哪类充电宝最危险?
Hu Xiu· 2025-07-01 00:53
近期,多个品牌充电宝厂家因电芯存在安全风险实施召回,而此前国家市场监督管理总局已撤销或暂停了多个充电宝及电芯厂家3C认证。6月 26日,民航局发布紧急通知,自6月28日起禁止旅客携带没有3C标识、3C标识不清晰、被召回型号或批次的充电宝乘坐境内航班,以保障航空 运行安全。3C认证,即"中国强制性产品认证"(China Compulsory Certification),是我国依法实施的强制性市场准入制度。 一时间,充电宝安全性又成为公众关注的问题。你手上的充电宝是否带有3C认证?或许并不为所有人知的是,充电宝所携带的能量很少,但 若事故发生,产生的威力却很大! 本文来自微信公众号:返朴 (ID:fanpu2019),作者:李存璞(重庆大学化学化工学院教授,中国化学会科普工作委员会委员),原文标 题:《这类充电宝最危险,家家可能都有!》,头图来自:AI生成 随着罗马仕充电宝召回事件的发酵,机场出发层被暂扣的充电宝可能已经比打火机还要多。一时间,充电宝仿佛变成了"小型燃烧弹",回家检 查自己充电宝是否具有3C认证,或者干脆想办法购买3C认证贴纸(这是违法行为!),成了不少读者看到这一新闻的第一反应。 可是,我们明 ...

磷酸铁锂的反攻
远川研究所· 2025-06-09 13:04
以下文章来源于远川科技评论 ,作者徐珊珊 远川科技评论 . 刻画这个时代(的前沿科技) 失意者通常有两种结局,要么一蹶不振,要么绝地求生,磷酸铁锂电池属于后者。 2021年6月,磷酸铁锂电池装机量反超三元锂电池,成为动力电池市场的主流选择。此后开启神挡杀神的开挂人生, 份额一路提高到72%,重回十年前的巅峰水平。 今年1-4月,国内磷酸铁锂电池装机份额超过80%,可谓独孤求败。向来以技术先进性自我标榜的海外车企,也罕见地 为磷酸铁锂摇旗呐喊。 磷酸铁锂和三元锂的技术讨论几乎与新能源车的历史一样长,这个问题在当下似乎又有了新的解读。 过去十年的动力电池市场可以清晰的划分为两个阶段,也是磷酸铁锂电池从波峰到谷底、再卷土重来的过程。 到"十城千辆"计划结束,25个示范城市共售出27432辆新能源车,其中个人采购量只有4400辆[1]。虽说成绩单不算理 想,但最大成果是培育了以"锂电四大天王"比克、比亚迪、力神和ATL(后孵化出宁德时代)为代表的电池生产商。 危险的地位 磷酸铁锂和三元锂的缠斗,可以一路追溯到2009年的"十城千辆"计划。 时值新能源产业链蹒跚起步,迎来为期三年的培育期,补贴力度可以用送钱形容:10米 ...

拟投资9亿美元,力拓与智利国家铜业将合作开发锂矿
Xin Lang Cai Jing· 2025-05-20 03:22
力拓集团是全球最大的矿业公司之一,在铁矿石、铝、铜等资源方面占据了重要的市场份额。近年来, 力拓开始布局锂矿业务。 2021年,力拓宣布以8.25亿美元收购阿根廷Rincon矿业公司项目,2022年3月完成了此次收购。去年12 月,力拓批准出资25亿美元扩建阿根廷的Rincon项目,预计到2028年项目年产量从3000吨提高到6万 吨。 今年3月,力拓集团完成以67亿美元收购阿卡迪姆锂业股份有限公司(Arcadium Lithium)的交易,正式跻 身为全球第三大锂生产商。合并后的力拓锂业板块整合了阿根廷盐湖提锂项目、西澳Mount Cattlin硬岩 锂矿,以及分布在中美日的氢氧化锂产能。公司计划到2028年实现年产20万吨碳酸锂当量。 近两年,碳酸锂价格持续走跌。业内人士表示,受供求关系影响,目前碳酸锂价格仍在筑底。预计2026 年,在高价产能出清之后,供需边际将持续改善;加上需求结构升级、人形机器人等新领域对高能量密 度电池的需求,或将带动碳酸锂价格修复。 矿业巨头力拓5月19日宣布,该公司与智利国家铜业公司将组建合资企业,开发和运营智利马里昆加盐 湖锂项目。该交易预计明年一季度末完成。 根据协议,力拓 ...
