● There is no battery leakage problem. The battery does not contain liquid electrolyte and uses colloidal solids.

● Since it is liquid-free, it can be combined into multiple layers within a single chip to achieve high voltage.

● Battery can be designed into various shapes.

● The capacity will be twice that of a lithium-ion battery of the same size.

● The battery suffers from external short circuit or overcharge, reverse charge (forced over-discharge).

● The battery is continuously overcharged by high-rate and large current, causing the battery core to expand and the positive electrode to be in direct contact and short-circuited.

● The battery has an internal short circuit, or a micro short circuit, such as: the positive and negative electrodes have burrs that penetrate the separator paper and are short-circuited, the positive and negative electrodes are improperly placed, resulting in a short-circuit, or the positive electrode contacts the steel shell and is short-circuited, and the negative electrode falls out and enters the separator. The paper and separator paper itself are defective, and the positive electrode tab contacts the negative electrode piece and is short-circuited.

● Whether a single battery has zero voltage.

● Plug short circuit, open circuit, poor connection with plug.

● Desoldering and virtual soldering of leads and battery.

● Incorrect internal connection of the battery, missing soldering, virtual soldering, desoldering between the connecting piece and the battery, etc.

● The internal electronic components of the battery are incorrectly connected and damaged.

● The battery has zero voltage or there is a zero-voltage battery in the battery pack.

● Battery pack connection error, internal electronic components, protection circuit abnormalities.

● Charging equipment failure, no output current.

● External factors cause charging efficiency to be too low (such as extremely low or high temperature).

● The battery life will decrease after storage and use.

● Insufficient charging or no charging.

● The ambient temperature is too low.

● The discharge efficiency is low. For example, when a large current is discharged, an ordinary battery cannot discharge electricity because the internal material diffusion speed cannot keep up with the reaction speed, causing the voltage to drop sharply.
