The world of plants and home electronics usually does not overlap. But a new device that combines electronics and biology is a major step toward a world where plants and computers are increasingly intertwined.

On July 8, Dongxu photoelectric, a liquid crystal glass substrate enterprise, released its graphene based lithium-ion battery product in Beijing, which is known as the world's first graphene based lithium-ion battery. Various media reported and praised it for accelerating the pace of graphene industrialization. However, my opinion on this product is that it has no impact and basically uses the technology of tool.

Graphene bubbles blow too much. I'm a battery guy. Try to answer the landlord's question. First of all, I can't make a conclusion that graphene is used in other directions. In the field of battery, especially in the direction of lithium battery, being a "graphene battery" basically belongs to bullshit (in this case, it doesn't include new batteries such as super capacitors and lithium sulfur, which may be more optimistic).

Conductive plastics or polymers are relatively new materials. Its predecessor is common in televisions and mobile phones based on organic light-emitting diodes (OLEDs). Different from metal based devices and circuits, the polymer is flexible, easy to mass production and biocompatible. The conductive plastic is made from the earth's rich elements (carbon, nitrogen and oxygen) and can also be made by "ink printing". Collins's material has two other important properties: it can transmit electronic and ionic signals, which are the main mode of transmission of neurons in the brain. These characteristics are also crucial for the materials in the battery.
