L Shaped Battery

In addition we own advanced level technologies in battery production

L Shaped Battery

L Shaped battery

Gun-type L Shaped battery

V-Shaped battery

To pursue higher capacity, we aimed to maximize the utilization of the irregular space inside the fuselage, and insert larger-capacity batteries. It is a trends that many consumer electronic products are switching to shaped batteries, such as smart phones and VR/AR glasses.

The L Shaped battery is designed to meet the non-square internal space of the device, and maximize the space utilization and capacity.

Winding Vs. Stacking battery process technology

The Prismetic battery is generally based on the winding process, but this process also limits the shape it can be made. The most competitive advantage of the lamination process is that it can be customized and made into any shape and size according to the requirements and designs from our customers. More importantly, the L-shaped battery can only be produced by the lamination process technology, not winding.

Winging Process Technology

Can not change the shape, can only be made
into a square;Limited capacity due to unavailable space;
Lower rate, unable to achieve high rate charge and discharge.

Stacking Process Technology

Customized the shaped batteries according to the product design
(limited internal structure);
Clients determined the length, width, height, and shape requirements;
Maximize the utilization of the irregular space inside the fuselage,
and maximize the capacity;Max. 50C rate continuous discharge,
support Max. 5C fast charge;
Integrated production process;
Flexible manufacturing: Accept
small batch production and sampling.
