New battery breakthrough paves way for 100% silicon batteries with higher energy density
Not so fast What's the Tip, the expansion problem has been overcome by a number of patented tecnoledgies , some very clever Australian owned techs could put an end to expensive graphite BAMS before or even while they get the pilot plant going .
There are a quite a few companies some Australian that have excellent silicon Anode technology progressing very fast , silicon is 8 times cheaper than graphite and retains over 10 times more energy than graphite , electric vehicles have a range problem , silicon will provide cheaper , lighter and much more energy retention making 2000k range posible on a single charge,
LeydenJar Technologies, a Dutch spin-out of TNO, the Netherlands Organisation for applied scientific research, has developed a new anode which it believes will “drastically change the battery industry,” allowing lithium-ion batteries to be made from 100% silicon, boosting energy density by 70%.
With demand increasing across a variety of technology sectors for improved battery technology, recent innovation has been focused on transitioning away from the reliance on rare earth metals and carbon-based elements such as graphite. Conversely, increased battery performance and longevity is required as more and more sectors turn to batteries to participate in the global transition to cleaner energy.
Thus far, it has only been possible to produce anodes with a small amount of silicon due to the mechanical limitations of the material and the fact that anodes were primarily carbon based. However, as an anode material, silicon has ten times the capacity of carbon.
