This answer is: Web24 de out. de 2011 · However, in areas like stationary energy storage, weight is less of an issue, and sodium-ion batteries could find a wide range of applications. “ The big concerns for stationary energy storage are cost, performance and safety, and sodium-ion batteries would theoretically perform well on all of those measures,” Johnson explained. WebSodium ions A marked and rapid increase in the Na ion transport across the plasma membrane into a nerve or muscle cell, via the Na ion channel, causes a depolarisation of the membrane that initiates a transient flux of electrical activity along the nerve or muscle (that is, an action potential) (Chapters 13 and 14).
