技術簡介

鉛酸電池具備成本低廉、技術成熟、放電能力強，且能承受較高瞬間電流等優勢，至今在儲能與備援電源市場中仍佔有不可取代的地位。矽焦耳（Silicon Joule）電池透過以矽晶片取代傳統鉛格柵，形成關鍵的電雙極結構，在維持鉛酸電池高安全性與高回收率的前提下，此技術可顯著提升功率密度、充放電效率及循環壽命，同時降低鉛用量，具備高度產業化潛力。電雙極板為矽焦耳電池之核心元件，其主要功能為承載正負極活性物質，提供低內阻且均勻的電流通道，進而提升能量與功率密度、減輕整體重量並強化結構安全性。

Abstract

The main advantages of lead-acid batteries include low cost, mature technology, strong discharge capability, and the ability to withstand high instantaneous currents. As a result, they continue to hold an irreplaceable position in the energy storage and backup power markets. Silicon Joule batteries utilize silicon wafers to replace conventional lead grids, forming a critical bipolar structure. While maintaining the high safety and recyclability of traditional lead-acid batteries, this technology significantly improves power density, charge-discharge efficiency, and cycle life, while reducing lead consumption, demonstrating strong potential for industrialization. The bipolar plate is the core component of a Silicon Joule battery. Its primary functions are to support the positive and negative active materials, provide a low-resistance and uniform current conduction pathway, enhance energy and power density, reduce weight, and improve structural safety.
