Solving the Microbattery Industry’s Toughest Technological Challenges
Ensurge has applied an ultrathin 10 µm stainless steel substrate, innovative core-cell stacking and packaging, Roll-to-Roll processing and materials innovations to a proven and established solid-state chemistry to achieve the powerful, durable, and reliable Ensurge Microbattery.
Innovative Microbattery Architecture
Ultra-thin 10 µm Stainless Steel Substrate
The Ensurge Microbattery's 10 µm stainless steel substrate is a significant contributor to Volumetric Energy Density (VED) that is orders of magnitude better than competitive alternatives that use much thicker ceramic and silicon substrates. Stainless steel offers additional benefits as it is a natural conductor and moisture barrier and offers high mechanical strength, further enhancing the Ensurge Microbattery's performance and reliability.
Roll-to-Roll Manufacturing Facility
The Ensurge Microbattery is manufactured at Ensurge's own state-of-the-art Roll-to-Roll production facility located in Silicon Valley. Roll-to-Roll processing is more efficient and scalable, and inherently leads to higher throughput and lower cost within a conventional manufacturing environment that does not need stringent humidity and air controls.
Established Anode-less Solid-State Chemistry
The Ensurge Microbattery is based on an established and proven anode-less solid-state lithium chemistry accelerating Ensurge's engineering development. The anode-less architecture allows Ensurge to use a much simpler manufacturing environment. Ensurge has innovated within this chemistry with new materials and packaging that deliver high Volumetric Energy Density (VED), fast charging and high-pulse discharge.
Innovative Cell-stacking & Packaging
Precise and efficient semiconductor tools and processes are used to create ultra-compact stacked and packaged Ensurge Microbatteries. This approach maximizes the Volumetric Energy Density (VED) of the Ensurge Microbattery while ensuring high performance, customizable form factors and the ability to provision contacts for direct PCB connection.
Ensurge Solid-state Lithium Battery Technology
Ensurge Solid-State Lithium Technology vs. Lithium Ion (Li-ion)
The biggest difference between the batteries is that Ensurge's technology uses a solid electrolyte vs. a liquid one in Lithium ion (Li-ion).
Ensurge solid-state technology also charges three times faster, has more than twice the cycle life, supports multiple times pulse current and supports flexible form factors.
Ensurge Solid-State Lithium Technology vs. Lithium Polymer (Li-poly)
Lithium Polymer (Li-poly) technology is similar to Li-ion except it uses a gel-like material for the electrolyte vs. liquid electrolyte used by Li-ion. Ensurge solid-state lithium technology provides for 4x or more energy density advantage vs. Li-poly especially high in small form factor, 1 mAh to 100 mAh capacities. Other advantages include faster charging, high pulse current and higher cycle life.
Ensurge vs. Other Solid-State Chemistry
One key difference is the use of 10 µm stainless steel substrate vs. ceramic and silica used by the competitors that are 100's of microns thick. As a result, their energy density is orders of magnitude lower and they are only able to provide batteries with few hundred µAh capacity that has very limited target applications. Ensurge solid-state lithium technology with much higher energy density is able to deliver 1 mAh to 100 mAh capacities that will enable wearables, hearables and IoT connected devices to really take off.
