A brief introduction to several common types of new energy batteries, their working principles, and development trends in the market:

Lithium-ion battery:

Working principle: Stores and releases electrical energy by embedding lithium ions between the positive and negative electrodes. Common positive electrode materials include lithium cobalt oxide and lithium manganese oxide, while the negative electrode material is usually graphite. Organic solvents are used as the electrolyte.

Development trend: Increase energy density, extend cycle life, reduce costs, and enhance safety.

Sodium-ion battery:

Working principle: Similar to lithium-ion batteries but uses sodium as the ion. Positive and negative electrode materials can be oxides, phosphates, etc. Organic solvents are used as the electrolyte.

Development trend: Increase energy density, enhance cycle life, and reduce costs.

Lithium titanate battery:

Working principle: Uses lithium titanate as the negative electrode material and lithium iron phosphate, etc., as the positive electrode material. The reaction between the positive and negative electrodes generates electrical energy. Organic solvents are used as the electrolyte.

Development trend: Improve fast charging and discharging performance, increase cycle life, and enhance low-temperature performance.

Solid-state battery:

Working principle: Uses a solid-state electrolyte instead of a traditional liquid electrolyte. Positive and negative electrode materials can be lithium titanate, sulfides, etc.

Development trend: Increase energy density, enhance cycle life, improve safety, and reduce costs.

Metal-air battery:

Working principle: Uses metals (such as zinc, aluminum) as the cathode and oxygen from the air as the anode to generate electrical energy through a chemical reaction between the metal and oxygen.

Development trend: Increase energy density, extend lifespan, and address issues related to metal corrosion and oxygen permeation.

Fuel cell:

Working principle: Generates electrical energy through the chemical reaction between hydrogen and oxygen, with water as the byproduct. Common types of fuel cells include proton exchange membrane fuel cells (PEMFC) and solid oxide fuel cells (SOFC).

Development trend: Increase efficiency, reduce costs, and improve durability.

Aluminum-ion battery:

Working principle: Stores and releases electrical energy by embedding and releasing aluminum ions between the positive and negative electrodes. The positive electrode material can be aluminum oxide or other oxides, while the negative electrode material is usually graphite.

Development trend: Increase energy density, reduce costs, and enhance safety.

Calcium-ion battery:

Working principle: Similar to lithium-ion batteries, uses calcium ions to store and release electrical energy between the positive and negative electrodes. Positive electrode materials can be calcium titanate materials, phosphates, etc., while the negative electrode material is usually graphite.

Development trend: Increase energy density, enhance cycle life, and reduce costs.

Sodium-sulfur battery:

Working principle: Uses sodium and sulfur compounds as the positive and negative electrode materials, respectively, and stores and releases electrical energy by moving sodium ions between the electrodes at high temperatures. Solid-state materials are used as the electrolyte.

Development trend: Lower operating temperatures, improve cycle life, and address safety issues.

Hydrogen-carbon battery:

Working principle: Uses hydrogen gas and solid-state carbon as the positive and negative electrode materials, respectively, to generate electrical energy through a chemical reaction at high temperatures. The reaction products are water and solid-state carbon.

Development trend: Increase energy density, lower operating temperatures, and improve cycle life.

Photovoltaic cell:
