graphite anode

Third-party tests of GDI’s 100% silicon anodes show that they offer more than 30% energy density than graphite anodes, allowing for 15-minute rapid charging up to 80% state of charge (SOC) for hundreds of times back to back.

Scientists in the United States placed fast charging for lithium-ion batteries under the microscope, finding that charging at higher rates can quickly damage the structure of a graphite anode, causing capacity loss even after a small number of cycles. By identifying the mechanisms causing this performance loss, the group can help point future research in the right direction.

Epsilon Carbon has commissioned a new production facility to manufacture synthetic graphite anode materials for lithium-ion batteries. It plans to invest US$70 million over the next five years to increase the plant’s capacity to 50,000 tons.

Scientists in the United States have fabricated a working lithium-ion battery using a phosphorous-based anode. The batteries show significantly higher capacity than today’s lithium-ion tech, and could serve as a guideline for future design of high-performance anodes for Li-ion batteries.
