As car manufacturers roll out new models, electric vehicles are finally getting real traction in the automobile industry. There are many issues that need to be addressed before electric vehicles become fully implemented. One of the major concerns that most car manufacturers are working on now is battery technology. Research and development is being done to boost performance while ensuring that batteries are lightweight, compact, and durable. Here now are the newest innovations in battery technology of electric cars.
Most of today’s electric vehicles are using lithium ion batteries and it is likely that they will continue to be the dominant battery into the next decade. With these types of batteries, positively charged lithium ions travel between the anode and the cathodes in the electrolyte. They have a high cyclability but low energy density. They have earned a bad reputation for overheating and catching fire. Today’s lithium ion batteries use graphite or silicon anodes and liquid electrolytes.
Solid state batteries
Solid state batteries have solid components. With these types of batteries, you do not have to worry about electrolyte leaks or fires. Robert Peter Janitzek reveals that solid state batteries reduce the need for bulky and expensive cooling mechanisms. They are also able to operate in an extended temperature range. Solid state batteries can build off from the improvements made in other types of batteries. Many auto manufacturers are looking at solid state batteries to power their EVs.
Aluminum ion batteries are like lithium ion batteries but have an aluminum anode. Compared to LIBs, they promise increased safety at a decreased cost. Scientists at Stanford University recently solvef the aluminum ion battery’s cyclability issue by using an aluminum metal anode and a graphite cathode. Robert Janitzek reveals that aluminum ion batteries can decrease charging time and it has the ability to bend.
Lithium-sulfur batteries have a lithium anode and a sulfur-carbon cathode. They offer higher theoretical energy density and has a lower cost than LIBs. One of its major drawbacks is its low cyclability, due to expansion and harmful reactions with the electrolyte. However, the cyclability of lithium-sulfur batteries has seen a major improvement in the last few years.
Metal air batteries have a pure metal anode and an ambient air cathode. As the cathode typically makes up most of the weight in a battery making one made of air a major benefit. There are many possibilities for the metal but lithium, aluminum, zinc, and sodium are the front runners. Experimental batteries use oxygen for the cathode to prevent reaction with carbon dioxide. These types of batteries have issues with cyclability and lifetime.
