2024 年风电招标量同比增长 90%，预计 2025 年行业将进入密集交付期，上游制造环节盈利有望持续改善。目前，零部件环节在建工程增速转负、资本开支 已显著放缓，随着交付起量，此前资本开支所形成的固定成本将被有效摊薄，叠加部分环节有望提价，预计盈利将持续改善。此外，国内整机招标价格触底， 整机出口海外也持续有积极进展，预计整机环节盈利也有改善空间。

BC 电池背接触结构正面无遮挡。BC 电池的核心特点是将电池的正负两电极均集成在电池片的背面，而电池正面无任何栅线遮挡，能够最大限度地吸收太阳光，从而提高光电转换效率。BC 电池可以与 PERC、TOPCon、HJT 等电池技术叠加，通过优化设计和制造工艺，进一步提升光伏电池的性能和效率。

3 月九国电车销量 28.87 万辆，同比+26.2%，环比+63.6%，渗透率 25.5%，同比+4.7pct，环比+0.9pct，3 月在欧盟公布碳排考核目标放宽后同比保持强势增长，考虑 1-3 月欧洲九国注册量同比+24%，我们认为 25 年仍有机会实现 360 万以上销量，同比+21%。3 月主要国家销量表现：法国电车补贴退坡致销量短期承压，同比 -26%；德国电车销量同比+46%，主要系补贴提前退坡导致 24 年同期低基数；英国电车销量环比+262 %，同比+42%，同比强劲系 4 月新能源车车辆税对齐燃油车带来销量前置，环比大涨主要系新旧牌照替换周期惯性增长。

CVD 硅碳工艺的出现大幅提速硅负极的产业化，25 年硅负极预计在手机领域扩大渗透，也有望在动力场景实现 0-1，我们建议关注硅负极放量背景下，新工艺带来的产业链增量环节投资机会。CVD 法硅碳成新主流工艺，加速硅负极产业化，重塑竞争格局。1）球磨法向 CVD 法迭代：在硅的纳米化工艺上，CVD 法能将硅径粒精确控制在 10nm 以内，并实现均匀包覆，取代球磨法成为新一代主流工艺；2）CVD 硅碳相比硅氧优势扩大：目前 CVD 法硅碳/硅氧产品的克容量约 1800/1500mAh/g,且 CVD 硅碳可支持超 1000 次循环，并实现低于硅氧的膨胀水平。3）新工艺重塑格局：CVD 法下工艺、设备较硅氧大幅迭代，重塑先前硅氧的竞争格局，当前天目先导、兰溪致德、璞泰来、贝特瑞等在 CVD 硅碳进展领先。

随着我国新能源汽车产业快速发展，追求长续航和充电效率一直是行业发展的焦点。相比传统石墨负极，硅碳负极凭借超高理论比容量（约4200 mAh/g）、较高的能量密度以及快速充放电能力，成为产业重点的发展趋势。近年来，产业通过CVD法制备新型硅碳在纳米结构调控、碳包覆优化、粘结剂体系改进及制备工艺升级方面取得突破性进展，随着成本下降及产业链协同发展，硅碳负极正迈向规模化量产阶段。

An e-bike, also known as a booster bicycle, consists of an integrated electric motor for propulsion. Based on the power that the electric motor can deliver and control the system, e-bikes can be classified as e-bikes with pedal assist only, those with power-on-demand and pedal assist, and those with power-on-demand only. An e￾bike battery is used to power e-bikes and is basically a rechargeable battery, which can be recharged at any charging station or at home.

Batteries are one of the most important components of electric vehicles (EVs). EVs require batteries for both propulsion and starting lighting, and ignition (SLI). Batteries play a major role in the adoption of EVs due to their importance in determining the driving range, the cost of ownership, and the performance of the EVs.

An Electric Vehicle (EV) charging station is a facility or piece of equipment that provides electrical power to recharge the batteries of EVs. These stations are basically of two types, AC charging stations and DC charging stations.

Electricity trading enhances grid stability, encourages competition, reduces prices, and makes renewable energy integration easier in global energy markets. Electricity trading refers to the buying and selling of electricity among participants in the electricity industry, such as independent power producers, open-access consumers, and municipality-owned utilities. Various forms of electricity trading are possible depending on market design, ranging from short-term trading to long-term trading. Electricity can be traded on exchanges, over the counter (OTC) with an intermediary, and directly OTC with no intermediary.

A fired heater is used for heat generation by combustion of oil or gas or a mixture of them. The fluid that is flowing in the heater is heated without changing state or with vaporization already started at the fuel inlet. Fired heaters are used for steam generation and petroleum refining in refineries; gas plants; chemical and petrochemical industries; and olefins, ammonia, and fertilizer plants.
