An international team of engineers and materials scientists has developed a lithium-sulfur battery that retains 80% of its charge capacity after 25,000 cycles, a significant improvement over conventional lithium-ion batteries, which typically degrade after about 1,000 cycles. This advancement is detailed in a study published in the journal Nature. The researchers utilized a solid electrode made from a glass-like mixture of sulfur, boron, lithium, phosphorus, and iodine. This innovative composition enhances ion diffusion and electron movement, allowing for quicker charging and better performance at high temperatures. Despite these advancements, the team acknowledges the need for further research to improve the battery's energy density and explore alternative materials to optimize weight and efficiency. The findings represent a promising step toward more durable and efficient battery technologies.

7 commentsThank you for your submission of proposed new revolutionary battery technology. Your new technology claims to be superior to existing lithium-ion technology and is just around the corner from taking over the world. Unfortunately your technology will likely fail, because:
[ ] it is impractical to manufacture at scale.
[ ] it will be too expensive for users.
[ ] it suffers from too few recharge cycles.
[ ] it is incapable of delivering current at sufficient levels.
[ ] it lacks thermal stability at low or high temperatures.
[x] it lacks the energy density to make it sufficiently portable.
[ ] it has too short of a lifetime.
[ ] its charge rate is too slow.
[ ] its materials are too toxic.
[ ] it is too likely to catch fire or explode.
[ ] it is too minimal of a step forward for anybody to care.
[ ] this was already done 20 years ago and didn't work then.
[ ] by this time it ships li-ion advances will match it.
[ ] your claims are lies.

Focusing on just 1, e.g. cycles doesn't give you the whole picture.
1. What is the capacity per $?
2. What is the capacity per kg?
3. What is the capacity per unit of volume?
4. Ease of disposal and recycling
5. Charge and discharge rates.
6. Safety.
7. Viable to produce commercially en masse?
There are just off the top of my head, and not necessarily in that order. The priority will vary depending on your use case.
LI-S batteries have significantly more capacity than commercial Li-[x] batteries of the same weight, but the big weakness until now has been that they have terrible durability.
Even people who can deal with the slower speeds after a few years of owning a phone get driven crazy by having to charge it often, I’d say it’s a big driver if not the biggest to buy a new phone.
Operating temperature range and cycle endurance were some primary barriers, and this seems promising, but ...
"The researchers suggest more work is required to improve the energy density and perhaps to find other materials to use for the mix to ensure a low-weight battery."
ok, nevermind.
