I wish them the best, but there a probably at least a dozen similar companies with roughly similar claims with different underlying chemistries (flow batteries, etc.) and many more that haven&amp;#x27;t panned out for one reason or another.&lt;p&gt;People are most definitely trying to replace Li-ion but its not an easy thing to do in practice, even if simple enough on paper.</text><parent_chain><item><author>wesammikhail</author><text>It depends on the application.&lt;p&gt;There are plenty of applications where Li-ion is not the optimal solution. Li-ion is not the defacto standard for a myriad of reasons in various sectors. Certain massive installations have requirements that li-ion cannot work for.

Lithium ion are great, especially for electronics and EVs.  They are pretty good for grid scale, but we need other technologies there.  Currently the largest source of storage on the grid is pumped hydro (about 95% of storage on the grid) and it will continue to be the largest source of storage for a long time.</text><parent_chain><item><author>wesammikhail</author><text>It depends on the application.&lt;p&gt;There are plenty of applications where Li-ion is not the optimal solution.
