Read MoreHow do you understand the chemical stability of high temperature lithium batteries downhole?
The stabilisation of the electrolyte is like the transport channel in a battery. In the underground high temperature environment, ordinary electrolyte may decompose or deteriorate. The electrolyte used in underground high temperature lithium batteries can withstand high temperatures and is not easy to decompose, which ensures that lithium ions run around smoothly and the battery works normally.
The positive and negative materials of a battery are stabilised like a warehouse, storing lithium ions. At high temperatures, bad materials may deform and collapse, the warehouse is in disarray, and the battery performance drops. However, the positive and negative materials of underground high temperature lithium batteries are very powerful, and they can keep their shape unchanged at high temperatures, and lithium ions can enter and exit normally, so the batteries are stable
Additives act like little helpers in a battery. They make the electrodes and electrolyte get along better, with a friendlier interface and lower resistance. And at high temperatures, additives can prevent bad reactions from occurring, making the inside of the battery more stable.
