1. Introduction

In the fast-paced world of professional communication, two-way radios are critical tools for industries from security and logistics to construction and event management. Reliable battery performance directly affects efficiency and safety.

Traditional lithium-ion batteries face limitations such as thermal instability and shorter lifespan under harsh conditions. Semi-solid lithium-ion batteries have emerged as a next-generation solution, offering higher energy density, improved safety, and extended cycle life.

2. Application Background

Two-way radios require batteries that can withstand frequent charge/discharge cycles and maintain stable power in variable temperatures. Key challenges include:

• Compact Size: Lightweight batteries that fit portable designs.
• High Discharge Rate: Support high-power bursts for transmission.
• Extended Lifespan: Maintain capacity over hundreds of cycles.
• Safety & Reliability: Operate safely in extreme environments.

Semi-solid lithium-ion technology combines the advantages of solid-state and liquid electrolytes, providing a balanced solution for custom battery packs used in modern communication equipment.
