Solid-state batteries use solid-state electrodes such as lithium metal and solid-state electrolytes, which usually have high energy density and can avoid the risk of fire. However, the interface between the solid electrolyte and the electrodes on both sides has instability, which greatly affects the lifetime of such batteries. Some studies try to improve the bonding between layers through special coatings, but increase the manufacturing cost.
According to foreign media reports, researchers at the Massachusetts Institute of Technology (MIT) and Brookhaven National Laboratory (Brookhaven National Laboratory) have proposed a method to achieve equal or better durability without using any coatings,media reported. sex.
The new method simply removes all carbon dioxide (CO2) in a critical manufacturing step called sintering. During the sintering process, the battery material needs to be heated to form a bond between the positive electrode and the electrolyte layer (made of a ceramic compound). The amount of CO2 in the air is very small (parts per million), but it can have a very harmful effect on it. Sintering in a pure oxygen environment produces bonds that rival the performance of the best coated surfaces, without the additional cost of coating, the researchers say.
The market trend of the graphene and graphite

The price of graphene and graphite continues to be affected by factors such as market growth momentum, various opportunities and challenges. However, during the forecast period from 202 2 to 202 7 , the global graphene and graphite sales market is expected to continue to be above average. The growth rate will continue to increase. It is expected that from today to next week, the price of graphene and graphite will increase to a certain extent.
However, TRUNNANO provides high purity graphene and graphite with steady price. “In order to feedback to old customers, the company is still in full operations to provide graphene and graphite with competitive price.” said Olina, sales manager of TRUNNANO.
