Typology of Battery Cells - From Liquid to Solid Electrolytes

Area of Science:

• Electrochemistry
• Materials Science
• Energy Storage

Background:

• Battery research features numerous battery names reflecting historical focus (e.g., lithium-ion, solid-state).
• All batteries share a fundamental structure: two electrode layers and an electrolyte layer.
• Hybridized battery concepts are increasing, necessitating a clear classification system.

Purpose of the Study:

• To propose a systematic and universal naming system for battery cells.
• To provide a method for identifying battery type and chemistry at a glance.
• To aid in navigating the dynamic field of battery research.

Main Methods:

• A systematic typology based on the principal ion conduction mechanism of the electrolyte.
• Introduction of the universal cell naming system ^AAMXEB^CAM.
• Discussion of existing battery types and hybrid concepts.

Main Results:

• The proposed naming system, ^AAMXEB^CAM, categorizes batteries by anode active material (AAM), electrolyte type (X), and cathode active material (CAM).
• The electrolyte type (X) includes liquid (L), gel (G), plasticized polymer (PP), dry polymer (DP), solid (S), and hybrid (H).
• The classification is applicable to all battery cell chemistries, not limited to lithium-ion or solid-state.

Conclusions:

• The ^AAMXEB^CAM system offers a concise and universal approach to classifying battery cells.
• This typology facilitates a better understanding and overview of diverse and emerging battery technologies.
• The system is adaptable to the rapidly expanding field of battery research, including novel hybrid designs.
