The competition for lithium-ion batteries is heating up in a good way.
And then there are lithium-metal solid-state batteries which promise to be safer, faster charging and last longer than existing lithium-ion technology.
The State of Aluminium-Sulphur Batteries
This type of battery has been around for a while but the main shortcoming of the technology has been durability. The batteries using ambient temperature ionic liquid electrolytes form dendrites over time that interfere with the flow of electrons between the anodes. The results are short circuits. The cure appears to be raising the operating temperature of the battery and switching out the electrolyte. At 110 Celsius (230 Fahrenheit) degrees this new version of the aluminum-sulphur battery doesn’t form dendrites.
