NEW CHARGING ALGORITHM COULD DOUBLE LIFE OF LI-ION BATTERIES

Summary from the TLDR newsletter

A team of researchers from Berlin has developed a charging solution that makes lithium-ion batteries last much longer than they do now. It uses a pulsed current (PC) protocol that results in reduced mechanical stress and cracking in graphite particles within batteries and suppressed structural degradation in cathodes. Using PC charging can double the service life of commercial lithium-ion batteries with an 80% capacity retention. High-frequency pulsing with square-wave current produced the best results.
