Okay, I need to create a professional Wikipedia-style document about lithium-ion batteries in markdown format based on the given categories and keywords. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and possibly references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, emphasis, and code blocks if needed. The document should be at least 800 characters long.

The main topic is "리튬 이온 배터리" (Lithium-ion battery) under the categories Technology → Energy → Battery. Let me outline possible sections:

1. Introduction/Overview
2. Basic Principles of Lithium-ion Batteries
3. Working Principle
4. Components and Structure
5. History and Development
6. Types and Variants
7. Applications
8. Advantages and Disadvantages
9. Challenges and Future Prospects
10. Safety and Maintenance
11. References

I need to make sure each section is detailed enough. For example, under "Basic Principles," I can explain how lithium-ion batteries work, their components like anode, cathode, electrolyte, etc. In the history section, mention key developments over time.

For technical terms, like "anode" or "cathode," I should briefly explain them. Maybe use a table to compare different types of lithium-ion batteries (like LiCoO2, NMC, LFP). Also, include some safety information and common issues like thermal runaway.

I need to check for accuracy. For example, the working principle involves lithium ions moving between anode and cathode during charge/discharge. The components: graphite anode, metal oxide cathode (like LiCoO2), electrolyte solution, separator.

In applications, mention smartphones, electric vehicles, renewable energy storage. Advantages include high energy density, low self-discharge, no memory effect. Disadvantages: limited cycle life, safety risks if damaged, resource issues for materials like cobalt.

Challenges could be improving energy density, reducing costs, sustainability of materials. Future prospects might involve solid-state batteries or new chemistries.

Safety and maintenance: proper charging practices, avoiding overcharging/overdischarging, temperature control.

I should also include references to academic papers, industry reports, or reputable sources. Maybe a section for related documents like "리튬 이온 배터리의 발전 역사" or "배터리 기술 비교."

Now, structure the markdown with H1, H2, H3. Use bullet points and tables where appropriate. Make sure to keep paragraphs concise and avoid overly technical jargon without explanation.

Check for length: 800 characters is about 150-200 words. The example response provided earlier was longer, so I need to ensure the content is sufficiently detailed. Maybe expand each section with more details, examples, or data points.

Also, use code blocks if there are any technical specifications or formulas, but since this is a general overview, maybe not necessary unless discussing specific chemistry equations. However, for simplicity, perhaps avoid that unless needed.

Finally, proofread for clarity and flow, ensuring each section transitions smoothly and covers the key aspects of lithium-ion batteries.
