They store considerably more energy than their lithium-ion cousins — in theory as much as six times the energy for a given weight. What's more, they can be made from cheap materials that are readily available around the world. A new design for these batteries which allows them to be charged and discharged hundreds of times without breaking down. We hope to have a commercial product ready in the next two to four years.

IBM has this week unveiled a new battery that relies on materials from seawater instead, with its early testing suggesting these components mightn't mean a compromise in performance, either. IBM’s battery doesn’t involve cobalt or nickel, materials that would be used in the cathode component of a typical lithium-ion battery. Its researchers have instead made use of three materials that can be extracted from seawater (though they haven't divulged the names of these ingredients), and added a new type of liquid electrolyte.

Combining two additives instead of one to facilitate the incorporation of lithium within capacitors: that is the solution proposed by researchers from l'Institut des matériaux Jean Rouxel (CNRS/Université de Nantes), in collaboration with Münster Electrochemical Energy Technology (University of Münster, Germany), in order to promote the low-cost, simple, and efficient development of the lithium-ion capacitors used to store electrical energy. This research, published in Advanced Energy Materials on 5 June 2019, will enable the mass marketing of these components.

Novel halogen conversion and intercalation into graphite boasts unprecedented battery capacity while maintaining excellent cyclability. Researchers Chongyin Yang and Ji Chen with co-workers under the direction of Chunsheng Wang at University of Maryland developed a novel graphite lithium ion battery that utilizes high density helper ion packing and a unique water-in-salt electrolyte to achieve a potential of over 4 volts in aqueous batteries.

Magnesium batteries are safe -- unlike traditional lithium ion batteries, they are not flammable or subject to exploding -- but until now their ability to store energy has been limited. Researchers have reported a new design for the battery cathode, drastically increasing the storage capacity and upending conventional wisdom that the magnesium-chloride bond must be broken before inserting magnesium into the host.

A new Li-ion battery technology developed by the US Army has piqued the interest of Jeff Dahn, Tesla’s main battery research partner. In the latest issue of the journal Nature, the CCDC Army Research Laboratory (ARL), which is an element of the U.S. Army, released a study demonstrating a new battery technology based on a new cathode chemistry. They claim that the chemistry is “completely free of transition metal and delivering unprecedented high capacity by reversibly storing Li-ion at high potential (~4.2 V).
