Nowadays, lithium ion battery is more and more used by the
portable power market, such as the mobile phones, blue-tooth, wearable smart
watch,electrical bicycles, E-cars and so on. Because its a high efficiency
rechargeable battery with high power in small size and weight, lithium ion
battery especially the lipo battery is spreading the digital market
quickly in recent years. However, It’s cycle life is only 300 times~500 times,
not very durable, the reason is that lithium ion battery is using graphite as
the anode material, but the graphite can degrade as time goes, which means a
degradation of the battery anode and battery life.
Recently,a new type durable rechargeable li-ion battery called
mushroom battery was developed by scientists in California University. This
lithium ion battery has better durability than all other existing lithium
batteries with great ribbon like micro hole structure from mushroom, and
more easy to be produced.

Researchers heat the mushrooms to be 500 degrees
temperature, so it generates a carbon nano strap structure, then with a
new 1100 degrees heating process, finally the carbon nano strap becomes
multiple holes structure items, which can be great material for lithium
ion battery anode to bring a perfect durability performance.
The multiple hole nano structure is very important for a lithium
ion battery, because the bigger hole space for energy transfer and moving
brings longer cycle life and slower degradation.
“We can expect a more durable Lithium ion
polymer battery in our mobile phones in coming future
if we continue to activate this structure and improve it” Said one of the
researchers Campbell.
