Core Viewpoint - The potential renaming of "semi-solid battery" to "solid-liquid battery" has sparked significant interest in the industry, highlighting long-standing concerns about terminology confusion and its implications for market clarity and development [2][3]. Industry Terminology and Clarity - The term "semi-solid battery" has been criticized for being vague and easily confused with "solid-state battery," leading to misconceptions among consumers and manufacturers [3]. - The proposed term "solid-liquid battery" more accurately describes the technology, as it retains some liquid electrolyte while incorporating solid electrolyte materials to enhance performance [3]. - Industry experts emphasize the need for clearer terminology to facilitate communication, collaboration, and standardization within the battery sector [5]. Technological Advancements - Solid-liquid batteries theoretically offer improved energy density and charging speed compared to traditional lithium batteries, although they still carry some risks associated with liquid components [3][9]. - In contrast, solid-state batteries utilize entirely solid electrolytes, providing higher energy density, faster charging, and enhanced safety due to the absence of liquid components [4]. Industry Development and Collaboration - The renaming initiative aims to standardize battery classifications, which could foster better communication and cooperation among industry players, including material suppliers, battery manufacturers, and automotive producers [5][6]. - Enhanced clarity in terminology is expected to lead to more precise alignment of development goals across the supply chain, promoting collaborative research and production efforts [6][7]. Market Implications - Solid-liquid batteries are anticipated to play a crucial transitional role in the battery market until solid-state technology matures, addressing consumer demands for higher energy density, faster charging, and improved safety [9]. - The introduction of solid-liquid batteries is expected to alleviate consumer concerns regarding range anxiety in electric vehicles by extending driving range and reducing charging times [9]. Future Prospects - The technological advancements and industry experience gained from solid-liquid batteries are likely to benefit the future development of solid-state batteries, facilitating faster industrialization and scaling of production [10].

面对北方冬季的严寒，电动汽车的动力电池基本都会呈现不同程度的衰减，这也成为行业和消费者的"痛点"之一。而近来，发展"全天 候动力电池"已经从理论正在走近现实，为解决诸如此类的问题带来了"良方"。 打通堵点突破困境 很多电动汽车用户都有同样的感受，低温衰减，是纯电动汽车的"冬季魔咒"。 每至寒冬，北方的电动汽车车主便会或多或少陷入焦虑。在低温环境下，传统锂电池性能会打折扣，这几乎成了新能源车绕不过去的一大"痛 点"。如果在东北地区摄氏-20℃以下的极寒环境中，会影响到传统锂电池使其容量保持率常常不足70%，这意味着，原本满电状态下能行驶500公里 的纯电动汽车，在这样的低温下，实际续航里程可能锐减至350公里以下。而且，如果是在高速公路上行驶，速度越快，电量消耗得也越快。据一 些车主反映，与此同时，寒冷冬季车载空调的使用也进一步加剧了能耗矛盾。在寒冷的冬天，不开空调难以忍受，但打开空调后，电量的消耗速度 急剧加快，加剧了"电池焦虑"，影响了用户体验。 面对传统动力电池在极端气候下的困境，"全天候动力电池"概念应运而生。从科研界到相关企业都在积极探索，从技术底层寻求突破，使动力 电池能全天候运行，为新能源汽车突破 ...
