日产全固态电池续航翻倍,争取2028年度量产

Core Viewpoint - Nissan aims to revolutionize the electric vehicle (EV) market with its next-generation all-solid-state batteries, achieving double the range of current batteries and targeting a cost of $75 per kilowatt-hour, which could significantly lower the average global battery pack price by 30% by 2024 [2][7]. Group 1: Battery Technology - The all-solid-state battery, composed of numerous "cells," has achieved performance metrics that meet practical application goals, with energy density increased to double that of existing lithium batteries, allowing for doubled EV range with the same battery size [4]. - All-solid-state batteries can withstand high-power charging, reducing charging time to one-third compared to traditional batteries [4]. - The solid electrolyte used in all-solid-state batteries prevents unexpected side reactions and can operate at high temperatures, enhancing battery performance [5]. Group 2: Manufacturing and Collaboration - Nissan has partnered with the American startup LiCAP Technologies to utilize their electrode manufacturing technology, which incorporates a fibrous binder in the positive electrode material, enhancing ion mobility and efficiency [6]. - The "dry electrode" manufacturing method used by LiCAP Technologies eliminates the need for drying compounds during production, making cost control easier, although large-scale production capabilities are still a challenge [6]. - Nissan has initiated a pilot production line to master mass production technology, focusing on producing complete batteries rather than just cells [7]. Group 3: Competitive Landscape - Toyota plans to start mass production of all-solid-state batteries in the fiscal year 2027, indicating a competitive race among Japanese automakers, who currently lead in this technology [7]. - The all-solid-state battery is viewed as a key technology for Japanese automakers to regain market share in the battery sector, where they currently hold about 70% in China [7].
