An end to exploding lithion-ion batteries (?)

The next article I read in the scientific journal. This is about the development of lithium-ion battery that regularly came into the news because they sometimes overheated and exploded as a result. For example, the batteries of smartphones, laptops and cars sometimes caught fire. Fortunately, the development in this area does not stand still, hence the article below.

Nicola Tesla had made a discovery at the beginning of the 20th century. This made it possible to generate very cheap energy that was also very environmentally friendly and sustainable. In principle, batteries were almost unnecessary. How this system works I do not want to explain here. But this technique was a thorn in the eyes of those who owned oil fields because the oil was virtually superfluous. These people had a lot of power then and still and especially the OPEC countries. On January 7, he died under suspicious circumstances after he was often opposed.
But he was also working on a death-ray that could have been a reason.
He may have been killed, but there's no evidence of this, but given what he was working on, it's still plausible. https://tvvisie.be/inhoud/belgie/onderzoek-naar-de-dood-van-nikola-tesla-op-discovery_88524/ Look nr. 10 2018
No more explosions with this lithium battery.
By covering the lithium in batteries with ceramic material, they provide ten times as much energy as the current #lithium -ion batteries. Bonus,: they don't catch fire.
From smartphones and laptops to cars and planes, lithium-ion batteries are everywhere. But while they supply a lot of energy, these rechargeable batteries are far from perfect. For example, one still wants in #brand fly. Researcher at the University of Michigan have taken a step in the right direction to solve this problem.

But first it is useful to know that the first (liquid) lithium batteries on the market were on fire more often than the current lithium-ion batteries, which formed a lot of dendrites: accumulations of lithium atoms that caused too much energy in one place came together. Due to the fact that the lithium is embedded in carbon in the current batteries, the formation of dendrites is significantly reduced. Unfortunately, modern lithium-ion batteries deliver less power.

The American researchers come up with a different solution: ceramics. A layer of this material on the lithium acts as an electrolyte, the medium between the two ends of the battery. Due to the ceramic material, there is no accumulation of lithium atoms. And one more plus: in theory, this battery has a ten times greater capacity than the lithium batteries we use now.

There is unfortunately no question of large-scale production of ceramic lithium batteries, but perhaps in the future we will all be walking around with a 'ceramic' phone. KK
