Battery Pack(s) must be reinvented - the solution is a commercial solid state battery. Solid-state batteries will bring EV’s in hyper drive accelerating the demise of internal combustion motors.
Some of the red lines the EV’s industry is facing at the actual moment:
If the last point on this list can be address through a combination of AI and future transportation planning and regulations, it is still depending of the advance of new battery pack technologies. Battery packs in actual design are too expensive and heavy, beside the fact the charging time together with a relative limited mileage per single charge is setting potential buyers off.
In a nut shell: before the electric cars take over, the battery pack(s) must be reinvented in order to come in line with consumer demands and become a viable and reliable solution universal accepted.
At the time this article has been published, the main solution used in production of the battery banks is lithium ion battery type. The performance of this type of batteries has started to flatten; no major improvements are on the R&D pipelines for the near future. That triggers existing R&Ds to go after other sources, in order to better store electric power: the solid state batteries type.
Adoption of electric vehicles is already expected to fuel an exponential increase in lithium-ion batteries, the reigning replacement for the internal combustion engine. One of the latest reports in the industry specifies that electric busses and passenger cars are accounting for 44 gigawatt hours of lithium-ion battery demand in 2017—and by 2030 that demand is forecast to surge to over 1,500 gigawatt hours per year. That can be double in case the solid state batteries are coming in production and replace the lithium-ion type.
Solid State Batteries:
Solid State Batteries are reducing the risks of batteries bursting into flames and they do allow for thinner cells and smaller packs to fit underneath of the cars. They do reduce the overall car weight, improving the traveling distance on a single charge.
Solid State Batteries vs Lithium Ion batteries:
Lithium-ion technology uses a liquid electrolyte to shuttle ions between the anode and cathode to charge or discharge a battery. A solid-state battery, as the name suggests, replaces this liquid with a solid material such as ceramic, glass or a polymer.
Researchers also want to pair the solid electrolyte with a lithium metal anode to improve energy density and enable EVs to travel longer distances without stopping.
Some of the major players in this space:
For passenger cars, we should see prototypes in the early 2020s,” said Andreas Hintennach, head of battery research at Stuttgart, Germany-based Daimler.
China's Qingtao New Energy Research Institute will experiment with cars within two years and considers a commercial product possible by 2025.
Contemporary Amperex Technology Ltd., China's biggest cell-producer, includes solid-state in its advanced-battery research.
South Korea’s Samsung SDI Co., SK Innovation Co. and Hyundai Motor Co. said they're also involved in this technology.
Toyota has reached the most advanced state on this matter. The company is investing 1.5 trillion yen ($13.9 billion) in its battery business and has plans to commercialize solid-state technology by the early 2020s. They own the most number of patents in the industry related to solid state battery type, over 233 patents or applications concerning this technology.
Some of the most recent developments on US market:
Ionic Materials Inc., based in Woburn, Massachusetts, with Sun Microsystems co-founder Bill Joy and a venture-capital fund comprising automakers Renault SA, Nissan and Mitsubishi Motors Corp. as backers.
SolidEnergy Systems, an MIT spinoff also based in Woburn, expects to begin trials with EVs after 2021.
Solid Power, a Louisville, Colorado-based battery company, has had a development partnership with BMW AG since December 2017.
Tesla Motors is backed up by supplier Panasonic which continues researching solid-state technology.
