Our Solutions for Children's Audio Player Device Lithium Battery Challenges

Lithium batteries for traditional children's audio players have safety risks like liquid leakage and swelling, which can’t meet the strict safety standards for children's products; large voltage difference easily leads to unstable device operation, and high self-discharge rate results in short battery life, making them unsuitable for long-term use; insufficient energy density makes it hard to balance capacity and weight, affecting how comfortably children hold the device.

Lithium Polymer Battery for children audio player

Safety Protection Upgrade:

Use high-strength polymer shells and sealing materials, together with vacuum sealing technology; introduce online inspection systems, optimize positive pressure leak detection processes, and conduct positive pressure testing before delivery to avoid safety risks.

Battery Life and Voltage Stability:

Precisely design the battery structure; each battery has an exclusive QR code linked to K-value data for traceability and sharing; select and match batteries through 4 rounds of OCV equipment testing, controlling voltage difference within 5mV-10mV and reducing self-discharge rate.

Lightweight Adaptation:

Adopt high-energy-density battery cells to reduce weight by 15%-20% with the same capacity; provide flexible size customization to fit the internal structure of the product.
