碳酸锂资金预期反复引发高位宽幅区间震荡
Tong Hui Qi Huo· 2025-08-22 08:35
需求端:新能源汽车零售同比增9%,但当前终端需求仍处淡季,车厂备货 谨慎;三元材料价格受镍钴成本推动上行,叠加厂商提锂系数挂钩结算 价,支撑碳酸锂刚需采购。磷酸铁锂电芯价格微跌0.2%,成本传导尚未完 全兑现,动力电池企业备货力度有限。 库存与仓单:碳酸锂总库存环比小幅下降0.1%至14.23万吨,去库速度仍 慢。 市场小结 碳酸锂资金预期反复引发高位宽幅区间震荡 一、日度市场总结 碳酸锂期货市场数据变动分析 主力合约与基差:8月21日碳酸锂主力合约收报82760元/吨,较前一日上涨 2.2%,呈现企稳反弹迹。基差大幅走弱至540元/吨,现货跟涨乏力,市场 对远期价格预期转弱。 持仓与成交:持仓量小幅收缩1.3%至39.0万手,成交量环比下降7.3%,市 场情绪趋向谨慎,部分资金高位止盈离场。 产业链供需及库存变化分析 供给端:锂辉石/云母精矿价格维持稳定,宁德时代宜春云母矿因采矿证到 期停产可能引发区域供应扰动。当前碳酸锂产能利用率维持63.9%的平稳水 平,但原料端因成本倒挂出现惜售,可能抑制未来锂盐生产积极性。 短期碳酸锂期货或转入宽幅震荡格局。上行阻力主要来自现货市场跟涨不 足及高库存压力,而下方支撑 ...

Core Viewpoint - The new national standard for electric vehicle batteries in China aims to enhance safety by implementing stricter requirements, particularly regarding fire and explosion prevention, while acknowledging that no technology can completely eliminate the risk of battery fires [1][2][11]. Group 1: New National Standards - The new standard, GB38031-2025, modifies previous requirements by mandating that batteries must not catch fire or explode, and that smoke must not harm passengers [1][2]. - New testing methods have been introduced, including internal heating tests to simulate harsher conditions, in addition to existing external heating and puncture tests [2][8]. - The new standards also include bottom impact tests and safety tests after fast charging cycles, which battery manufacturers must meet [8][10]. Group 2: Battery Safety and Technology - Achieving safety at the pack level (NTP) is not sufficient; extreme conditions cannot be fully covered by current testing methods, indicating that driver behavior remains crucial for safety [3][4]. - The intrinsic safety of individual battery cells is significant for the overall safety of the battery pack, with safer cell designs contributing to compliance with national safety standards [5][11]. - Material choices, such as using polyimide (PI) for separators instead of polypropylene (PP) or polyethylene (PE), could enhance safety, although cost and commercial viability are challenges [7][12]. Group 3: Industry Implications - The new standards may lead to a reshuffling among battery material suppliers, but many manufacturers already adhere to high standards, minimizing upstream impacts [12]. - The enforcement of the new standards may require stronger penalties to deter potential shortcuts in manufacturing processes, as merely raising standards may not eliminate all risks [13].
