Calcium-ion battery

A battery shuttling divalent Ca²⁺ ions, attractive because calcium is abundant and its metal sits only about 0.17 V above lithium’s potential while carrying two charges per atom. Practical cells remain elusive: calcium metal passivates in most electrolytes, reversible plating at room temperature was first shown in 2018, and Ca²⁺ moves slowly through host lattices.

Abbreviation
Ca-ion

Example

Other and emerging chemistries: an example situation

Two chemistries can meet the same energy target with different voltage windows and charge termination.

Read Calcium-ion battery alongside Intercalation in this context. Lithium inserting into, and leaving, the host structure of an electrode material — between graphite layers, for example — without destroying it.

Use in Lemonergy

Do not carry lithium-ion assumptions into every chemistry.

This is a reference concept. No executable Lemonergy block has been verified for this term.
