Liquid electrolytes have been key EV batteries for some time now and the lithium-ion formula is the most important component. There are a lot of different formulae that do various things such as the removal of toxic inputs from the supply chain, or reductions in weight, elimination of fire hazards, and cutting costs.

The ultimate goal is to combine all these improvements in one electrolyte, but solid state or semi solid state batteries are appearing before that goal can be achieved and they promise to revolutionize the battery market. But, getting the electrons to move about within a solid is difficult at best. And that’s where Zwitterions come in.

One of the new battery technologies is graphene aluminum-ion battery which is designed specifically with rapid charging in mind. Graphene aluminum-ion batteries avoid the use of lithium and copper, instead using aluminum substrates and a newly developed chloride-free electrolyte. This enables cost and weight reduction, improved safety risks, and eliminates the need for thermal management system. The battery has similar performance characteristics as lithium titanate oxide cells, but can be produced at a much lower cost

The technology works by making atomic sized holes in the graphene, which allows the aluminum ions to penetrate and be held in the graphene to make a higher energy density, thus enabling them to outperform standard lithium batteries.

In modern life, thousands of products (ranging from mobile phones to missiles, or fertilizer even) depend on a few critical minerals such as copper, cerium, rare earth elements and potash. Governments around the world consider these essential to their economy and national security, and their supply chains can be disrupted by geopolitical tensions, extreme weather, or trade restrictions.

For instance, in 2026, the U.S. critical minerals list include 60 minerals that companies in defense, agriculture, power, mining, and other industry sectors, need to get their jobs done. But spiking demand, restricted access, and rising prices can make it challenging to get these minerals

CATL unveiled a new sodium-ion battery for energy storage at the ESIE 2026 show in Beijing, in April. The show is the 14^th Energy Storage International Conference and Expo (ESIE). ESIE was born alongside the development of China’s energy storage industry and serves as a key communication and cooperation platform in the energy storage field.

CATL’s new battery expands its sodium-ion lineup beyond passenger cars, commercial vehicles, and auxiliary power, into utility-scale and commercial storage.
