Solid-state battery is a battery technology that uses solid electrodes and solid electrolytes.
Traditional lithium-ion batteries include four components: positive electrode, negative electrode, electrolyte, and separator, and the core difference between solid-state batteries and liquid lithium batteries is that solid-state electrolytes replace separators and electrolytes. Conventional liquid lithium-ion batteries use a liquid electrolyte as an ion migration channel, and a separator separates the positive and negative electrodes to prevent short circuits.
Solid-state battery is a new type of battery technology, but the basic principle is the same as that of liquid batteries, which is still a "rocking chair battery", that is, charged ions move back and forth between the positive electrode and the negative electrode to achieve the charging and discharging process, so the positive and negative electrodes of the solid-state battery have not changed compared with the liquid battery, but the electrolyte used to conduct ions in the liquid battery and the separator that isolates the positive and negative electrodes to prevent internal short circuits can be replaced by the solid electrolyte, and the migration site of ions is transferred from the electrolyte to the solid electrolyte, and at the same time plays the role of isolating the electrode.
Liquid lithium-ion battery electrolytes are flammable and present a risk of thermal runaway. The solid-state battery electrolyte is non-flammable and non-explosive; High mechanical strength can inhibit the growth of lithium dendrites, no electrolyte leakage is not easy to cause short circuit; There is no problem with electrolyte leakage.
At present, lithium-ion batteries can reach 230-300 Wh/kg (which is close to the theoretical limit of 350Wh/kg), compared to the theoretical limit energy density of solid-state batteries of 700 Wh/kg, and in general, solid-state batteries have a much better energy density than liquid lithium-ion batteries.
1. Solid-state batteries use solid-state electrolytes to replace the separator and electrolyte of liquid batteries, and the distance between the positive and negative electrodes can be shortened to only a few to a dozen microns, thereby greatly reducing the thickness of the battery.
2. The solid-state battery can simplify the packaging and cooling system, and the inside of the cell is a series structure, which further reduces the weight of the battery in a limited space, and the volume energy density can be increased by more than 70% compared with the liquid lithium-ion battery (graphite anode).
Although the solid-state battery industry is in its infancy, it represents the development trend of future batteries. At present, many countries are planning solid-state battery mass production technology, especially China, which has the largest penetration rate of new energy vehicles. They have achieved mass production of semi-solid-state batteries and are at the forefront of solid-state battery technology!
Solid-state batteries have so many advantages. Will they be used in laptop batteries in the future? The answer is: Yes.
From smartphones to laptops, consumer electronics require compact, high-performance batteries. Solid-state batteries provide the necessary power density and safety, making them ideal for these devices. Reducing the risk of overheating and extending service life are additional advantages that appeal to tech-savvy consumers.
We firmly believe that in the near future, we will definitely be able to use laptops with solid-state batteries!
