Solid State Technology Batteries
Unlike traditional lithium-ion batteries, which use liquid electrolytes, the solid-state technology batteries electrolytes do not. This fundamental difference enhances safety, cycle life, and overall performance. They can be overcharged, heated to extreme values, and even punctured with a projectile with no ill effects.
We can develop batteries equipped with a hardware override switch to bypass all electronic control systems if necessary. As overcharge, over-discharge, short circuits, and similar issues have minimal impact other than reducing battery life, you can be assured of accessing the power you need, regardless of the situation.
This technology also extends the usable cycle life to over 10,000 cycles, making it more environmentally friendly and cost-effective. By prolonging the lifespan of materials and increasing the return on investment, it offers significant ecological and economic benefits.

PERFORMANCE AND LIFETIME
Like all batteries, also EPTechnologies batteries age, by usage and by calendar aging. Calendar aging is around 1% per year if kept below 30 deg storage temp and if stored at 50 to 60% SOC.
With repeated charging and discharging (cyclical ageing).
