This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity\u2014a performance unmatched by other solid-state sodium batteries to date.<\/p>\n\n\n\n<p>Solid state batteries hold the promise of safer, cheaper, and longer lasting batteries. Sodium-ion chemistries are particularly promising because sodium is low-cost and abundant, as opposed to the lithium required for lithium-ion batteries, which is mined at a high environmental cost. The goal is to build batteries that can be used in large-scale grid energy storage applications, especially to store power generated by renewable energy sources to mitigate peak demand.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"300\" height=\"213\" src=\"https:\/\/csbattery.cn\/wp-content\/uploads\/2023\/01\/Battery-Illustration-1-1-300x213-2.jpg\" alt=\"\" class=\"wp-image-2185\"\/><\/figure>","protected":false},"excerpt":{"rendered":"<p>Une \u00e9quipe de chercheurs a con\u00e7u et fabriqu\u00e9 un nouveau conducteur sodium-ion pour les batteries sodium-ion \u00e0 l&#039;\u00e9tat solide qui est stable lorsqu&#039;il est incorpor\u00e9 dans des cathodes d&#039;oxyde \u00e0 haute tension.
