The new battery is just one big crystal, meaning it's a more solid structure that is resistant to mechanical stress. Scientist Toby Bond says a new type of lithium-ion battery material called a single-crystal electrode can last decades, and be used in “second-life applications” such as storing wind and solar energy for the electrical grid.
Researchers have been testing a new type of lithium ion battery that uses single-crystal electrodes. Over several years, they’ve found that the technology could keep 80% of its capacity after 20,000 charge and discharge cycles. For reference, a conventional cell reaches 80% after about 2,400 cycles.
With its remarkable ability to withstand more than 20,000 charge-discharge cycles while retaining 80 percent capacity, a novel lithium-ion battery with a single crystal electrode has raised the bar for electric vehicle (EV) technology.
1 reply beneath your current threshold. The article notes that this new battery material is goood for 8m miles, which it notes is 8x a standard Li ion battery. That’s 625k miles! That’s already the equivalent of 40 years of driving the US daily average of 40 miles a day. More than good enough to outlast the rest of a typical car.
Even decreasing the temperature down to −20 °C, the capacity-retention of 97% is maintained after 130 cycles at 0.33 C, paving the way for the practical application of the low-temperature Li metal battery. The porous structure of MOF itself, as an effective ionic sieve, can selectively extract Li + and provide uniform Li + flux.
The researchers employed synchrotron x-ray diffraction to study the wear on the electrodes. One interesting result is that after use, the single-crystal electrode showed very little degradation. According to reports, the batteries are already in production and they expect to see them used more often in the near future.
