What is the internal structure of high-temperature batteries?

Partition: The electrodes in high-temperature batteries are separated by porous electrical insulation partitions. The partition prevents direct contact between electrodes, which may lead to short circuits.

Electrode: The anode is usually made of lithium based materials, such as titanium acid (Li4Ti5O12), while the cathode is usually composed of lithium iron phosphate (LiFePO4) or lithium nickel manganese cobalt oxide (LiNiMnCoO2 or NMC).

Shell: The shell is usually made of durable materials that can withstand high temperatures and protect the battery from impacts, moisture, and other potential damage factors.

Electrolyte: The electrolyte in a high-temperature battery is the medium for ion transfer between the anode and cathode. It is usually composed of lithium salts dissolved in organic solvents or solid electrolytes.

Collector: The electrodes are connected to an external circuit through a collector. These collectors are usually made of conductive materials such as copper or aluminum, used to collect and distribute the current generated or supplied during battery operation.

Thermal management system: This system can include components such as radiators, heat pipes, or liquid cooling channels to dissipate excess heat and maintain optimal operating temperature.
