Recently, researchers from Pennsylvania State University have developed a new type of lithium-ion battery. The battery can be quickly charged at a higher temperature, and charging for 10 minutes can increase the range of 200 miles for electric vehicles. The battery may help reduce people's "mileage anxiety" for electric vehicles.
In order to meet people's travel needs, it is necessary to design electric vehicle batteries with extremely fast charging speed. However, fast charging may cause the battery to form lithium metal around the anode, seriously reducing battery life.
To solve this problem, the researchers designed a self-heating nickel-structured lithium-ion battery. To test the model, they used different cooling strategies to maintain a constant charging temperature, charging three lithium batteries at 40 ° C, 49 ° C, and 60 ° C, while performing control comparisons at 20 ° C. To confirm the presence of lithium plating, the researchers conducted an analysis after the battery was fully discharged.
The results show that the battery pre-heated to 60 ℃ can maintain extremely fast charging 1700 times, and the average charging temperature is 49 ℃ ~ 60 ℃, nor observed any lithium plating. The researchers also found that the increase in charging temperature shortened the cooling time required to maintain the initial temperature of the battery.
The researchers pointed out that this technology can be put into practical production. Although nickel foil increases the cost of each battery by 0.47%, but this design eliminates the current need for external heaters for lithium batteries, which actually reduces the battery's cost. Cost of production. (Author: Kochi)
