With the promise of an autonomy of more than 800 km for a charge time of about one minute, with its long-awaited EMotion, Fisker wants to make Tesla and its “old” Lithium-Ion batteries more expensive. To achieve this, the startup must make a good lead on the key element in the autonomy of an electric vehicle and like any other consumer electronic gadget, its battery.
Henrik Fisker, but also Honda, BMW and Samsung, among others, rely on solid-state batteries to demodulate lithium-ion with a technology that will double the energy capacity of batteries.
The promise of energy density x 2.5
With more than 300 kg of batteries in a Tesla Model 3 and an energy density of 150 Wh/kg, the lithium-ion battery seems to reach its limits, both in the means of transport and on objects as common as our smartphones. The increase in the weight and size of the batteries will not be able to continue for a long time, which means that we can hardly hope for an improvement in the yield margin of these Li-Ion batteries and therefore we have to move on. NanoFlowcell offers an original solution with an electric car that literally fills up electricity with electrolyte carrying liquids. Others are working on graphene batteries, but in the shorter term, solid-state batteries have been the most common manufacturers in recent weeks. BMW, Honda made such announcements in December and Fisker may well be the first to market a new generation car based on this technology.
With the LMP (Lithium Metal Polymer) battery, the French Bolloré has shown the way, since it is this solid-state battery that has been equipping the Bluecar with the Parisian Autolib’ car-sharing service since December 2011. These cars travelled 160 million kilometres without battery lights making headlines as Tesla Model S did when they were launched. Bolloré announces a life expectancy of around 400,000 km, well above the Lithium-Ion batteries, even if the measurements made on the Tesla Model S after 80,000 km and 160,000 km are rather reassuring with 5% and 8% capacity reduction respectively.
Does Dr. Fabio Albano have the key?
For the time being, the solid-state battery still has to prove its real assets in the automobile, because if researchers estimate that it can rise to 800 or even 1,000 Wh/kg, Bolloré with 30kWh for 300 kg, its LMP batteries are still far from this density. Fisker builds on Dr. Fabio Albano’s work on solid state batteries. He was co-founder of Staki, a company specializing in these new generation batteries which was purchased by Dyson in 2015. Today, the researcher is Vice President of Battery Systems at Fisker Inc. and it is now up to him to keep Henrik Fisker’s promises with an energy density multiplied by 2.5 and a recharge time of around one minute, performances that could well make motorists’ last reluctance to go electric.
