Leoch International Technology : How do lithium-ion and lead-acid batteries compare?2023.11.01

Lithium-ionand lead-acidbatteries are no longer unfamiliar today.

But you want to understand the two kinds of batteries at once is still a little difficulty, while many newcomers still have some doubts, here we compile the relevant content to help you quickly and intuitively understand the two kinds of batteries.

1、The overview and principle

Lead-acid battery is a kind of battery made of lead and its oxides, the electrolyte is sulfuric acid solution.

When charging, electrical energy is converted into chemical energy, and chemical energy is converted into electrical energy when discharging.

It is widely used in electric bicycles, motorcycles and other fields.

Lithium batteries are made of lithium metal or lithium alloy as positive/negative materials, using non-aqueous electrolyte solution.

Lithium batteries can be divided into lithium metal batteries and lithium ion batteries, of which lithium ion batteries are rechargeable.

It works by the transfer of lithium ions between the positive and negative electrodes to achieve the storage and release of electrical energy.

2、6Different Comparison Latitudes

Safety: Lead-acid batteries are relatively safe.

Environmental protection: Lithium batteries are less polluting in some scenarios.

Price: lead-acid batteries with the same capacity have certain advantages.

Energy density: Lithium battery has higher energy density.

Self-discharge rate: lithium batteries have a lower self-discharge rate.

Service life: Usually, lithium batteries are designed to last longer than lead-acid batteries.

3、Summarize

Lead-acid batteries and lithium batteries have their own advantages and characteristics in different latitudes.

Lead-acid batteries perform better in terms of safety, price and environmental protection.

Lithium batteries have advantages in energy density, self-discharge rate and service life.

But it is not absolute, the two applicable fields are also interspersed.

But remember, the two batteries have their own advantages, the choice of which battery should be based on specific needs and application scenarios to decide.

Leoch has two business lines in"Lead-acid + Lithium-Ion", with more than a decade of industry research and development, has accumulated muchproduct experience and practice cases, in the face of various types of power supply application scenarios, Leoch can be in accordance with the actual situation and the needs of customers with reasonable matching of lead-acid or lithium batteries, to help customers to save costs, to achieve the goal.
