Has a new type of electrolyte been developed that can increase the cycle life of lithium batteries by seven times?

According to foreign media reports, PNNL of the Northwest Pacific National Laboratory has developed a new battery electrolyte formula aimed at extending the battery life and battery capacity, thereby increasing the mileage of electric vehicles.

The new battery electrolyte can withstand 700 charge and discharge processes, which can increase the battery's service life by seven times, thus increasing the range of electric vehicles by two to three times. PNNL focuses on addressing the current challenges and technical challenges of lithium ion batteries.

Comments: The key to the improvement of battery energy density and cycle life lies in the optimization of the performance of positive materials. At present, major battery companies are stockpiling and developing new-generation battery technologies including solid-state batteries and graphene batteries. PNNL claims that the new electrolyte developed by PNNL can increase the service life of the battery by 7 times and the range of endurance by 2-3 times. This performance has exceeded the scope of conventional electrolytes, that is, it is not known whether the performance of the positive electrode material matched with it can keep up with it.
