报废的汽车去哪儿了 可用零部件标注“出身”后进入售后市场
Chang Jiang Ri Bao· 2025-07-08 01:04
汽车开到一定年限,一部分车会进入二手车市场,另一部分车则会进入报废流程。这些报废 的车去了哪儿? 近日,长江日报记者前往位于蔡甸区的武汉东风鸿泰汽车资源循环利用有限公司(以下简称 东风鸿泰)进行探访。 上午10时,一辆超过15年车龄的东风日产SUV被拖进东风鸿泰报废车拆解区,随着两名拆解 工手中的工具轰鸣,这辆车的轮胎、车灯、保险杠、发动机、变速箱等被一一拆卸下来。下午2时 许,经过四小时的拆解,这辆SUV只剩下一个空壳。 这辆车车况较好,车门、保险杠、车灯、散热器、冷凝器等零部件经检测后,功能正常。工 作人员王和安说:"'五大总成'以外可以直接回用的零部件,我们会在显眼处用激光设备刻印上'汽 车零部件再制造产品标志'和可追溯的条码,一扫便知零部件的来源信息。" 东风鸿泰拆解区工作人员正在拆解车辆。 报废车拆下来的可用零部件进入售后市场前,要刻印"汽车零部件再制造产品标志"。 个人车主如要选择车辆报废,可先前往交管部门提交报废申请,经审核通过后,将车辆交给 有资质的公司进行报废处理。 王和安举例,一辆车龄较老的汽车出现变速箱损坏,且不适合再维修。车主出于成本,可能 考虑更换一台经过再制造的变速箱。"相较全新的 ...

荣耀新机发布,搭载固态电池!
DT新材料· 2025-07-07 15:57
【DT新材料】 获悉,近日 , 荣耀 发布了新款折叠屏手机Magic V5,该手机搭载了青海湖刀片电池,容量6100mAh。 据悉,该电池最大特点是"薄",单个电芯厚度0.18mm,且电池含硅量极高,达25%,能量密度为901Wh/L, 采用三大固态电 池技术:自修复材料、叠片电芯和固态电解质。 该电池最早亮相于2023年,当年3月随荣耀Magic 5出现,成为业界首个量产的硅碳负极电池技术的品牌,第二年2月同样搭载 于荣耀Magic 6相关机型,并拓展至Magic6至臻版、RSR保时捷设计版等机型。 第一代青海湖电池硅含量5%,到了第二代就上升至10%,第三代青海湖刀片电池直接将含量升至25%, 硅材料比传统的石墨 材料"更有劲儿",储电能力是石墨的11倍以上。 硅基负极 虽然是前景远大的材料,但硅材料有一个极大的弱点,成为业界长时间的困扰,那就是膨胀问题,在充电时,硅颗 粒体积膨胀可达到三倍大,其体积变化与海绵无异,如此不稳定的物理形态让许多研发部门感到犯愁。 为此,荣耀研发部门寻找到了破解技术,那就是 在分子层面编织防护网,让纳米级的硅颗粒包裹于碳基骨架,形成弹性复合 结构 ,该结构的电能存储性也相当好 ...
这款“逆天”电池充满电仅需18秒!已经量产装车!背后藏着什么黑科技?
电动车公社· 2025-07-07 15:53
关注 「电动车公社」 和我们一起重新思考汽车 今年 3 月份,比亚迪发布"兆瓦闪充"时, 最高1000kW的充电功率、5分钟补能400km, 不知刷新了多少人的认知。 但你敢相信吗?这块充电倍率10C的电池,远没到充电速度的极限。 就在前段时间,英国公司 RML 集团研发了一款名为 VarEVolt 的电池系统。其最高充电倍率,竟然高达200C! 这也就意味着, 理论上从 0 充满,只需 18 秒的时间! 如此恐怖的充电速度,对目前市面上所有在售的电动车产品,绝对称得上降维打击。 不仅如此,官方还宣称这款电池的 功率密度达到了 6kW/kg, 同样是个非常逆天的数字。 相比之下,常见的三元锂电池功率密度一般在 1-2kW/kg(一块500kg的电池包放电功率能达到1000kW就很不错了) ,而 VarEVolt 电池 是它的 3 倍还 多! 可以说, VarEVolt 电池 无论充电速度还是放电能力,都做到了目前市面上量产电动车无法匹敌的程度,甚至都有点 "物理学不存在" 了的味道。 更离谱的是,在不久之前 VarEVolt 电池 获得了英国 UN ECE Regulation 100 认证, 具备量产资格。 ...

可转债周报:潜心埋伏,静待双击机会-20250707

Report Industry Investment Rating No relevant content provided. Core View of the Report - Appropriate realization and waiting for layout opportunities. Currently, the convertible bond market is facing supply - demand contradictions and high valuations. In the context of potential increased volatility in the equity market, convertible bonds may face valuation adjustment pressure. Short - term investment should focus on large - cap debt - biased varieties, avoid bonds with overly high downward - revision expectations, realize profits appropriately, maintain a flexible position, and wait for the next layout opportunity [2][45]. Summary According to the Directory 1. Appropriate Realization, Waiting for Layout Opportunities - **Market Performance in Q2**: The equity market showed a deep "V" trend in Q2. The convertible bond index rose 3.4%, outperforming the Shanghai Composite Index. The low - price index rose 2.7%, and the equal - weighted index rose over 4% [12]. - **Supply - demand Analysis**: In Q2, convertible bond supply accelerated, with 11 new issues and a scale of 8 billion yuan. However, due to maturities and forced redemptions, the total scale decreased by over 55 billion yuan compared to Q1. The short - term supply supplement is limited. On the demand side, it first decreased and then increased. In June, there was a large - scale capital inflow [13][21]. - **Valuation Analysis**: The valuation of balanced convertible bonds rose significantly at the end of June, breaking through the annual high. The valuation of debt - biased convertible bonds reached a historical high, while the valuation of equity - biased convertible bonds remained at a low level [39][40]. 2. Market Review 2.1 Equity Market: Index Continued to Rise Strongly - **Index Performance**: Last week, the Shanghai Composite Index and the ChiNext Index rose 1.4% and 1.5% respectively. The market trading volume rebounded, and the theme hotspots rotated actively [47]. - **Style and Sector Performance**: Industries such as steel and building materials led the rise, while the banking sector reached a new high for the year. Some sectors such as computer and non - bank finance declined [47]. - **Valuation**: The PE (TTM) of all A - shares was 15.76X, and the PE (TTM) of the ChiNext was 36.38X, both showing an upward trend [48]. 2.2 Convertible Bond Market: Valuation Continued to Rise - **Index and Trading Volume**: The CSI Convertible Bond Index closed at 447.46, rising 1.21%. The average daily trading volume was 64.766 billion yuan, a 11.85% increase from the previous period [54]. - **Individual Bond Performance**: Dianhua, Saili, and Anke led the gains, while Jinji, Sanyang, and Jingduan led the losses [54]. - **Valuation**: The conversion premium rate of convertible bonds with a parity of 90 - 110 was 26.42%, and the average YTM of convertible bonds with a parity below 80 was - 0.27%, indicating a significant increase in valuation [56]. 3. Convertible Bond Investment Strategy 3.1 Stock Market - In the short term, the external uncertainty has increased significantly, and the index volatility may intensify. The broad - based index will be in a volatile state, and investors can focus on sectors such as innovative drugs, self - controllability, AI +, and solid - state batteries, as well as industries with improved prosperity [3]. 3.2 Convertible Bonds - The overall view is neutral and cautious, preferring structural individual bond opportunities. Specific areas to focus on include TMT, robotics, low - altitude areas, innovative drugs, debt - resolution directions, price - rising cyclical sectors, bottom - position bonds, and newly - listed bonds [4]. 3.3 Primary Market Tracking - Last week, 2 new convertible bonds were issued, 1 convertible bond was approved by the shareholders' meeting, and 1 convertible bond issuance was accepted by the exchange [5][68].
