Why is li-ion falling short ensurge

Why is Li-ion Falling Short?

  • Limited Energy Density
    Li-ion batteries have a lower energy density and protective interior packaging that limits their capacity. In addition to VED limitations, Li-ion microbatteries also fall short in charge cycles and shelf life.
  • Form Factor Restrictions
    End-product form factors have been restricted to what is possible using the standard Li-ion battery sizes and cylindrical shapes.
  • Manual Assembly Requirements
    Li-ion batteries do not support standard automated PCB assembly processes and require a fixed-size coin cell socket.
  • Slow Charging Times
    Li-ion batteries have much slower charging times, which frustrates end-users who need their devices to be quickly re-charged for continued operation. Also, this limitation is exacerbated by the specific charging protocol Li-ion batteries must follow to be properly charged.
  • Low Current Pulse Discharge Capability
    To support new wireless protocols for wearable, hearable, fitness/sports and IoT devices, Li-ion batteries must be sized to handle the highest current pulse discharge. This results in a much larger battery than may be needed for the end-product, which also consumes valuable space.
  • Safety
    Li-ion batteries must sacrifice energy density and form-factor freedom for safety mechanisms to protect their vulnerable liquid electrolyte.

How Ensurge Microbattery Solves the Problem

  • Better Performance

    Better Performance

    2x Li-ion's energy density and charging speed, up to 3x the recharge cycles and 5x the charge retention when idle or in storage.
  • Form Factor Freedom

    Form Factor Freedom

    Customizable sizes and shapes unlock innovation for smaller and more comfortable wearable, hearable and IoT sensor designs.
  • Simplified End-Product Integration

    Simplified End-Product Integration

    Can be assembled into an end-product using the same automated SMT processes as other electronic components.
  • Superior Safety and Reliability

    Superior Safety and Reliability

    Hearables, wearables and IoT sensors can now be powered by a safer microbattery than Li-ion batteries, with a longer shelf life.
  • Innovation

    Innovation

    Enables OEMs to add features and functions to their products that were not possible with Li-ion batteries.

What's New

Ensurge Microbattery Fills a Gap

Ensurge Microbattery Fills a Gap

Ensurge's innovative solid-state lithium microbattery fills the industry gap for rechargeable 1 milliampere-hour (mAh) to 100 (mAh) products with the energy density, customizable form factors, charging speed and high-volume manufacturability to power a new generation of wearable and connected devices.

Ensurge Solid-State Lithium Battery Technology

Ensurge Solid-State Lithium Battery Technology

Ensurge's anode-less rechargeable solid-state lithium battery technology breaks the Li-ion barrier that has limited product innovation. It enables safer, better-performing and more reliable microbatteries that are easier to assemble into ultra-small connected devices. And it removes Li-ion's size and shape constraints so the products they power can be smaller, thinner and more comfortable and effective.
