What Does Ensurge Do?
We unlock product innovation and performance with the first microbattery to meet the special needs of hearables, wearables and IoT connected devices.
Ensurge unlocks product innovation and performance for hearables, wearables and IoT sensors with the first solid-state microbattery to meet their special requirements including high energy density, fast charging and customizable form factors. All made possible through patented process technology, materials advances and scalable Roll-to-Roll manufacturing at Ensurge's Silicon Valley facility.
Why is Li-ion Falling Short?
Limited Energy DensityLi-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 RestrictionsEnd-product form factors have been restricted to what is possible using the standard Li-ion battery sizes and cylindrical shapes.
Manual Assembly RequirementsLi-ion batteries do not support standard automated PCB assembly processes and require a fixed-size coin cell socket.
Slow Charging TimesLi-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 CapabilityTo 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.
SafetyLi-ion batteries must sacrifice energy density and form-factor freedom for safety mechanisms to protect their vulnerable liquid electrolyte.

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.Learn More for Ensurge Microbattery Fills a Gap
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.Learn More for Ensurge Solid-State Lithium Battery Technology
