Flexible Battery Design: Bridging Lab Prototypes to Market Viability

CCS Chemistry · 2023

Key Findings

01Current flexible battery (FB) prototypes often fall short of market-required energy density, flexibility, and safety benchmarks.
02Specific cell configurations and material choices are critical for achieving both high flexibility and energy density.
03Robust safety enhancement strategies are necessary for widespread adoption.

Application

Design takeaway

How to apply

When specifying batteries for a new flexible electronic device, benchmark the chosen battery's energy density, cycle life, and safety features against the performance of leading-edge flexible battery research and industry standards.

Project actions

01When researching battery options for a flexible product, look for data that compares performance metrics like energy density (Wh/kg or Wh/L) and flexibility (e.g., bend radius) against industry benchmarks.
02Consider the safety features of different battery chemistries and designs, especially for wearable applications.

Method & Evidence

AimWhat are the key performance metrics (energy density, flexibility, safety) that must be optimized to transition flexible batteries from laboratory prototypes to commercially viable products?

MethodComparative analysis and literature review

ProcedureThe research systematically compares the performance figures of merit (FOM) of existing lithium-based and zinc-based flexible batteries with the requirements for market applications. It analyzes optimal cell configurations for flexibility, discusses material selection for high energy density, and explores strategies for enhancing battery safety, concluding with an outlook on future development needs.

Strengths & Limitations

Strengths

+Comprehensive analysis of critical performance metrics.
+Focus on bridging the gap between research and market application.

Limitations

The availability of reliable, comparable data for all flexible battery technologies can be challenging. Safety testing can be complex and requires specialized equipment.

Reliability & validity

The validity of the findings relies on the accuracy and comparability of data reported in the reviewed literature. Reliability is enhanced by the systematic comparison of multiple FB types against defined metrics.

Think critically

Given the trade-offs between energy density, flexibility, and safety, how might a designer prioritize these factors for different types of flexible electronic products (e.g., a smartwatch versus a medical patch)?

Design Principles

"Market-driven performance optimization for emerging power technologies."

For designers and engineers developing wearable electronics or other flexible devices, understanding the critical performance benchmarks for flexible power sources is essential. This insight highlights the gap between current capabilities and market readiness, guiding development efforts towards practical, scalable solutions.

What This Means for Your Design

To make bendy batteries that people can actually buy, they need to store more power, be super bendy, and be totally safe, not just work in a lab.

How to use in your project
