Semi-Solid Lithium-ion Battery

What makes a semi-solid battery different?

One change: gel instead of liquid. Swapping out the liquid electrolyte found in conventional lithium-ion batteries makes the cell dramatically harder to ignite, extends its life to around 2,000 charge cycles, and lets it run from −15°C to 45°C. All in a body no bigger than the power bank you're carrying today.

High safety

Conventional lithium-ion batteries carry a liquid electrolyte. ELECOM's semi-solid power bank uses a gel and that one change makes all the difference. Fewer flammable vapours. Far less gas released under stress. A dramatically lower risk of fire. We didn't stop at the electrolyte either: every material and process inside the cell is chosen with safety in mind.

Wide temperature range

Wide temperature range Conventional mobile batteries typically have a discharge temperature range of 0°C to 40°C. This product can withstand a wide temperature range of -15°C to 45°C, so you can use it with peace of mind even in extremely hot or cold climates.
_{* Depending on the connected devices and the conditions of this product, the output may decrease or stop altogether.

This is the operating temperature range during discharge.}

Thermal Protection

Monitoring the temperature while power is on and protect your equipment.

Reliable Circuit Design

With multiple layers of protection, the system automatically stops operation when an anomaly is detected, preventing accidents.

Low current mode

Charges small electronic devices with low charging currents, such as earphones, with the optimal current.

LED Display

See at a glance when it's time to charge, you can use it with peace of mind without worrying about the remaining battery level.

Compact

Compared to lithium iron phosphate batteries and sodium ion batteries, which are safer than conventional lithium-ion batteries, this battery has a smaller volume and achieves portability comparable to conventional mobile batteries.

PPS Compatible

By adjusting the voltage in 0.02V increments, it can efficiently supply the optimal power, enabling efficient, safe, and high-speed charging of PPS-compatible devices (such as Galaxy and Pixel).

Painted Finish

This painted finish resists fingerprints and dirt, maintaining a clean appearance for a long time. It makes it easy to keep things hygienic.

Flight Safe

This product is under 100Wh, so it can be carried on board an airplane.
