Our world of batteries is on the move. The cylindrical cells we used in flashlights and walkmans as kids, have morphed into new chemistries. But these cells still struggle to meet the demands of electric vehicles. Batteries are changing again in types and applications. Today we wonder, which direction will they take?
Changing Expectations Demand New Battery Standards
Electric vehicle sales are stagnating, and it is easy to understand why. California Globe ascribes this trend to insufficient charging stations, and lengthy charging times. Not to mention the cost of the batteries that replace gasoline engines.
Clearly, we need a change from lithium-on batteries that we embraced so willingly a decade or more ago. Solid state batteries are waiting in the wings already. They tempt us with promises of greater energy storage, improved safety, and more rapid charging too.
California Globe cites the example of the barnstorming Tesla Model 3. They confirm that this electric vehicle has a 342-mile driving range, using a 75-kilowatt-hour battery. But, as the new channel adds, that battery can only accept a charge equivalent to 12-miles per minute, even at a fast charging station.
Now, a gasoline-powered vehicle can take on board 150-200 miles per minute when topping up with fuel. It is also lighter and more spacious without an electric vehicle battery. Clearly, something must change in the world of batteries!
What Are the Goals for Next-Gen EV Batteries?
Consumers have become smarter about electric vehicles and their batteries, since the early, exciting days. They know what they are looking for, and that batteries are changing to meet these needs:
- Far shorter and faster charging. Expanded energy storage, leading to longer driving ranges.
- Significantly lower battery prices. Safer batteries that are more robust, and last longer too.
Solid state batteries may offer the best match to most of these requirements, overall. Although there are other exciting developments in the background, waiting in the wings. Only time will tell which one is the winner, for a while at least.
