　　Actually, we don’t follow the progress of some battery technology very often, but when it comes to groundbreaking breakthroughs, we will never miss it! This latest technology developed by engineers from Northwestern University claims that it can greatly increase the charging efficiency and capacity of lithium batteries by a factor of ten. Professor Harold Kung and his research team said that the key to this battery technology lies in the flow of lithium ions between graphene layers-the flow rate of ions in it directly affects the charging speed. In order to speed up the flow, they researched to change the arrangement of graphene into millions of honeycomb-shaped columns with a size of only 10 to 20 nm, creating a "quick shortcut" that is more suitable for lithium ion flow. Because of this, Professor Kung's team has also achieved a result of shortening the battery charging time by 1/10, but! This is only part of the charging speed.

　　These scientists have also increased the battery's power storage capacity. They researched to put a small group of silicon (Silicon) between the graphene layers to achieve the effect of increasing the density of lithium ions inside the battery. Thanks to the high ductility provided by graphene, such technological breakthroughs have also allowed more lithium ions to accumulate near the electrodes, and therefore solved the old problems caused by silicon expansion. As for the results? As powerful as the title, this battery will last for a full week after it is fully charged. Kung also said, "Now we are finally about to get the best performance in both aspects." Because of the advancement of silicon and technology, we have obtained a higher storage density, even if the silicon clusters (SiliconClusters) separate, it will not cause silicon to disappear. But what he said is "coming soon." So it can be seen that this technology still needs improvement-the greatly improved charging speed and battery capacity will cause the efficiency to drop sharply after 150 recharges. But Kung also pointed out that increasing the battery's charge retention (Charge Retention) capability will be enough to make up for this shortcoming-"Even if the performance of the number of charges is still maintained for 150 times, the life span can reach one year or more, let alone the battery after that. It still has five times the efficiency of existing lithium batteries.” Kung said in a BBC report. Reference sources will be able to see more in-depth technical details.
