Part 5/11:
The innovation stems from CATL's use of a 3D honeycomb anode and a biomimetic electrolyte interface. The 3D honeycomb structure resembles a beehive, where hexagonal cells create ample space for lithium ions to move rapidly, significantly increasing the anode's surface area. This innovative design reduces stress during charging and creates a so-called "lithium ion superhighway" that can double the anode's specific capacity from 200 mAh to a groundbreaking 400 mAh. This promising application would allow electric vehicles to travel significantly greater distances on a single charge.
