pTesla will drive down batterypacklevel costs by 70 down to around 38kilowatthour once the Gigafactory hits peak production via economies of scale improved chemistry supply chain optimization and other factors according to Jefferies analyst Dan Dolevp

pAs part of his recent appraisal of the company the analyst increased his price target for Teslarsquos stock up to 365 a share mdash largely owing to his analysis of the companyrsquos battery business As company executives have previously forecast a cost reduction of around 30 the new analysis seems to suggest that that was a very ldquoconservativerdquo estimate perhaps meant to be greatly exceeded for PR purposes or simply because so many factors wereare still in the airp

pThe analyst in question is basing this prediction around an estimation that current Model S batterypack costs hover somewhere around 250kWh kilowatthour mdash and that the company ldquocan bring the cost of the battery cells down to 88kWh and the packlevel cost to 38kWhrdquop

pWe believe that Teslarsquos use of an efficient nickel cobalt aluminum NCA cathode ie the positive electrode use of a silicon synthetic graphene anode ie the negative electrode that has 26x the lithiumion storage capacity of todayrsquos standard graphite anode and a possible use of waterbased anode solvent are key advantages hellip Our analysis details a potential path to a 30 celllevel cost reduction to 88kWh by using a more efficient lithiumrich nickel cobalt manganese cathode vs NCA doubling the percentage of silicon in the synthetic graphene anode replacing the liquid electrolyte with an ionic gel electrolyte which eliminates the need for a separator and using a waterbased electrode solvent for the cathode The Gigafactory which is expected to begin production in early rsquo16 should drive down packlevel costs by 70 to 38kWh via economies of scale supply chain optimization increased automation and production domesticationp

pAs noted by Electrek that puts things in the sorts of ranges that would probably allow for a very affordable electric vehicle EV with a 200ndash300 mile plus rangep

pWith regard to the estimation that Tesla Model S battery packs cost around 250kWh at the moment it should probably be noted here that the companyrsquos Powerpacks are currently selling for around that price mdash so presumably itrsquos a bit lower but thatrsquos just a guess Other estimates put Teslarsquos battery packs at a cost of 200kWh right nownbspp
