The new water -lithium battery uses a new type of polymer coating. It has special drainability. After applying it to the electrode, the molecules cannot be close to the electrode surface. After the first charging, the gel is decomposed into a stable interface, and the electrode and electrolyte areolate areolate to prevent the water molecules from being decomposed under the working voltage. This technology not only improves the energy storage and charging and discharge performance of the battery, but also completely avoids the risk of organic solvents electrolyte.

　　Although the working voltage of the new battery has reached the basic business level, compared with the current lithium -ion battery, there are many places that need to be improved. For example, the cost of zinc battery material is relatively high, and the charge and discharge can only reach 50 to 100 times. However, it is undeniable that it has important reference significance for battery technologies such as sodium ion batteries, lithium sulfur batteries, zinc and magnesium multi -ion batteries, as well as electroplating and electrochemical synthesis.

　　At present, the direction of the development of lithium battery technology is mainly to continuously improve energy density on the basis of ensuring the safety and cyclicity of batteries. In the traditional 3C field, due to the popularity of smartphones and tablets, the energy density of the original battery system cannot meet the requirements of battery life. It mainly increases energy density by improving battery design and increased battery voltage. However The limit can only increase by about 13-20%.

　　At present, although the energy density of the lithium battery prepared by the laboratory is 80%higher than the current traditional technology battery, it is far from industrialization. From equipment manufacturing research and development, to optimization of materials preparation technology, to the test session, each step must be improved as much as possible.
