Seaweed Gives Scientists an Idea for Improved Batteries

Reuters reported that lithium-ion batteries have the potential to store ten times as much energy per kg of batteries if they were constructed with silicon anodes (compared to traditional li-ion batteries).

The market news is quoted as saying:

Lithium-ion battery anodes absorb lithium ions, expanding during that process, and then contract as the lithium ions leave them. Silicon anodes crack and malfunction during this process because they cannot handle repeated expansion and contraction. This is due to the fact that silicon is brittle.
