Dalhousie University researchers have made a battery breakthrough that could potentially revolutionize the struggling electric vehicle sector. While battery electric vehicles or BEVs are expected to replace internal combustion engine (ICE) cars as the world’s primary mode of vehicular transportation, they are still a work in progress.
Using the University of Saskatchewan’s Canadian Light Source, Dalhousie University and University of Saskatchewan scientists have discovered a new type of battery that can retain 80% of its original capacity after 20,000 charging cycles or 8 million kilometers. With current U.S. regulations stating that electric vehicle batteries should retain at least 80% of their capacity after 8 years of use, the new ‘single-crystal electrode’ could significantly extend the lifespan of EV batteries.
The researchers kept the single-crystal electrode in a constant state of charging and discharging for more than 6 years at their lab in Halifax. Their findings indicated that the new material significantly outclasses lithium-ion battery chemistries which run for just 2,400 cycles (960,000) kilometers before their capacity starts to decline.
This single-crystal electrode battery could open the door to EV batteries that last significantly longer before they have to be replaced, cutting down maintenance and repair costs for the drivers as well as limiting the environmental impact of discontinued EV batteries.
Dalhousie University scientists found that while conventional batteries experience ‘severe microscopic damage’ which results in cracking and deterioration, the new single-crystal electrode had zero signs of microscopic damage due to regular mechanical stress. The scientists found that the single-crystal electrode looked essentially new after significant use, exhibiting a durability that could allow for longer-lasting electric cars.
The EV battery, undoubtedly the most important component in every electric car, has been subject to most of these research efforts to develop much more efficient and energy-dense batteries.
Manufacturers currently use lithium-ion battery packs to power electric cars but scientists are working on different battery chemistries that can hold more energy, discharge this energy more efficiently, and have limited risk of fire. Such innovations will be key to mitigating range anxiety, one of the largest battery and range-related barriers to electric vehicle adoption.
Furthermore, these superior battery chemistries could be repurposed into stationary storage once they begin their second, post-electric car life. Stationary storage facilities will be critical to widespread green energy adoption as they can be used to mitigate the innate intermittency of renewable energy sources such as solar and wind.
If these new fast-charging batteries are eventually commercialized, it would have a hugely positive impact on the market potential of numerous EV companies, such as Life Electric Vehicles Holdings Inc. (OTC: LFEV).
