Tesla Dry Battery Domination Starts in 2020

Tesla cars have been able to last for one million miles but starting in 2020 the battery packs will be able to last for a million miles as well. Currently, the battery packs last for 300,000 to 500,000 miles. Most non-electric cars only can last 100,000 to 200,000 miles.

Tesla will start using battery domination starting in 2020 with significantly longer lasting and higher energy density batteries. This will enable Tesla to use a mix of better prices and higher performance to win electric cars, electric trucks and with electric taxis.

Tesla Will Be Ten Times Better on Robo-Taxi Asset Costs

Electric taxis operational costs will mainly be functions of the longevity of the car and the autonomy. Tesla will have million-mile battery packs and million-mile cars. The main asset will have five times the life of competing services. Tesla will also use post-lease cars which means another 50% reduction in the fleet costs.

Tesla completed the purchase of Maxwell Technologies which will give Tesla higher energy density batteries, lower costs for batteries, double battery life and will allow battery factories to have 16 times the production in the same space.

Those who are down on Tesla say that Tesla’s batteries are not that much better than other electric car companies. However, Tesla’s battery dominance will become more clear next year and then Tesla battery domination will grow as they increase energy density to double current levels around 2025

Tesla bought Maxwell Technologies for their dry battery technology. Maxwell has already proved 300 Wh/kg energy density is which 20-40% better than current Tesla batteries. Maxwell has a path with 15-25% improvement every 2-3 years. This should lead to 500 Wh/kg by 2027.

Tesla might be able to get 385 Wh/kg in batteries in 2020.

Tesla could reach $50 per kilowatt-hour with 500 Wh/kg. This would mean half the weight in batteries while producing the same level of energy as the best 250 Wh/kg batteries of today. This would mean $4000 instead of $12000 in batteries for an 80 kWh battery pack.

Maxwell had a 15-page investor presentation from January 16, 2019 from the 21st Annual Needham Growth Conference.

Solid State Batteries Can Compete on Energy Density But Are Six to Ten Years Away

Panasonic has said solid state batteries are ten years away. Volkswagen thinks they can get them by 2025. Fisker has delayed solid-state batteries from 2020 to 2022.

A small chinese battery company, Qing Tao (Kunshan) Energy Development Company, has a production line capable of producing 0.1 GWh solid-state batteries per year, which have an energy density of over 400 Wh/kg. This is enough for one thousand 100 kWh battery packs.

Tesla’s will be producing tens of GWh of batteries from multiple gigafactories.

There are a range of possible competing battery technologies but getting them working at all, and then out of the lab and then to the scale for millions of cars are huge challenges.

Other Dry Battery Research

Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new production process with the aim of efficient and environmentally friendly future battery production. They coat the electrodes of the energy storage cells with a dry film instead of liquid chemicals. This simplified process saves energy and eliminates toxic solvents. A Finnish company is currently successfully testing the new IWS technology in practice.

The Finnish battery company “BroadBit Batteries”, together with IWS, has commissioned a pilot plant in its Espoo factory, which coats electrodes with dry electrode material instead of wet pastes, as has been common in industry up to now. BroadBit uses it to produce new types of sodium ion batteries.
