Navy researchers boost performance of Ni-Zn cells commensurate with Li-ion; safer alternative

Green Car Congress

With 3-D Zn, the battery provides an energy content and rechargeability that rival lithium-ion batteries while avoiding the safety issues that continue to plague lithium. The long-standing limitation that has prevented implementing Zn in next-generation batteries lies in its poor rechargeability due to dendrite formation.

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. —Prof. Haesun Park, Chung-Ang University, co-corresponding author.

Amorphous titanium dioxide nanotube anodes for sodium-ion batteries show ability to self-improve specific capacity

Green Car Congress

They attributed this as being likely due to the prohibitively large ionic radius of the sodium ion (1.02 Å) as compared to the Li ion (0.76 Å); insertion of Na ion therefore requires large distortion of the metal oxide lattice, which would require unacceptably elevated temperatures not realistic for the operation of batteries.
