Solid-state batteries for cars

September 19, 2024 By EarthWise Leave a Comment

Battery-powered electric vehicles have historically faced the challenges of limited driving range and long charging time.  In recent years, both of these limitations have been largely overcome for many if not most drivers.  Popular EVs on the market can go 300 miles and more on a charge and today’s fastest charging networks can add 200 miles of range in 20 minutes.  But many people want even more range and even faster charging.  Both of these things will happen in the not-too-distant future.

Multiple companies are working on solid-state batteries, which hold more energy in a given volume than current batteries.  The lithium-ion batteries that power today’s EVs (as well as our phones and computers) have a liquid or gel electrolyte.  Solid-state batteries use a solid ceramic or polymer electrolyte that provides higher energy density, faster charging times, and reduced fire risk as well.

Samsung announced that it will produce solid-state batteries for vehicles by 2027.  Toyota says it is on track to develop a solid-state battery by 2027 or 2028.  California-based QuantumScape has an agreement to supply solid-state batteries to Volkswagen for mass production.  Tesla has not said what it is doing with regard to solid-state batteries, but it is likely that it’s also pursuing the technology.

The upshot of all of this is that EV ranges are likely to increase dramatically over the next several years leading to the availability of vehicles that can go 600 miles or more on a charge.  Given that the cost of EVs is already rapidly becoming at least competitive with if not lower than that of gasoline-powered cars, the days of internal combustion are becoming numbered.

A Boom In Auto Battery Manufacturing | Earth Wise

June 24, 2022 By EarthWise Leave a Comment

A surge in automobile battery manufacturing

Nearly all automobile manufacturers are in a global race to build electric cars and trucks.  There is a rapidly growing need for the battery packs that power those vehicles and therefore manufacturers are in a race to build battery factories to address that need.

The latest battery plant announcement comes from Stellantis – the new company created in 2021 through the merger of Fiat Chrysler and Peugeot.  Stellantis aims to sell five million electric cars by 2030, which means they will need a lot of batteries.  They will be spending $2.5 billion in partnership with Samsung to build a battery factory in Kokomo, Indiana.  The facility is expected to create 1,400 jobs.  Stellantis already had announced that it would build a battery factory in Windsor, Ontario in partnership with LG Energy Solutions. 

They are not alone in their aggressive efforts on electric vehicle battery development.  Ford Motor is building two battery plants in Kentucky and a third one in Tennessee.   Ford has recently started production of its F-150 electric pickup truck which has attracted large numbers of pre-orders.  The gas-powered Ford F-150 has been the best-selling vehicle in America for years.

General Motors is opening a new battery production plant in Ohio this summer and has two others under construction in Tennessee and Michigan.   Hyundai plans to spend $5.5 billion on an electric vehicle and battery manufacturing facility near Savannah, Georgia that is expected to begin operations in 2025.

The auto industry has been struggling in recent times, but there is clearly a massive boom underway as the industry makes the transition from internal combustion engines to battery electric power.
