Ensurge solid-state lithium microbatteries enable form factor freedom. It allows OEMs to shape the microbattery to their product to meet market needs instead of the other way around.

Battery solutions from Ensurge Micropower have at least twice the Volumetric Energy Density (VED) of Li-ion batteries which means they can have very high battery capacities (mAh) in a much smaller volume/size.

Products implemented with Ensurge's solid-state battery solutions will let end-users to quickly charge them. They can recharge these wearables and IoT devices at 90% capacity in less than 25 minutes.

For OEMs, they can reduce design time since Ensurge microbatteries utilize a simple and low-cost charging circuit thus realizing BoM and PCB area savings.

Ensurge microbatteries can handle very high current pulses from current and next generation low power RF SoCs in wearable and IoT applications. These solid-state lithium microbatteries can support up to 10C discharge pulses vs. 2C in Li-ion batteries.

OEMs implementing Ensurge battery solutions can realize efficient and cost-effective manufacturing process since SMT assembly equipment and reflow oven may be used. Unlike Li-ion batteries, manual assembly or soldering is not required and OEMs can achieve lower assembly costs and higher production throughput.

Battery solutions from Ensurge are safe in carry-on or checked-in baggage as it will not catch fire or explode since it has a solid electrolyte unlike liquid-based electrolyte Li-ion batteries. Therefore, Ensurge microbatteries are compliant to UN38.3, UL 1642 and IEC 62133-2 standards. Secondly, no battery protection circuitry is necessary to protect it from over-current or over-voltage conditions while this is a must for Li-ion batteries.

Ensurge's solid-state lithium batteries and the products that use them can be stored on the shelf or warehouse for 6 months or more and still maintain it's level of charge whereas Li-ion batteries will lose all of its charge. Also, they will not corrode during that time.

Ensurge's solid-state lithium microbatteries maintain their capacity (>80%) throughout their lifetime since they can support more than 1,000 discharge/charge cycles. Also, there is no or minimal memory effect on the microbattery's capacity.

Li-ion batteries have a narrow operating range, but this is not so for Ensurge's solid-state lithium microbatteries that can be operated and stored over a wide temperature range. This feature lets OEMs design end-products to be used in extreme environments.
