Monash University researchers in Australia have developed a new lithium-sulfur battery design that requires less lithium but provides more energy per unit volume (high energy density). Besides, the battery also has a longer lifespan and can be produced at half the price of today’s popular lithium-ion battery technology.
New lithium-sulfur battery design
For the new Li-S battery configuration, the researchers coated the lithium foil anode with a nanoporous polymer, allowing lithium ions to move through it, while also protecting the anode from corrosive sulfur compounds. trail.
This new polymer material has pores less than one nanometer in size, allowing lithium ions to move freely while blocking other chemicals that could attack the lithium. This polymer coating also acts as a support for the lithium and helps it charge and discharge continuously.
With a nanoporous polymer coating, the new Li-S battery design can maintain capacity with an improved charge count of 275 cycles. In particular, the new design also helps reduce the amount of lithium needed to produce batteries, without the need for nickel, cobalt or other minerals. Helps reduce product costs and supports environmental protection.
Through this research, it can be seen that the development of Li-S batteries can bring positive breakthroughs to energy storage systems. Aiming for more widespread application of Li-S batteries in life.
However, to widely develop this type of battery and put it into commercial and industrial projects, researchers will need to improve the existing limitations on the battery. Therefore, up to now, lithium-ion batteries are still the most popular technology.
