicon is made from sand , very abundant and cheap , see Tesla they are increasing the % of silicon in their battery for more energy and faster charging , your Ecograph project is stuffed if it can't remove the silicone and molecular glue self healing binder from batteries , can't believe EGR's done no testing on that ? done no costings transporting old batteries from around the globe ? its my opinion your graphite project has no margins and is dead , the $50 million in the bank will be used to find another project ,probably in WA , EGR ? when does the option expire ?
Tesla Silicon Anode Will Be the Key to Next-Level Fast Charging
In a Q3 2020 Earnings Call, Tesla SVP Drew Baglino said that the fundamental limiting factor for high charge rates is lithium plating, which can be eliminated with proper electrode design and material choice. Tesla Silicon is the right material to provide the right electrode design.
Panasonic introduced 2170 nickel-cobalt-aluminum (NCA) cathode chemistry in 2017 for Tesla Model 3. But the company said it has been developing the technology, resulting in an increase in specific energy of more than 5%, and a reduction in cobalt content to at most 5%. Panasonic also plans to increase the power density of its batteries that it supplies to Tesla by 20% in five years, and to commercialize a cobalt-free version "in two to three years."
In early November, Celina Mikolajczak, vice president of battery technology at Panasonic Energy of North America (PENA), revealed that the company is working on a new battery pack that will be based on the recently unveiled Tesla 4680 battery, and will feature fast-charging capability.
Jordan explains that the 5-20% increase in energy density is most likely to be largely driven by the higher silicon content. This gradual increase in silicon will over time lead to faster battery charging rates.
Jim Cushing of Applied Materials is developing a 30% silicon anode battery that provides a 4C charge rate (0-100% in 15 minutes). This means that, in the first five minutes, the battery can be charged from 0 to 50% if the charger is powerful enough to deliver that amount of energy.
