Lithium batteries have come to the bottleneck of development, but currently there is no suitable battery to replacelithium batteries. This is actually the same as Edison’s invention of the electric light. The electric light was invented a long time ago, but what materials can be used for durability, Edison can only one by one. I tried

The principle is different, let’s talk about lithium batteries and lithium ion batteries (polymers are also lithium ion batteries). Lithium batteries are a type of negative electrode material made of lithium metal or lithium alloy. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high
