Breakthrough battery charges in minutes and lasts thousands of cycles::‘Lithium metal anode batteries are considered the holy grail of batteries,’ researcher says
I’ll believe it when it ships. I’m genuinely optimistic that we can develop better batteries, but I’ve seen this story too many times before.
Those 90 stories you’ve seen generally did all ship. Just three decades ago lithium batteries stored about 80Wh per kg. These days it’s around 600Wh per kg and our progress has been particularly rapid lately.
Durability, safety and charge speeds have also all been improving. Oh and costs are coming down dramatically as well.
Ignore the “present” line on this chart as it’s an old one:
Feels like I’ve seen the same story in the last 20 years.
Battery news is pretty world changing so I understand whybit gets the same kind of attention miracle health advancements get. Unfortunately the hardest part remains making a commercially viable product but that said even finding new techniques that may not make it to market still advance the field further and expand our understanding.
I mean, so does a capacitor…
Capacitors don’t store enough power. They work well in trains where they can be charged continuously with overhead power lines/etc, and a lot of battery EVs have a small capacitor as part of their regen braking system… but if you want to actually store a large amount of power capacitors can’t do it (yet?).
That’s the point. It’s easy to charge a battery in minutes if it’s small enough

Fast cycling of lithium metal in solid-state batteries by constriction-susceptible anode materials - https://www.nature.com/articles/s41563-023-01722-x
Abstract
Interface reaction between lithium (Li) and materials at the anode is not well understood in an all-solid environment. This paper unveils a new phenomenon of constriction susceptibility for materials at such an interface, the utilization of which helps facilitate the design of an active three-dimensional scaffold to host rapid plating and stripping of a significant amount of a thick Li metal layer. Here we focus on the well-known anode material silicon (Si) to demonstrate that, rather than strong Li–Si alloying at the conventional solid–liquid interface, the lithiation reaction of micrometre-sized Si can be significantly constricted at the solid–solid interface so that it occurs only at thin surface sites of Si particles due to a reaction-induced, diffusion-limiting process. The dynamic interaction between surface lithiation and Li plating of a family of anode materials, as predicted by our constrained ensemble computational approach and represented by Si, silver (Ag) and alloys of magnesium (Mg), can thus more homogeneously distribute current densities for the rapid cycling of Li metal at high areal capacity, which is important in regard to solid-state battery application.
We’ll have a battery that will be thousands of times more energy dense that what we have today. The tech industry will make those the size of a rice grain so we can have thinner products and the exact same battery life of electronics today. 😑
