Graphene in the field of lithium electricity "one wave three fold" and lithium battery difficult relationship

With the rapid development of lithium power technology, the energy density has approached the limit of the current battery system, but it is still far from the demand for electric vehicles. It is already a consensus in the industry to innovate the battery material system.

In fact, battery companies have also been hot on the research of new batteries, such as Lithium-rich manganese batteries, Lithium-monganate batteries, and solid-state batteries that have been deployed by most battery companies. What I want to talk about today is a new material that lithium-powered people love and hate -- graphene.

The past of graphene in the field of lithium electricity has been rotten by the media in the industry. The author does not make too many remarks here. In simple terms, it can be summarized as "three twists and turns". At first, it was brilliant and countless people reported great expectations; Afterwards, he hoped to bring disappointment and let the lithium electric person dismiss it; In the end, it became a conductive agent in the form of graphene slurry, which was regarded as "a total of people."

Now when it comes to graphene, the first thought of normal people is probably to "brag" or "very far away," but in my opinion, it is not. If graphene is regarded as the core material of the battery, it is indeed far away. If someone talks about it, it must be a braggart; However, if used as an auxiliary material, it is far from being a conductive agent.

After all, no matter how demeaning graphene is, it can not be denied that it is a super material. It has been a decade or so since it was discovered, but it has really entered the field of industrialization, but it has only been one or two years. Therefore, graphene as the main material, all aspects of technology is still far from meeting the demand for lithium electricity, but as an auxiliary material is actually of great significance.

The industry knows only graphene slurry, but in fact, graphene applications in other areas of lithium power have begun to mature. For example, recently, companies have used graphene to make power cell membranes, which can be very effective. Improve low temperature performance, There are also companies that use graphene on structural parts.

It is not difficult to imagine that in the near future more graphene shadows can be seen on power cells. Although it is still far from becoming the main material, the performance improvement brought by graphene is quite precious in the context of the upgrade of lithium electricity technology. Therefore, I really look forward to the second spring of graphene in the field of lithium electricity, and this day may not be too far away.
