Tokyo University Scientists vastly improve capacity of sodium- and potassium-ion batteries

Electric Cars Report

Lithium-ion batteries (LIBs) are, by far, the most widely used type of rechargeable batteries, spanning numerous applications. Although LIBs deliver the best performance in many aspects when compared to other rechargeable batteries, they have their fair share of disadvantages.

Researchers use graphite positive electrodes in high-capacity rechargeable lithium/chlorine batteries

Green Car Congress

The high surface area and large pore volume of aCNS in the positive electrode facilitated NaCl or LiCl deposition and trapping of Cl 2 for reversible NaCl/Cl 2 or LiCl/Cl 2 redox reactions and battery discharge/charge cycling. This work could open up widely available, low-cost graphitic materials for high-capacity alkali metal/Cl 2 batteries.

New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. This layer is very important and is naturally formed by the reaction between the lithium and the electrolyte in the battery.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. Haesun Park, Chung-Ang University, co-corresponding author. —Prof.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.
