Okay, I need to write a professional Korean Wikipedia-style markdown document about LFP batteries based on the categories and keywords. Let me by understanding the structure and requirements.

First, the document should have a clear H1 title. The title provided is "LFP 배터리", so that's straightforward., the introduction section should give an overview of what LFP batteries are. I should their full name, Lithium Iron Phosphate, and their basic structure, like the cathode material. Also, highlight their key features such as safety, stability, and longevity compared to other lithium-ion batteries.

Moving on to the detailed sections. The user mentioned using H2 and H3 headers. Possible H2 sections could be 원리 및 구조 (Principle and Structure), 특성 및 장점 (Characteristics and Advantages), 주요 응용 분야 (Main Applications), 단점 및 한계 (Disadvantages and Limitations), 그리고 최근 기술 동향 (Recent Technology Trends). Each of these H2 sections can have H3 subsections if needed.

Under 원리 및 구조, I need to explain the chemical composition, the olivine structure, and the electrochemical process during charging and discharging. Maybe include a simple reaction formula here. Also, compare the cathode materials with other types like NMC or LCO.

For 특성 및 장점, list safety, thermal stability, cycle life, cost, and environmental aspects. Each of these can be H3 subheadings. For example, safety can explain why LFP is less prone to thermal runaway. Cycle life can mention the number of cycles and capacity retention.

주요 응용 분야 should cover electric vehicles, energy storage systems, portable electronics, and maybe industrial applications. Each application can have a brief explanation of why LFP is suitable there.

단점 및 한계 might include lower energy density, voltage limitations, self-discharge rate, and cold temperature performance. Explain each with technical details but keep it understandable.

최근 기술 동향 could discuss nanotechnology, silicon anodes, solid-state batteries, and recycling efforts. Mention recent advancements and their impact.

I need to ensure the information is accurate and objective. I should check some facts about LFP batteries, like typical voltage (around 3.2V), energy density compared to other chemistries, and cycle life numbers (maybe 2000+ cycles). Also, mention companies using LFP, like Tesla or BYD.

Use markdown syntax properly: headers, lists, emphasis. For technical terms, provide simple explanations. For example, when mentioning "열폭주 (thermal runaway)", explain it's a condition where increasing temperature causes further temperature rise, leading to potential fires.

Include a 참고 자료 section at the end with sources like research papers, manufacturer websites, or industry reports. Use Korean sources if possible, but if not, general ones are okay.

Check the length: aim for at least 800 characters. Since Korean uses more characters per word, this should be manageable. Make sure each section is sufficiently detailed but not overly technical. Avoid fluff, focus on key points.

Potential issues to watch for: making sure the technical terms are correctly translated and explained. Also, ensuring that the flow between sections is logical. Maybe start with the introduction, then structure, then pros and cons, applications, trends, and references.

Need to verify some data points. For example, LFP's nominal voltage is about 3.2V, which is lower than NMC's 3.7V. Energy density is lower, around 90-120 Wh/kg compared to NMC's 150-200. Cycle life is 2000-3000 cycles, which is higher. Safety aspects are due to the strong P-O bond in the phosphate structure, making it more stable.

Also, mention that LFP batteries are used in Tesla's standard range vehicles and energy storage systems like BYD's products. They are preferred for applications where longevity and safety are more critical than energy density.

In the disadvantages, besides lower energy density, the voltage plateau might make it harder to estimate state of charge. Self-discharge rate is higher than some other batteries, affecting long-term storage.

In recent trends, nanotechnology improves conductivity, silicon anodes increase capacity, solid-state electrolytes enhance safety, and recycling initiatives address sustainability.

Make sure all these points are covered in the respective sections. Use bullet points where appropriate, maybe tables to compare energy densities or cycle lives. But since the user didn't specify tables, maybe just mention them in text.

Check for any markdown errors, like proper header syntax (#, ##, ###), list formatting, and code blocks if needed (though probably not here). Also, ensure that the document is in Korean, using appropriate terminology.

Alright, putting it all together now. Start with the title, then introduction, followed by each section as outlined. Keep paragraphs concise, use subheaders for clarity, and end with references. Make sure the language is professional yet accessible, avoiding overly complex sentences.
