Introduction

With the rising demand for vehicle safety and intelligent monitoring, Tire Pressure Monitoring Systems (TPMS) have become an essential feature in modern cars and fleets. However, powering these sensors under harsh automotive conditions requires highly reliable, long-life batteries. Semi-solid lithium batteries combine high energy density, thermal stability, and extended cycle life, making them ideal for TPMS applications.

As a professional lithium battery manufacturer, PKNERGY delivers custom semi-solid lithium battery solutions tailored for automotive OEMs and Tier-1 suppliers worldwide.

Application Background

TPMS sensors are embedded in wheels to monitor tire pressure, temperature, and condition in real time. They require:

Compact, lightweight battery cells
Long cycle life (5–10 years)
Wide operating temperature range (-40°C ~ +125°C)
Resistance to vibration, humidity, and corrosion
Cost-effective, stable performance

Traditional Li-ion or coin-cell batteries struggle in such extreme environments. Semi-solid lithium batteries overcome these issues by combining liquid-like conductivity with solid-state safety.
