Development of a new type of battery using the world’s thinnest material could power our future devices with fast charge and discharge rates. Currently, we are using today’s lithium ion (Li-Ion) battery technology to power our laptops, tablets, cell phones, digital cameras, camcorders, and other portable electronic devices.  Current Li-Ion batteries mark today’s industry standards. R&D engineering researchers at Rensselaer Polytechnic Institute are taking Li-ion battery technology to the next level.  Intentionally blemished graphene paper is used to create quick-charging Lithium-ion batteries with a high power density.

Graphine Batteries

Graphene is an allotrope of carbon, which is structurally modified by bonding atoms together from the element in a different manner. Conventional Li-ion battery cells use carbon, metal oxide, and a lithium salt electrolyte in an organic solvent. Graphite is the most popular electrode material in batteries. The graphite is replaced with graphene paper, which has been photo-flashed and zapped with lasers to increase blemishes, countless cracks, pores, and other imperfections. This will transform the graphene paper and new battery design with high-rate capable anodes for lithium-ion batteries.

Graphine Li-Ion Battery

With the success of a high power density graphene Li-ion battery pack, holding large quantities of power, quickly holding charge and releasing this energy would bring a huge solution. Complex paring of Li-ion batteries and the use of super capacitors wouldn’t need to be extensively used in electric cars. A new graphene Li-ion battery pack with large power densities and energy densities would allow very fast charge and discharge rates. Imagine fast charging hybrid cars, all-electric cars, and solar powered vehicles becoming a reality.  Quick charging laptops, tablets, cell phones, cameras and mobile devices wouldn’t need to be recharged overnight. The world would be a very mobile place, without the need of an electrical outlet every few hours.
