Lithium titanate technology and development direction

Lithium titanate ion battery why so far in our country’s energy industry and even the world’s energy sector applications are few and far between? There are 3 reasons for this.

1.lithium titanate material production lithium titanate material production in principle is not complicated. However, to be used as anode materials for lithium-ion batteries, not only must the material have a suitable specific surface area, particle size, density and electrochemical properties, etc., but also must be able to adapt to the production process of large-scale lithium-ion batteries. One of the reasons why lithium titanate material cannot be produced properly in many traditional lithium-ion production lines is that the material has a pH of 11 or 12 and is extremely hygroscopic.

2.Lithium titanate ion battery production in fact, the conventional lithium-ion battery production line will be used directly to produce lithium titanate ion battery products is not as simple as just replacing graphite with lithium titanate material. Because lithium titanate materials require much higher humidity than conventional lithium-ion battery production. In order to control the humidity, some preparation processes have to be adjusted accordingly to meet the special requirements of lithium titanate ion battery production. In addition, some production equipment should also be improved accordingly. If there are conditions, it is best to redesign a compact, compact, fully enclosed automated production line specifically for lithium-ion titanate battery products.

3.lithium-ion titanate battery pack and conventional lithium-ion batteries are different, the current domestic and foreign production of lithium-ion titanate batteries in the group into a period of application often see the soft pack of a single cell with trace amounts of gas appear. These gases are different from the gases that appear when fresh batteries are formed. The former can be removed through the battery manufacturing process. The latter, however, occurs during the use of the battery, or is difficult to prevent under current process conditions.
